>= 12.0.0
------
* The original librados rados_objects_list_open (C) and objects_begin
(C++) object listing API, deprecated in Hammer, has finally been
removed. Users of this interface must update their software to use
either the rados_nobjects_list_open (C) and nobjects_begin (C++) API or
the new rados_object_list_begin (C) and object_list_begin (C++) API
before updating the client-side librados library to Luminous.
Object enumeration (via any API) with the latest librados version
and pre-Hammer OSDs is no longer supported. Note that no in-tree
Ceph services rely on object enumeration via the deprecated APIs, so
only external librados users might be affected.
The newest (and recommended) rados_object_list_begin (C) and
object_list_begin (C++) API is only usable on clusters with the
SORTBITWISE flag enabled (Jewel and later). (Note that this flag is
required to be set before upgrading beyond Jewel.)
* CephFS clients without the 'p' flag in their authentication capability
string will no longer be able to set quotas or any layout fields. This
flag previously only restricted modification of the pool and namespace
fields in layouts.
* CephFS directory fragmentation (large directory support) is enabled
by default on new filesystems. To enable it on existing filesystems
use "ceph fs set <fs_name> allow_dirfrags".
* CephFS will generate a health warning if you have fewer standby daemons
than it thinks you wanted. By default this will be 1 if you ever had
a standby, and 0 if you did not. You can customize this using
``ceph fs set <fs> standby_count_wanted <number>``. Setting it
to zero will effectively disable the health check.
* The "ceph mds tell ..." command has been removed. It is superceded
by "ceph tell mds.<id> ..."
* The "journaler allow split entries" config setting has been removed.
* The 'apply' mode of cephfs-journal-tool has been removed
12.0.0
------
@ -121,3 +92,93 @@
* The 'rados df' JSON output now prints numeric values as numbers instead of
strings.
* There was a bug introduced in Jewel (#19119) that broke the mapping behavior
when an "out" OSD that still existed in the CRUSH map was removed with 'osd rm'.
This could result in 'misdirected op' and other errors. The bug is now fixed,
but the fix itself introduces the same risk because the behavior may vary between
clients and OSDs. To avoid problems, please ensure that all OSDs are removed
from the CRUSH map before deleting them. That is, be sure to do::
ceph osd crush rm osd.123
before::
ceph osd rm osd.123

12.1.0
------
* The ``mon_osd_max_op_age`` option has been renamed to
``mon_osd_warn_op_age`` (default: 32 seconds), to indicate we
generate a warning at this age. There is also a new
``mon_osd_err_op_age_ratio`` that is a expressed as a multitple of
``mon_osd_warn_op_age`` (default: 128, for roughly 60 minutes) to
control when an error is generated.
* The default maximum size for a single RADOS object has been reduced from
100GB to 128MB. The 100GB limit was completely impractical in practice
while the 128MB limit is a bit high but not unreasonable. If you have an
application written directly to librados that is using objects larger than
128MB you may need to adjust ``osd_max_object_size``.
* The semantics of the 'rados ls' and librados object listing
operations have always been a bit confusing in that "whiteout"
objects (which logically don't exist and will return ENOENT if you
try to access them) are included in the results. Previously
whiteouts only occurred in cache tier pools. In luminous, logically
deleted but snapshotted objects now result in a whiteout object, and
as a result they will appear in 'rados ls' results, even though
trying to read such an object will result in ENOENT. The 'rados
listsnaps' operation can be used in such a case to enumerate which
snapshots are present.
This may seem a bit strange, but is less strange than having a
deleted-but-snapshotted object not appear at all and be completely
hidden from librados's ability to enumerate objects. Future
versions of Ceph will likely include an alternative object
enumeration interface that makes it more natural and efficient to
enumerate all objects along with their snapshot and clone metadata.
* The deprecated 'crush_ruleset' property has finally been removed; please use
'crush_rule' instead for the 'osd pool get ...' and 'osd pool set ..' commands.
* The 'osd pool default crush replicated ruleset' option has been
removed and replaced by the 'osd pool default crush rule' option.
By default it is -1, which means the mon will pick the first type
replicated rule in the CRUSH map for replicated pools. Erasure
coded pools have rules that are automatically created for them if they are
not specified at pool creation time.

CephFS has a configurable maximum file size, and it's 1TB by default.

Setting ``max_file_size`` to 0 does not disable the limit. It would

----------------------------------
CephFS enforces the maximum file size limit at the point of appending to
files or setting their size. It does not affect how anything is stored.
When users create a file of an enormous size (without necessarily
writing any data to it), some operations (such as deletes) cause the MDS
to have to do a large number of operations to check if any of the RADOS
objects within the range that could exist (according to the file size)
really existed.
The ``max_file_size`` setting prevents users from creating files that
appear to be eg. exabytes in size, causing load on the MDS as it tries

===============================
Ceph filesystem client eviction
===============================
@ -6,114 +7,139 @@ When a filesystem client is unresponsive or otherwise misbehaving, it
may be necessary to forcibly terminate its access to the filesystem. This
process is called *eviction*.
This process is somewhat thorough in order to protect against data inconsistency
resulting from misbehaving clients.
Evicting a CephFS client prevents it from communicating further with MDS
daemons and OSD daemons. If a client was doing buffered IO to the filesystem,
any un-flushed data will be lost.
OSD blacklisting
----------------
Clients may either be evicted automatically (if they fail to communicate
promptly with the MDS), or manually (by the system administrator).
First, prevent the client from performing any more data operations by *blacklisting*
it at the RADOS level. You may be familiar with this concept as *fencing* in other
storage systems.
The client eviction process applies to clients of all kinds, this includes
FUSE mounts, kernel mounts, nfs-ganesha gateways, and any process using
libcephfs.
Identify the client to evict from the MDS session list:
Automatic client eviction
=========================
There are two situations in which a client may be evicted automatically:
On an active MDS daemon, if a client has not communicated with the MDS for
over ``mds_session_autoclose`` seconds (300 seconds by default), then it
will be evicted automatically.
During MDS startup (including on failover), the MDS passes through a
state called ``reconnect``. During this state, it waits for all the
clients to connect to the new MDS daemon. If any clients fail to do
so within the time window (``mds_reconnect_timeout``, 45 seconds by default)
then they will be evicted.
A warning message is sent to the cluster log if either of these situations
arises.
Manual client eviction
======================
Sometimes, the administrator may want to evict a client manually. This
could happen if a client is died and the administrator does not
want to wait for its session to time out, or it could happen if
a client is misbehaving and the administrator does not have access to
the client node to unmount it.
It is useful to inspect the list of clients first:
::
# ceph daemon mds.a session ls
ceph tell mds.0 client ls
[
{ "id": 4117,
"num_leases": 0,
"num_caps": 1,
"state": "open",
"replay_requests": 0,
"reconnecting": false,
"inst": "client.4117 172.16.79.251:0\/3271",
"client_metadata": { "entity_id": "admin",
"hostname": "fedoravm.localdomain",
"mount_point": "\/home\/user\/mnt"}}]
{
"id": 4305,
"num_leases": 0,
"num_caps": 3,
"state": "open",
"replay_requests": 0,
"completed_requests": 0,
"reconnecting": false,
"inst": "client.4305 172.21.9.34:0/422650892",
"client_metadata": {
"ceph_sha1": "ae81e49d369875ac8b569ff3e3c456a31b8f3af5",
"ceph_version": "ceph version 12.0.0-1934-gae81e49 (ae81e49d369875ac8b569ff3e3c456a31b8f3af5)",
"entity_id": "0",
"hostname": "senta04",
"mount_point": "/tmp/tmpcMpF1b/mnt.0",
"pid": "29377",
"root": "/"
}
}
]
In this case the 'fedoravm' client has address ``172.16.79.251:0/3271``, so we blacklist
it as follows:
Once you have identified the client you want to evict, you can
do that using its unique ID, or various other attributes to identify it:
::
# ceph osd blacklist add 172.16.79.251:0/3271
blacklisting 172.16.79.251:0/3271 until 2014-12-09 13:09:56.569368 (3600 sec)
# These all work
ceph tell mds.0 client evict id=4305
ceph tell mds.0 client evict client_metadata.=4305
OSD epoch barrier
-----------------
While the evicted client is now marked as blacklisted in the central (mon) copy of the OSD
map, it is now necessary to ensure that this OSD map update has propagated to all daemons
involved in subsequent filesystem I/O. To do this, use the ``osdmap barrier`` MDS admin
socket command.
Advanced: Un-blacklisting a client
==================================
First read the latest OSD epoch:
Ordinarily, a blacklisted client may not reconnect to the servers: it
must be unmounted and then mounted anew.
However, in some situations it may be useful to permit a client that
was evicted to attempt to reconnect.
Because CephFS uses the RADOS OSD blacklist to control client eviction,
CephFS clients can be permitted to reconnect by removing them from
the blacklist:
::
# ceph osd dump
epoch 12
fsid fd61ca96-53ff-4311-826c-f36b176d69ea
created 2014-12-09 12:03:38.595844
modified 2014-12-09 12:09:56.619957
...
ceph osd blacklist ls
# ... identify the address of the client ...
ceph osd blacklist rm <address>
In this case it is 12. Now request the MDS to barrier on this epoch:
Doing this may put data integrity at risk if other clients have accessed
files that the blacklisted client was doing buffered IO to. It is also not
guaranteed to result in a fully functional client -- the best way to get
a fully healthy client back after an eviction is to unmount the client
and do a fresh mount.
::
If you are trying to reconnect clients in this way, you may also
find it useful to set ``client_reconnect_stale`` to true in the
FUSE client, to prompt the client to try to reconnect.
# ceph daemon mds.a osdmap barrier 12
Advanced: Configuring blacklisting
==================================
MDS session eviction
--------------------
If you are experiencing frequent client evictions, due to slow
client hosts or an unreliable network, and you cannot fix the underlying
issue, then you may want to ask the MDS to be less strict.
Finally, it is safe to evict the client's MDS session, such that any capabilities it held
may be issued to other clients. The ID here is the ``id`` attribute from the ``session ls``
output:
It is possible to respond to slow clients by simply dropping their
MDS sessions, but permit them to re-open sessions and permit them
to continue talking to OSDs. To enable this mode, set
``mds_session_blacklist_on_timeout`` to false on your MDS nodes.
::
For the equivalent behaviour on manual evictions, set
``mds_session_blacklist_on_evict`` to false.
# ceph daemon mds.a session evict 4117
Note that if blacklisting is disabled, then evicting a client will
only have an effect on the MDS you send the command to. On a system
with multiple active MDS daemons, you would need to send an
eviction command to each active daemon. When blacklisting is enabled
(the default), sending an eviction to command to just a single
MDS is sufficient, because the blacklist propagates it to the others.
That's it! The client has now been evicted, and any resources it had locked will
now be available for other clients.
Advanced options
================
Background: OSD epoch barrier
-----------------------------
``mds_blacklist_interval`` - this setting controls how many seconds
entries will remain in the blacklist for.
The purpose of the barrier is to ensure that when we hand out any
capabilities which might allow touching the same RADOS objects, the
clients we hand out the capabilities to must have a sufficiently recent
OSD map to not race with cancelled operations (from ENOSPC) or
blacklisted clients (from evictions)
More specifically, the cases where we set an epoch barrier are:
* Client eviction (where the client is blacklisted and other clients
must wait for a post-blacklist epoch to touch the same objects)
* OSD map full flag handling in the client (where the client may
cancel some OSD ops from a pre-full epoch, so other clients must
wait until the full epoch or later before touching the same objects).
* MDS startup, because we don't persist the barrier epoch, so must
assume that latest OSD map is always required after a restart.
Note that this is a global value for simplicity: we could maintain this on
a per-inode basis. We don't, because:
* It would be more complicated
* It would use an extra 4 bytes of memory for every inode
* It would not be much more efficient as almost always everyone has the latest
OSD map anyway, in most cases everyone will breeze through this barrier
rather than waiting.
* We only do this barrier in very rare cases, so any benefit from per-inode
granularity would only very rarely be seen.
The epoch barrier is transmitted along with all capability messages, and
instructs the receiver of the message to avoid sending any more RADOS
operations to OSDs until it has seen this OSD epoch. This mainly applies
to clients (doing their data writes directly to files), but also applies
to the MDS because things like file size probing and file deletion are
done directly from the MDS.

The ``rados`` suite generates thousands of tests out of a few hundred

Step 4 - prepare S3 environment
-------------------------------
The s3-tests suite expects to run in a particular environment (S3 users, keys,
configuration file).
Before you try to prepare the environment, make sure you don't have any
existing keyring or ``ceph.conf`` files in ``/etc/ceph``.
For jewel, Abhishek Lekshmanan wrote a script that can be used for this
purpose. Assuming you are testing jewel, run the following commands from the
``src/`` directory of your ceph clone (where you just started the vstart
cluster)::
pushd ~
wget https://gist.githubusercontent.com/theanalyst/2fee6bc2780f67c79cad7802040fcddc/raw/b497ddba053d9a6fb5d91b73924cbafcfc32f137/s3tests-bootstrap.sh
popd
sh ~/s3tests-bootstrap.sh
If the script is successful, it will display a blob of JSON and create a file
called ``s3.conf`` in the current directory.
Step 5 - run s3-tests
Step 3 - run s3-tests
---------------------
To actually run the tests, take note of the full path to the ``s3.conf`` file
created in the previous step and then move to the directory where you cloned
``s3-tests`` in Step 2.
First, verify that the test suite is there and can be run::
S3TEST_CONF=/path/to/s3.conf ./virtualenv/bin/nosetests -a '!fails_on_rgw' -v --collect-only
This should complete quickly - it is like a "dry run" of all the tests in the
suite.
Finally, run the test suite itself::
S3TEST_CONF=/path/to/s3.conf ./virtualenv/bin/nosetests -a '!fails_on_rgw' -v
Note: the following test is expected to error - this is a problem in the test
setup (WIP), not an actual test failure::

Every value will have either bit 1 or 2 set to indicate the type

If bit 4 is set (average), there will be two values to read, a sum and a count. If it is a counter, the average for the previous interval would be sum delta (since the previous read) divided by the count delta. Alternatively, dividing the values outright would provide the lifetime average value. Normally these are used to measure latencies (number of requests and a sum of request latencies), and the average for the previous interval is what is interesting.

=================
Perf histograms
=================
The perf histograms build on perf counters infrastructure. Histograms are built for a number of counters and simplify gathering data on which groups of counter values occur most often over time.
Perf histograms are currently unsigned 64-bit integer counters, so they're mostly useful for time and sizes. Data dumped by perf histogram can then be feed into other analysis tools/scripts.
Access
------
The perf histogram data are accessed via the admin socket. For example::
ceph daemon osd.0 perf histogram schema
ceph daemon osd.0 perf histogram dump
Collections
-----------
The histograms are grouped into named collections, normally representing a subsystem or an instance of a subsystem. For example, the internal ``throttle`` mechanism reports statistics on how it is throttling, and each instance is named something like::
op_r_latency_out_bytes_histogram
op_rw_latency_in_bytes_histogram
op_rw_latency_out_bytes_histogram
...
Schema
------
The ``perf histogram schema`` command dumps a json description of which values are available, and what their type is. Each named value as a ``type`` bitfield, with the 5-th bit always set and following bits defined.
+------+-------------------------------------+
| bit | meaning |
+======+=====================================+
| 1 | floating point value |
+------+-------------------------------------+
| 2 | unsigned 64-bit integer value |
+------+-------------------------------------+
| 4 | average (sum + count pair) |
+------+-------------------------------------+
| 8 | counter (vs gauge) |
+------+-------------------------------------+
In other words, histogram of type "18" is a histogram of unsigned 64-bit integer values (16 + 2).
Here is an example of the schema output::
{
"AsyncMessenger::Worker-0": {},
"AsyncMessenger::Worker-1": {},
"AsyncMessenger::Worker-2": {},
"mutex-WBThrottle::lock": {},
"objecter": {},

This represents the 2d histogram, consisting of 9 history entrires and 32 value groups per each history entry.
"Ranges" element denote value bounds for each of value groups. "Buckets" denote amount of value groups ("buckets"),
"Min" is a minimum accepted valaue, "quant_size" is quantization unit and "scale_type" is either "log2" (logarhitmic
scale) or "linear" (linear scale).
You can use histogram_dump.py tool (see src/tools/histogram_dump.py) for quick visualisation of existing histogram

Manual Deployment on FreeBSD
==============================
This a largely a copy of the regular Manual Deployment with FreeBSD specifics.
The difference lies in two parts: The underlying diskformat, and the way to use
the tools.
All Ceph clusters require at least one monitor, and at least as many OSDs as
copies of an object stored on the cluster. Bootstrapping the initial monitor(s)
is the first step in deploying a Ceph Storage Cluster. Monitor deployment also
sets important criteria for the entire cluster, such as the number of replicas
for pools, the number of placement groups per OSD, the heartbeat intervals,
whether authentication is required, etc. Most of these values are set by
default, so it's useful to know about them when setting up your cluster for
production.
Following the same configuration as `Installation (Quick)`_, we will set up a
cluster with ``node1`` as the monitor node, and ``node2`` and ``node3`` for
OSD nodes.

Disklayout on FreeBSD
=====================
Current implementation works on ZFS pools
* All Ceph data is created in /var/lib/ceph
* Log files go into /var/log/ceph
* PID files go into /var/log/run
* One ZFS pool is allocated per OSD, like::
gpart create -s GPT ada1
gpart add -t freebsd-zfs -l osd1 ada1
zpool create -o mountpoint=/var/lib/ceph/osd/osd.1 osd
* Some cache and log (ZIL) can be attached.
Please note that this is different from the Ceph journals. Cache and log are
totally transparent for Ceph, and help the filesystem to keep the system
consistant and help performance.
Assuming that ada2 is an SSD::
gpart create -s GPT ada2
gpart add -t freebsd-zfs -l osd1-log -s 1G ada2
zpool add osd1 log gpt/osd1-log
gpart add -t freebsd-zfs -l osd1-cache -s 10G ada2
zpool add osd1 log gpt/osd1-cache
* Note: *UFS2 does not allow large xattribs*
Configuration
-------------
As per FreeBSD default parts of extra software go into ``/usr/local/``. Which
means that for ``/etc/ceph.conf`` the default location is
``/usr/local/etc/ceph/ceph.conf``. Smartest thing to do is to create a softlink
from ``/etc/ceph`` to ``/usr/local/etc/ceph``::
ln -s /usr/local/etc/ceph /etc/ceph
A sample file is provided in ``/usr/local/share/doc/ceph/sample.ceph.conf``
Note that ``/usr/local/etc/ceph/ceph.conf`` will be found by most tools,
linking it to ``/etc/ceph/ceph.conf`` will help with any scripts that are found
in extra tools, scripts, and/or discussionlists.
Monitor Bootstrapping
=====================
Bootstrapping a monitor (a Ceph Storage Cluster, in theory) requires
a number of things:
- **Unique Identifier:** The ``fsid`` is a unique identifier for the cluster,
and stands for File System ID from the days when the Ceph Storage Cluster was
principally for the Ceph Filesystem. Ceph now supports native interfaces,
block devices, and object storage gateway interfaces too, so ``fsid`` is a
bit of a misnomer.
- **Cluster Name:** Ceph clusters have a cluster name, which is a simple string
without spaces. The default cluster name is ``ceph``, but you may specify
a different cluster name. Overriding the default cluster name is
especially useful when you are working with multiple clusters and you need to
clearly understand which cluster your are working with.
For example, when you run multiple clusters in a `federated architecture`_,
the cluster name (e.g., ``us-west``, ``us-east``) identifies the cluster for
the current CLI session. **Note:** To identify the cluster name on the
command line interface, specify the a Ceph configuration file with the
cluster name (e.g., ``ceph.conf``, ``us-west.conf``, ``us-east.conf``, etc.).
Also see CLI usage (``ceph --cluster {cluster-name}``).
- **Monitor Name:** Each monitor instance within a cluster has a unique name.
In common practice, the Ceph Monitor name is the host name (we recommend one
Ceph Monitor per host, and no commingling of Ceph OSD Daemons with
Ceph Monitors). You may retrieve the short hostname with ``hostname -s``.
- **Monitor Map:** Bootstrapping the initial monitor(s) requires you to
generate a monitor map. The monitor map requires the ``fsid``, the cluster
name (or uses the default), and at least one host name and its IP address.
- **Monitor Keyring**: Monitors communicate with each other via a
secret key. You must generate a keyring with a monitor secret and provide
it when bootstrapping the initial monitor(s).
- **Administrator Keyring**: To use the ``ceph`` CLI tools, you must have
a ``client.admin`` user. So you must generate the admin user and keyring,
and you must also add the ``client.admin`` user to the monitor keyring.
The foregoing requirements do not imply the creation of a Ceph Configuration
file. However, as a best practice, we recommend creating a Ceph configuration
file and populating it with the ``fsid``, the ``mon initial members`` and the
``mon host`` settings.
You can get and set all of the monitor settings at runtime as well. However,
a Ceph Configuration file may contain only those settings that override the
default values. When you add settings to a Ceph configuration file, these
settings override the default settings. Maintaining those settings in a
Ceph configuration file makes it easier to maintain your cluster.
The procedure is as follows:
#. Log in to the initial monitor node(s)::
ssh {hostname}
For example::
ssh node1
#. Ensure you have a directory for the Ceph configuration file. By default,
Ceph uses ``/etc/ceph``. When you install ``ceph``, the installer will
create the ``/etc/ceph`` directory automatically. ::
ls /etc/ceph
**Note:** Deployment tools may remove this directory when purging a
cluster (e.g., ``ceph-deploy purgedata {node-name}``, ``ceph-deploy purge
{node-name}``).
#. Create a Ceph configuration file. By default, Ceph uses
``ceph.conf``, where ``ceph`` reflects the cluster name. ::
sudo vim /etc/ceph/ceph.conf
#. Generate a unique ID (i.e., ``fsid``) for your cluster. ::
uuidgen
#. Add the unique ID to your Ceph configuration file. ::
fsid = {UUID}
For example::
fsid = a7f64266-0894-4f1e-a635-d0aeaca0e993
#. Add the initial monitor(s) to your Ceph configuration file. ::
mon initial members = {hostname}[,{hostname}]
For example::
mon initial members = node1
#. Add the IP address(es) of the initial monitor(s) to your Ceph configuration
file and save the file. ::
mon host = {ip-address}[,{ip-address}]
For example::
mon host = 192.168.0.1
**Note:** You may use IPv6 addresses instead of IPv4 addresses, but
you must set ``ms bind ipv6`` to ``true``. See `Network Configuration
Reference`_ for details about network configuration.
#. Create a keyring for your cluster and generate a monitor secret key. ::
ceph-authtool --create-keyring /tmp/ceph.mon.keyring --gen-key -n mon. --cap mon 'allow *'
#. Generate an administrator keyring, generate a ``client.admin`` user and add
the user to the keyring. ::
sudo ceph-authtool --create-keyring /etc/ceph/ceph.client.admin.keyring --gen-key -n client.admin --set-uid=0 --cap mon 'allow *' --cap osd 'allow *' --cap mds 'allow'
#. Add the ``client.admin`` key to the ``ceph.mon.keyring``. ::
ceph-authtool /tmp/ceph.mon.keyring --import-keyring /etc/ceph/ceph.client.admin.keyring
#. Generate a monitor map using the hostname(s), host IP address(es) and the FSID.
Save it as ``/tmp/monmap``::
monmaptool --create --add {hostname} {ip-address} --fsid {uuid} /tmp/monmap
For example::
monmaptool --create --add node1 192.168.0.1 --fsid a7f64266-0894-4f1e-a635-d0aeaca0e993 /tmp/monmap
#. Create a default data directory (or directories) on the monitor host(s). ::
sudo mkdir /var/lib/ceph/mon/{cluster-name}-{hostname}
For example::
sudo mkdir /var/lib/ceph/mon/ceph-node1
See `Monitor Config Reference - Data`_ for details.
#. Populate the monitor daemon(s) with the monitor map and keyring. ::
sudo -u ceph ceph-mon [--cluster {cluster-name}] --mkfs -i {hostname} --monmap /tmp/monmap --keyring /tmp/ceph.mon.keyring
For example::
sudo -u ceph ceph-mon --mkfs -i node1 --monmap /tmp/monmap --keyring /tmp/ceph.mon.keyring
#. Consider settings for a Ceph configuration file. Common settings include
the following::
[global]
fsid = {cluster-id}
mon initial members = {hostname}[, {hostname}]
mon host = {ip-address}[, {ip-address}]
public network = {network}[, {network}]
cluster network = {network}[, {network}]
auth cluster required = cephx
auth service required = cephx
auth client required = cephx
osd journal size = {n}
osd pool default size = {n} # Write an object n times.
osd pool default min size = {n} # Allow writing n copy in a degraded state.
osd pool default pg num = {n}
osd pool default pgp num = {n}
osd crush chooseleaf type = {n}
In the foregoing example, the ``[global]`` section of the configuration might
look like this::
[global]
fsid = a7f64266-0894-4f1e-a635-d0aeaca0e993
mon initial members = node1
mon host = 192.168.0.1
public network = 192.168.0.0/24
auth cluster required = cephx
auth service required = cephx
auth client required = cephx
osd journal size = 1024
osd pool default size = 2
osd pool default min size = 1
osd pool default pg num = 333
osd pool default pgp num = 333
osd crush chooseleaf type = 1
#. Touch the ``done`` file.
Mark that the monitor is created and ready to be started::
sudo touch /var/lib/ceph/mon/ceph-node1/done
#. And for FreeBSD an entry for every monitor needs to be added to the config
file. (The requirement will be removed in future releases).
The entry should look like::
[mon]
[mon.node1]
host = node1 # this name can be resolve
#. Start the monitor(s).
For Ubuntu, use Upstart::
sudo start ceph-mon id=node1 [cluster={cluster-name}]
In this case, to allow the start of the daemon at each reboot you
must create two empty files like this::
sudo touch /var/lib/ceph/mon/{cluster-name}-{hostname}/upstart
For example::
sudo touch /var/lib/ceph/mon/ceph-node1/upstart
For Debian/CentOS/RHEL, use sysvinit::
sudo /etc/init.d/ceph start mon.node1
For FreeBSD we use the rc.d init scripts (called bsdrc in Ceph)::
sudo service ceph start start mon.node1
For this to work /etc/rc.conf also needs the entry to enable ceph::
cat 'ceph_enable="YES"' >> /etc/rc.conf
#. Verify that Ceph created the default pools. ::
ceph osd lspools
You should see output like this::
0 data,1 metadata,2 rbd,
#. Verify that the monitor is running. ::
ceph -s
You should see output that the monitor you started is up and running, and
you should see a health error indicating that placement groups are stuck
inactive. It should look something like this::
cluster a7f64266-0894-4f1e-a635-d0aeaca0e993
health HEALTH_ERR 192 pgs stuck inactive; 192 pgs stuck unclean; no osds
monmap e1: 1 mons at {node1=192.168.0.1:6789/0}, election epoch 1, quorum 0 node1
osdmap e1: 0 osds: 0 up, 0 in
pgmap v2: 192 pgs, 3 pools, 0 bytes data, 0 objects
0 kB used, 0 kB / 0 kB avail
192 creating
**Note:** Once you add OSDs and start them, the placement group health errors
should disappear. See the next section for details.
Adding OSDs
===========
Once you have your initial monitor(s) running, you should add OSDs. Your cluster
cannot reach an ``active + clean`` state until you have enough OSDs to handle the
number of copies of an object (e.g., ``osd pool default size = 2`` requires at
least two OSDs). After bootstrapping your monitor, your cluster has a default
CRUSH map; however, the CRUSH map doesn't have any Ceph OSD Daemons mapped to
a Ceph Node.
Short Form
----------
Ceph provides the ``ceph-disk`` utility, which can prepare a disk, partition or
directory for use with Ceph. The ``ceph-disk`` utility creates the OSD ID by
incrementing the index. Additionally, ``ceph-disk`` will add the new OSD to the
CRUSH map under the host for you. Execute ``ceph-disk -h`` for CLI details.
The ``ceph-disk`` utility automates the steps of the `Long Form`_ below. To
create the first two OSDs with the short form procedure, execute the following
on ``node2`` and ``node3``:
#. Prepare the OSD. ::
On FreeBSD only existing directories can be use to create OSDs in::
ssh {node-name}
sudo ceph-disk prepare --cluster {cluster-name} --cluster-uuid {uuid} {path-to-ceph-osd-directory}
For example::
ssh node1
sudo ceph-disk prepare --cluster ceph --cluster-uuid a7f64266-0894-4f1e-a635-d0aeaca0e993 /var/lib/ceph/osd/osd.1
#. Activate the OSD::
sudo ceph-disk activate {data-path} [--activate-key {path}]
For example::
sudo ceph-disk activate /var/lib/ceph/osd/osd.1
**Note:** Use the ``--activate-key`` argument if you do not have a copy
of ``/var/lib/ceph/bootstrap-osd/{cluster}.keyring`` on the Ceph Node.
FreeBSD does not auto start the OSDs, but also requires a entry in
``ceph.conf``. One for each OSD::
[osd]
[osd.1]
host = node1 # this name can be resolve
Long Form
---------
Without the benefit of any helper utilities, create an OSD and add it to the
cluster and CRUSH map with the following procedure. To create the first two
OSDs with the long form procedure, execute the following on ``node2`` and
``node3``:
#. Connect to the OSD host. ::
ssh {node-name}
#. Generate a UUID for the OSD. ::
uuidgen
#. Create the OSD. If no UUID is given, it will be set automatically when the
OSD starts up. The following command will output the OSD number, which you
will need for subsequent steps. ::
ceph osd create [{uuid} [{id}]]
#. Create the default directory on your new OSD. ::
ssh {new-osd-host}
sudo mkdir /var/lib/ceph/osd/{cluster-name}-{osd-number}
Above are the ZFS instructions to do this for FreeBSD.
#. If the OSD is for a drive other than the OS drive, prepare it
for use with Ceph, and mount it to the directory you just created.
#. Initialize the OSD data directory. ::
ssh {new-osd-host}
sudo ceph-osd -i {osd-num} --mkfs --mkkey --osd-uuid [{uuid}]
The directory must be empty before you can run ``ceph-osd`` with the
``--mkkey`` option. In addition, the ceph-osd tool requires specification
of custom cluster names with the ``--cluster`` option.
#. Register the OSD authentication key. The value of ``ceph`` for
``ceph-{osd-num}`` in the path is the ``$cluster-$id``. If your
cluster name differs from ``ceph``, use your cluster name instead.::
sudo ceph auth add osd.{osd-num} osd 'allow *' mon 'allow profile osd' -i /var/lib/ceph/osd/{cluster-name}-{osd-num}/keyring
#. Add your Ceph Node to the CRUSH map. ::
ceph [--cluster {cluster-name}] osd crush add-bucket {hostname} host
For example::
ceph osd crush add-bucket node1 host
#. Place the Ceph Node under the root ``default``. ::
ceph osd crush move node1 root=default
#. Add the OSD to the CRUSH map so that it can begin receiving data. You may
also decompile the CRUSH map, add the OSD to the device list, add the host as a
bucket (if it's not already in the CRUSH map), add the device as an item in the
host, assign it a weight, recompile it and set it. ::
ceph [--cluster {cluster-name}] osd crush add {id-or-name} {weight} [{bucket-type}={bucket-name} ...]
For example::
ceph osd crush add osd.0 1.0 host=node1
#. After you add an OSD to Ceph, the OSD is in your configuration. However,
it is not yet running. The OSD is ``down`` and ``in``. You must start
your new OSD before it can begin receiving data.
For Ubuntu, use Upstart::
sudo start ceph-osd id={osd-num} [cluster={cluster-name}]
For example::
sudo start ceph-osd id=0
sudo start ceph-osd id=1
For Debian/CentOS/RHEL, use sysvinit::
sudo /etc/init.d/ceph start osd.{osd-num} [--cluster {cluster-name}]
For example::
sudo /etc/init.d/ceph start osd.0
sudo /etc/init.d/ceph start osd.1
In this case, to allow the start of the daemon at each reboot you
must create an empty file like this::
sudo touch /var/lib/ceph/osd/{cluster-name}-{osd-num}/sysvinit
For example::
sudo touch /var/lib/ceph/osd/ceph-0/sysvinit
sudo touch /var/lib/ceph/osd/ceph-1/sysvinit
Once you start your OSD, it is ``up`` and ``in``.
For FreeBSD using rc.d init::
After adding the OSD to ``ceph.conf``
sudo service ceph start osd.{osd-num}
For example::
sudo service ceph start osd.0
sudo service ceph start osd.1
In this case, to allow the start of the daemon at each reboot you
must create an empty file like this::
sudo touch /var/lib/ceph/osd/{cluster-name}-{osd-num}/bsdrc
For example::
sudo touch /var/lib/ceph/osd/ceph-0/bsdrc
sudo touch /var/lib/ceph/osd/ceph-1/bsdrc
Once you start your OSD, it is ``up`` and ``in``.
Adding MDS
==========
In the below instructions, ``{id}`` is an arbitrary name, such as the hostname of the machine.
#. Create the mds data directory.::
mkdir -p /var/lib/ceph/mds/{cluster-name}-{id}
#. Create a keyring.::
ceph-authtool --create-keyring /var/lib/ceph/mds/{cluster-name}-{id}/keyring --gen-key -n mds.{id}
#. Import the keyring and set caps.::
ceph auth add mds.{id} osd "allow rwx" mds "allow" mon "allow profile mds" -i /var/lib/ceph/mds/{cluster}-{id}/keyring
#. Add to ceph.conf.::
[mds.{id}]
host = {id}
#. Start the daemon the manual way.::
ceph-mds --cluster {cluster-name} -i {id} -m {mon-hostname}:{mon-port} [-f]
#. Start the daemon the right way (using ceph.conf entry).::
service ceph start
#. If starting the daemon fails with this error::
mds.-1.0 ERROR: failed to authenticate: (22) Invalid argument
Then make sure you do not have a keyring set in ceph.conf in the global section; move it to the client section; or add a keyring setting specific to this mds daemon. And verify that you see the same key in the mds data directory and ``ceph auth get mds.{id}`` output.
#. Now you are ready to `create a Ceph filesystem`_.
Summary
=======
Once you have your monitor and two OSDs up and running, you can watch the
placement groups peer by executing the following::
ceph -w
To view the tree, execute the following::
ceph osd tree
You should see output that looks something like this::
# id weight type name up/down reweight
-1 2 root default
-2 2 host node1
0 1 osd.0 up 1
-3 1 host node2
1 1 osd.1 up 1

Manual setup

Create an authentication key for your daemon::
Usually, you would set up a ceph-mgr daemon using a tool such
as ceph-ansible. These instructions describe how to set up
a ceph-mgr daemon manually.
ceph auth get-or-create mgr.$name mon 'allow *'
First, create an authentication key for your daemon::
ceph auth get-or-create mgr.$name mon 'allow profile mgr' osd 'allow *' mds 'allow *'
Place that key into ``mgr data`` path, which for a cluster "ceph"
and mgr $name "foo" would be ``/var/lib/ceph/mgr/ceph-foo``.

Client authentication
---------------------
The manager is a new daemon which requires new CephX capabilities. If you upgrade
a cluster from an old version of Ceph, or use the default install/deploy tools,
your admin client should get this capability automatically. If you use tooling from
elsewhere, you may get EACCES errors when invoking certain ceph cluster commands.
To fix that, add a "mgr allow *" stanza to your client's cephx capabilities by
`Modifying User Capabilities`_.

dashboard plugin
================
Dashboard plugin visualizes the statistics of the cluster using a web server
hosted by ``ceph-mgr``. Like most web applications, dashboard binds to a host
name and port. Since each ``ceph-mgr`` hosts its own instance of dashboard, we
need to configure them separately. The hostname and port are stored using the
configuration key facility. So we can configure them like::
ceph config-key put mgr/dashboard/$name/server_addr $IP
ceph config-key put mgr/dashboard/$name/server_port $PORT
where ``$name`` is the ID of the ceph-mgr who is hosting this dashboard web app.
If they are not configured, the web app will be bound to ``127.0.0.1:7000``.

to provide additional monitoring and interfaces to external monitoring
and management systems.
Since the 12.x (*luminous*) Ceph release, the ceph-mgr daemon is required for
normal operations. The ceph-mgr daemon is an optional component in
the 11.x (*kraken*) Ceph release.
By default, the manager daemon requires no additional configuration, beyond
ensuring it is running. If there is no mgr daemon running, you will
see a health warning to that effect, and some of the other information
in the output of `ceph status` will be missing or stale until a mgr is started.
Use your normal deployment tools, such as ceph-ansible or ceph-deploy, to
set up ceph-mgr daemons on each of your mon nodes. It is not mandatory
to place mgr daemons on the same nodes as mons, but it is almost always
sensible.

restful plugin
==============
RESTful plugin offers the REST API access to the status of the cluster. RESTful
plugin enables you to secure the API endpoints via SSL. If you don't have a
security certificate and key already, you need to create them first::
openssl req -new -nodes -x509 \
-subj "/O=IT/CN=ceph-mgr-restful" \
-days 3650 -keyout $PKEY -out $CERT -extensions v3_ca
where ``$PKEY`` and ``$CERT`` are the paths to the private key and the
certificate. And then you need to import the keystore to the cluster using the
configuration key facility, so RESTful plugin can read them at startup::
ceph config-key put mgr/restful/$name/crt -i $CERT
ceph config-key put mgr/restful/$name/key -i $PKEY
Also, like other web applications, RESTful plugin is bound to the a hostname and
a port::
ceph config-key put mgr/restful/$name/server_addr $IP
ceph config-key put mgr/restful/$name/server_port $PORT
If not specified, the plugin uses ``127.0.0.1:8003`` by default.

OSDs Report Down OSDs
=====================
By default, a Ceph OSD Daemon must report to the Ceph Monitors that another Ceph
OSD Daemon is ``down`` three times before the Ceph Monitors acknowledge that the
reported Ceph OSD Daemon is ``down``. By default, only one
Ceph OSD Daemon is required to report another Ceph OSD Daemon ``down``. You can
change the number of Ceph OSD Daemones required to report a Ceph OSD Daemon
``down`` to a Ceph Monitor by adding an ``mon osd min down reporters`` setting
(``osd min down reporters`` prior to v0.62) under the ``[mon]`` section of your
Ceph configuration file, or by setting the value at runtime.
By default, two Ceph OSD Daemons from different hosts must report to the Ceph
Monitors that another Ceph OSD Daemon is ``down`` before the Ceph Monitors
acknowledge that the reported Ceph OSD Daemon is ``down``. But there is chance
that all the OSDs reporting the failure are hosted in a rack with a bad switch
which has trouble connecting to another OSD. To avoid this sort of false alarm,
we consider the peers reporting a failure a proxy for a potential "subcluster"
over the overall cluster that is similarly laggy. This is clearly not true in
all cases, but will sometimes help us localize the grace correction to a subset
of the system that is unhappy. ``mon osd reporter subtree level`` is used to
group the peers into the "subcluster" by their common ancestor type in CRUSH
map. By default, only two reports from different subtree are required to report
another Ceph OSD Daemon ``down``. You can change the number of reporters from
unique subtrees and the common ancestor type required to report a Ceph OSD
Daemon ``down`` to a Ceph Monitor by adding an ``mon osd min down reporters``
and ``mon osd reporter subtree level`` settings under the ``[mon]`` section of
your Ceph configuration file, or by setting the value at runtime.

If you run "ceph daemon osd.<id> dump_historic_ops" or "dump_ops_in_flight",
you will see a set of operations and a list of events each operation went
through. These are briefly described below.
Events from the Messenger layer:
- header_read: when the messenger first started reading the message off the wire
- throttled: when the messenger tried to acquire memory throttle space to read
the message into memory
- all_read: when the messenger finished reading the message off the wire
- dispatched: when the messenger gave the message to the OSD
- Initiated: <This is identical to header_read. The existence of both is a
historical oddity.
Events from the OSD as it prepares operations
- queued_for_pg: the op has been put into the queue for processing by its PG
- reached_pg: the PG has started doing the op
- waiting for *: the op is waiting for some other work to complete before it
can proceed (a new OSDMap; for its object target to scrub; for the PG to
finish peering; all as specified in the message)
- started: the op has been accepted as something the OSD should actually do
(reasons not to do it: failed security/permission checks; out-of-date local
state; etc) and is now actually being performed
- waiting for subops from: the op has been sent to replica OSDs
Events from the FileStore
- commit_queued_for_journal_write: the op has been given to the FileStore
- write_thread_in_journal_buffer: the op is in the journal's buffer and waiting
to be persisted (as the next disk write)
- journaled_completion_queued: the op was journaled to disk and its callback
queued for invocation
Events from the OSD after stuff has been given to local disk
- op_commit: the op has been committed (ie, written to journal) by the
primary OSD
- op_applied: The op has been write()'en to the backing FS (ie, applied in
memory but not flushed out to disk) on the primary
- sub_op_applied: op_applied, but for a replica's "subop"
- sub_op_committed: op_commited, but for a replica's subop (only for EC pools)
- sub_op_commit_rec/sub_op_apply_rec from <X>: the primary marks this when it
hears about the above, but for a particular replica <X>
- commit_sent: we sent a reply back to the client (or primary OSD, for sub ops)

the internal code (such as passing data across locks into new threads).

Quota statistics are cached on each RGW instance. If there are multiple

each instance will have a different view of quotas. The options that control
this are ``rgw bucket quota ttl``, ``rgw user quota bucket sync interval`` and

enforcement. See `Ceph Object Gateway Config Reference`_

The Ceph Object Gateway supports a subset of the Amazon S3 policy

We do not yet support setting policies on users, groups, or roles.
We use the RGW ‘tenant’ identifier in place of the Amazon twelve-digit
account ID. In the future we may allow you to assign an account ID to
a tenant, but for now if you want to use policies between AWS S3 and
RGW S3 you will have to use the Amazon account ID as the tenant ID when
creating users.
Under AWS, all tenants share a single namespace. RGW gives every
tenant its own namespace of buckets. There may be an option to enable
an AWS-like 'flat' bucket namespace in future versions. At present, to
access a bucket belonging to another tenant, address it as
"tenant:bucket" in the S3 request.
In AWS, a bucket policy can grant access to another account, and that
account owner can then grant access to individual users with user
permissions. Since we do not yet support user, role, and group
permissions, account owners will currently need to grant access
directly to individual users, and granting an entire account access to
a bucket grants access to all users in that account.
Bucket policies do not yet support string interpolation.
Currently, the only condition keys we support are:
- aws:CurrentTime
- aws:EpochTime
- aws:PrincipalType
- aws:Referer
- aws:SecureTransport
- aws:SourceIp
- aws:UserAgent
- aws:username
More may be supported soon as we integrate with the recently rewritten
Authentication/Authorization subsystem.
Swift
=====
There is no way to set bucket policies under Swift, but bucket
policies that have been set govern Swift as well as S3 operations.
Swift credentials are matched against Principals specified in a policy
in a way specific to whatever backend is being used.

=====================================================
Configuring Ceph Object Gateway with Apache/FastCGI
=====================================================
Configuring a Ceph Object Gateway requires a running Ceph Storage Cluster.
Since it contains an embedded webserver (civetweb), the Ceph Object Gateway
does not require an external web server, but it can be configured to use
Apache with the FastCGI module.
.. note:: CGI can pose a security risk.
The Ceph Object Gateway is a client of the Ceph Storage Cluster. As a
Ceph Storage Cluster client, it requires:
- A name for the gateway instance. We use ``gateway`` in this guide.
- A storage cluster user name with appropriate permissions in a keyring.
- Pools to store its data.
- A data directory for the gateway instance.
- An instance entry in the Ceph Configuration file.
- A configuration file for the web server to interact with FastCGI.
Create a User and Keyring
=========================
Each instance must have a user name and key to communicate with a Ceph Storage
Cluster. In the following steps, we use an admin node to create a keyring.
Then, we create a client user name and key. Next, we add the
key to the Ceph Storage Cluster. Finally, we distribute the key ring to
the node containing the gateway instance.
.. topic:: Monitor Key CAPS
When you provide CAPS to the key, you MUST provide read capability.
However, you have the option of providing write capability for the monitor.
This is an important choice. If you provide write capability to the key,
the Ceph Object Gateway will have the ability to create pools automatically;
however, it will create pools with either the default number of placement
groups (not ideal) or the number of placement groups you specified in your
Ceph configuration file. If you allow the Ceph Object Gateway to create
pools automatically, ensure that you have reasonable defaults for the number
of placement groups first. See `Pool Configuration`_ for details.
See `User Management`_ for additional details on Ceph authentication.
#. Generate a Ceph Object Gateway user name and key for each instance. For
exemplary purposes, we will use the name ``gateway`` after ``client.radosgw``::
sudo ceph auth get-or-create client.radosgw.gateway osd 'allow rwx' mon 'allow rwx' -o /etc/ceph/ceph.client.radosgw.keyring
#. Distribute the keyring to the node with the gateway instance. ::
sudo scp /etc/ceph/ceph.client.radosgw.keyring ceph@{hostname}:/home/ceph
ssh {hostname}
sudo mv ceph.client.radosgw.keyring /etc/ceph/ceph.client.radosgw.keyring
.. note:: The 2nd step is optional if ``admin node`` is the ``gateway host``.
Create Pools
============
Ceph Object Gateways require Ceph Storage Cluster pools to store specific
gateway data. If the user you created has permissions, the gateway
will create the pools automatically. However, you should ensure that you have
set an appropriate default number of placement groups per pool into your Ceph
configuration file.
.. note:: Ceph Object Gateways have multiple pools, so don't make the number of
PGs too high considering all of the pools assigned to the same CRUSH
hierarchy, or performance may suffer.
When configuring a gateway with the default region and zone, the naming
convention for pools typically omits region and zone naming, but you can use any
naming convention you prefer. For example:
- ``.rgw.root``
- ``.rgw.control``
- ``.rgw.gc``
- ``.rgw.buckets``
- ``.rgw.buckets.index``
- ``.rgw.buckets.extra``
- ``.log``
- ``.intent-log``
- ``.usage``
- ``.users``
- ``.users.email``
- ``.users.swift``
- ``.users.uid``
See `Configuration Reference - Pools`_ for details on the default pools for
gateways. See `Pools`_ for details on creating pools. As already said, if
write permission is given, Ceph Object Gateway will create pools automatically.
To create a pool manually, execute the following::
ceph osd pool create {poolname} {pg-num} {pgp-num} {replicated | erasure} [{erasure-code-profile}] {ruleset-name} {ruleset-number}
.. tip:: Ceph supports multiple CRUSH hierarchies and CRUSH rulesets, enabling
great flexibility in the way you configure your gateway. Pools such as
``rgw.buckets.index`` may benefit from a pool of SSDs for fast performance.
Backing storage may benefit from the increased economy of erasure-coded
storage, and/or the improved performance from cache tiering.
When you have completed this step, execute the following to ensure that
you have created all of the foregoing pools::
rados lspools
Add a Gateway Configuration to Ceph
===================================
Add the Ceph Object Gateway configuration to your Ceph Configuration file in
``admin node``. The Ceph Object Gateway configuration requires you to
identify the Ceph Object Gateway instance. Then, you must specify the host name
where you installed the Ceph Object Gateway daemon, a keyring (for use with
cephx), the socket path for FastCGI and a log file.
For distros with Apache 2.2 and early versions of Apache 2.4 (RHEL 6, Ubuntu
12.04, 14.04 etc), append the following configuration to ``/etc/ceph/ceph.conf``
in your ``admin node``::
[client.radosgw.gateway]
host = {hostname}
keyring = /etc/ceph/ceph.client.radosgw.keyring
rgw socket path = ""
log file = /var/log/radosgw/client.radosgw.gateway.log
rgw frontends = fastcgi socket_port=9000 socket_host=0.0.0.0
rgw print continue = false
.. note:: Apache 2.2 and early versions of Apache 2.4 do not use Unix Domain
Sockets but use localhost TCP.
For distros with Apache 2.4.9 or later (RHEL 7, CentOS 7 etc), append the
following configuration to ``/etc/ceph/ceph.conf`` in your ``admin node``::
[client.radosgw.gateway]
host = {hostname}
keyring = /etc/ceph/ceph.client.radosgw.keyring
rgw socket path = /var/run/ceph/ceph.radosgw.gateway.fastcgi.sock
log file = /var/log/radosgw/client.radosgw.gateway.log
rgw print continue = false
.. note:: ``Apache 2.4.9`` supports Unix Domain Socket (UDS) but as
``Ubuntu 14.04`` ships with ``Apache 2.4.7`` it doesn't have UDS support and
has to be configured for use with localhost TCP. A bug has been filed for
backporting UDS support in ``Apache 2.4.7`` for ``Ubuntu 14.04``.
See: `Backport support for UDS in Ubuntu Trusty`_
Here, ``{hostname}`` is the short hostname (output of command ``hostname -s``)
of the node that is going to provide the gateway service i.e., the
``gateway host``.
The ``[client.radosgw.gateway]`` portion of the gateway instance identifies this
portion of the Ceph configuration file as configuring a Ceph Storage Cluster
client where the client type is a Ceph Object Gateway (i.e., ``radosgw``).
.. note:: The last line in the configuration i.e., ``rgw print continue = false``
is added to avoid issues with ``PUT`` operations.
Once you finish the setup procedure, if you encounter issues with your
configuration, you can add debugging to the ``[global]`` section of your Ceph
configuration file and restart the gateway to help troubleshoot any
configuration issues. For example::
[global]
#append the following in the global section.
debug ms = 1
debug rgw = 20
Distribute updated Ceph configuration file
==========================================
The updated Ceph configuration file needs to be distributed to all Ceph cluster
nodes from the ``admin node``.
It involves the following steps:
#. Pull the updated ``ceph.conf`` from ``/etc/ceph/`` to the root directory of
the cluster in admin node (e.g. ``my-cluster`` directory). The contents of
``ceph.conf`` in ``my-cluster`` will get overwritten. To do so, execute the
following::
ceph-deploy --overwrite-conf config pull {hostname}
Here, ``{hostname}`` is the short hostname of the Ceph admin node.
#. Push the updated ``ceph.conf`` file from the admin node to all other nodes in
the cluster including the ``gateway host``::
ceph-deploy --overwrite-conf config push [HOST] [HOST...]
Give the hostnames of the other Ceph nodes in place of ``[HOST] [HOST...]``.
Copy ceph.client.admin.keyring from admin node to gateway host
==============================================================
As the ``gateway host`` can be a different node that is not part of the cluster,
the ``ceph.client.admin.keyring`` needs to be copied from the ``admin node`` to
the ``gateway host``. To do so, execute the following on ``admin node``::
sudo scp /etc/ceph/ceph.client.admin.keyring ceph@{hostname}:/home/ceph
ssh {hostname}
sudo mv ceph.client.admin.keyring /etc/ceph/ceph.client.admin.keyring
.. note:: The above step need not be executed if ``admin node`` is the
``gateway host``.
Create Data Directory
=====================
Deployment scripts may not create the default Ceph Object Gateway data
directory. Create data directories for each instance of a ``radosgw``
daemon (if you haven't done so already). The ``host`` variables in the
Ceph configuration file determine which host runs each instance of a
``radosgw`` daemon. The typical form specifies the ``radosgw`` daemon,
the cluster name and the daemon ID.
To create the directory on the ``gateway host``, execute the following::
sudo mkdir -p /var/lib/ceph/radosgw/ceph-radosgw.gateway
Adjust Socket Directory Permissions
===================================
On some distros, the ``radosgw`` daemon runs as the unprivileged ``apache``
UID, and this UID must have write access to the location where it will write
its socket file.
To grant permissions to the default socket location, execute the following on
the ``gateway host``::
sudo chown apache:apache /var/run/ceph
Change Log File Owner
=====================
On some distros, the ``radosgw`` daemon runs as the unprivileged ``apache`` UID,
but the ``root`` user owns the log file by default. You must change it to the
``apache`` user so that Apache can populate the log file. To do so, execute
the following::
sudo chown apache:apache /var/log/radosgw/client.radosgw.gateway.log
Start radosgw service
=====================
The Ceph Object gateway daemon needs to be started. To do so, execute the
following on the ``gateway host``:
On Debian-based distros::
sudo /etc/init.d/radosgw start
On RPM-based distros::
sudo /etc/init.d/ceph-radosgw start
Create a Gateway Configuration file
===================================
On the host where you installed the Ceph Object Gateway i.e., ``gateway host``,
create an ``rgw.conf`` file. Place the file in ``/etc/apache2/conf-available``
directory for ``Debian-based`` distros and in ``/etc/httpd/conf.d`` directory
for ``RPM-based`` distros. It is a Apache configuration file which is needed
for the ``radosgw`` service. This file must be readable by the web server.
Execute the following steps:
#. Create the file:
For Debian-based distros, execute::
sudo vi /etc/apache2/conf-available/rgw.conf
For RPM-based distros, execute::
sudo vi /etc/httpd/conf.d/rgw.conf
#. For distros with Apache 2.2 and early versions of Apache 2.4 that use
localhost TCP and do not support Unix Domain Socket, add the following
contents to the file::
<VirtualHost *:80>
ServerName localhost
DocumentRoot /var/www/html
ErrorLog /var/log/httpd/rgw_error.log
CustomLog /var/log/httpd/rgw_access.log combined

.. note:: For Debian-based distros replace ``/var/log/httpd/``
with ``/var/log/apache2``.
#. For distros with Apache 2.4.9 or later that support Unix Domain Socket,
add the following contents to the file::

Restart Apache
==============
The Apache service needs to be restarted to accept the new configuration.
For Debian-based distros, run::
sudo service apache2 restart
For RPM-based distros, run::
sudo service httpd restart
Or::
sudo systemctl restart httpd
Using The Gateway
=================
To use the REST interfaces, first create an initial Ceph Object Gateway
user for the S3 interface. Then, create a subuser for the Swift interface.
See the `Admin Guide`_ for more details on user management.
Create a radosgw user for S3 access
------------------------------------
A ``radosgw`` user needs to be created and granted access. The command
``man radosgw-admin`` will provide information on additional command options.
To create the user, execute the following on the ``gateway host``::
sudo radosgw-admin user create --uid="testuser" --display-name="First User"
The output of the command will be something like the following::
{"user_id": "testuser",
"display_name": "First User",
"email": "",
"suspended": 0,
"max_buckets": 1000,
"auid": 0,
"subusers": [],
"keys": [
{ "user": "testuser",
"access_key": "I0PJDPCIYZ665MW88W9R",
"secret_key": "dxaXZ8U90SXydYzyS5ivamEP20hkLSUViiaR+ZDA"}],
"swift_keys": [],
"caps": [],
"op_mask": "read, write, delete",
"default_placement": "",
"placement_tags": [],
"bucket_quota": { "enabled": false,
"max_size_kb": -1,
"max_objects": -1},
"user_quota": { "enabled": false,
"max_size_kb": -1,
"max_objects": -1},
"temp_url_keys": []}
.. note:: The values of ``keys->access_key`` and ``keys->secret_key`` are
needed for access validation.
Create a Swift user
-------------------
A Swift subuser needs to be created if this kind of access is needed. Creating
a Swift user is a two step process. The first step is to create the user.
The second is to create the secret key.
Execute the following steps on the ``gateway host``:
Create the Swift user::
sudo radosgw-admin subuser create --uid=testuser --subuser=testuser:swift --access=full
The output will be something like the following::
{ "user_id": "testuser",
"display_name": "First User",
"email": "",
"suspended": 0,
"max_buckets": 1000,
"auid": 0,
"subusers": [
{ "id": "testuser:swift",
"permissions": "full-control"}],
"keys": [
{ "user": "testuser:swift",
"access_key": "3Y1LNW4Q6X0Y53A52DET",
"secret_key": ""},
{ "user": "testuser",
"access_key": "I0PJDPCIYZ665MW88W9R",
"secret_key": "dxaXZ8U90SXydYzyS5ivamEP20hkLSUViiaR+ZDA"}],
"swift_keys": [],
"caps": [],
"op_mask": "read, write, delete",
"default_placement": "",

"max_objects": -1},
"user_quota": { "enabled": false,
"max_size_kb": -1,
"max_objects": -1},
"temp_url_keys": []}
Create the secret key::
sudo radosgw-admin key create --subuser=testuser:swift --key-type=swift --gen-secret
The output will be something like the following::
{ "user_id": "testuser",
"display_name": "First User",
"email": "",
"suspended": 0,
"max_buckets": 1000,
"auid": 0,
"subusers": [

"secret_key": "dxaXZ8U90SXydYzyS5ivamEP20hkLSUViiaR+ZDA"}],
"swift_keys": [
{ "user": "testuser:swift",
"secret_key": "244+fz2gSqoHwR3lYtSbIyomyPHf3i7rgSJrF\/IA"}],

"max_objects": -1},
"user_quota": { "enabled": false,
"max_size_kb": -1,
"max_objects": -1},
"temp_url_keys": []}
Access Verification
===================
You then need to verify if the created users are able to access the gateway.
Test S3 access
--------------
You need to write and run a Python test script for verifying S3 access. The S3
access test script will connect to the ``radosgw``, create a new bucket and list
all buckets. The values for ``aws_access_key_id`` and ``aws_secret_access_key``
are taken from the values of ``access_key`` and ``secret_key`` returned by the
``radosgw_admin`` command.
Execute the following steps:
#. You will need to install the ``python-boto`` package.
For Debian-based distros, run::
sudo apt-get install python-boto
For RPM-based distros, run::
sudo yum install python-boto
#. Create the Python script::
vi s3test.py
#. Add the following contents to the file::
import boto
import boto.s3.connection
access_key = 'I0PJDPCIYZ665MW88W9R'
secret_key = 'dxaXZ8U90SXydYzyS5ivamEP20hkLSUViiaR+ZDA'
conn = boto.connect_s3(
aws_access_key_id = access_key,
aws_secret_access_key = secret_key,
host = '{hostname}',
is_secure=False,
calling_format = boto.s3.connection.OrdinaryCallingFormat(),
)
bucket = conn.create_bucket('my-new-bucket')
for bucket in conn.get_all_buckets():
print "{name}\t{created}".format(
name = bucket.name,
created = bucket.creation_date,
)
Replace ``{hostname}`` with the hostname of the host where you have
configured the gateway service i.e., the ``gateway host``.
#. Run the script::
python s3test.py
The output will be something like the following::
my-new-bucket 2015-02-16T17:09:10.000Z
Test swift access
-----------------
Swift access can be verified via the ``swift`` command line client. The command
``man swift`` will provide more information on available command line options.
To install ``swift`` client, execute the following:
For Debian-based distros::
sudo apt-get install python-setuptools
sudo easy_install pip
sudo pip install --upgrade setuptools
sudo pip install --upgrade python-swiftclient
For RPM-based distros::
sudo yum install python-setuptools
sudo easy_install pip
sudo pip install --upgrade setuptools
sudo pip install --upgrade python-swiftclient
To test swift access, execute the following::
swift -A http://{IP ADDRESS}/auth/1.0 -U testuser:swift -K ‘{swift_secret_key}’ list
Replace ``{IP ADDRESS}`` with the public IP address of the gateway server and
``{swift_secret_key}`` with its value from the output of
``radosgw-admin key create`` command executed for the ``swift`` user.
For example::
swift -A http://10.19.143.116/auth/1.0 -U testuser:swift -K ‘244+fz2gSqoHwR3lYtSbIyomyPHf3i7rgSJrF/IA’ list
The output should be::

Regions
=======
``rgw verify ssl``

a global namespace via the notion of regions. A region defines the geographic
location of one or more Ceph Object Gateway instances within one or more zones.
:Description: Verify SSL certificates while making requests.
:Type: Boolean
:Default: ``true``
Configuring regions differs from typical configuration procedures, because not
all of the settings end up in a Ceph configuration file. In Ceph v0.67 and
beyond, you can list regions, get a region configuration and set a region
configuration.
Multisite Settings
==================
List Regions
------------
A Ceph cluster contains a list of regions. To list the regions, execute::
sudo radosgw-admin region list
The ``radosgw-admin`` returns a JSON formatted list of regions.
.. code-block:: javascript
{ "default_info": { "default_region": "default"},
"regions": [
"default"]}
Get a Region Map
----------------
To list the details of each region, execute::
sudo radosgw-admin region-map get
.. note:: If you receive a ``failed to read region map`` error, run
``sudo radosgw-admin region-map update`` first.
Get a Region
------------
To view the configuration of a region, execute::
radosgw-admin region get [--rgw-region=<region>]
The ``default`` region looks like this:
.. code-block:: javascript
{"name": "default",
"api_name": "",
"is_master": "true",
"endpoints": [],
"hostnames": [],
"master_zone": "",
"zones": [
{"name": "default",
"endpoints": [],
"log_meta": "false",
"log_data": "false"}
],
"placement_targets": [
{"name": "default-placement",
"tags": [] }],
"default_placement": "default-placement"}
Set a Region
------------
Defining a region consists of creating a JSON object, specifying at least the
required settings:
#. ``name``: The name of the region. Required.
#. ``api_name``: The API name for the region. Optional.
#. ``is_master``: Determines if the region is the master region. Required.
**note:** You can only have one master region.
#. ``endpoints``: A list of all the endpoints in the region. For example,
you may use multiple domain names to refer to the same region. Remember to
escape the forward slashes (``\/``). You may also specify a
port (``fqdn:port``) for each endpoint. Optional.
#. ``hostnames``: A list of all the hostnames in the region. For example,
you may use multiple domain names to refer to the same region. Optional.
The ``rgw dns name`` setting will automatically be included in this list.
You should restart the ``radosgw`` daemon(s) after changing this setting.
#. ``master_zone``: The master zone for the region. Optional. Uses the default
zone if not specified. **note:** You can only have one master zone per
region.
#. ``zones``: A list of all zones within the region. Each zone has a
name (required), a list of endpoints (optional), and whether or not the
gateway will log metadata and data operations (false by default).
#. ``placement_targets``: A list of placement targets (optional). Each
placement target contains a name (required) for the placement target
and a list of tags (optional) so that only users with the tag can use
the placement target (i.e., the user's ``placement_tags`` field in the
user info).
#. ``default_placement``: The default placement target for the object
index and object data. Set to ``default-placement`` by default. You
may also set a per-user default placement in the user info for each
user.
To set a region, create a JSON object consisting of the required fields, save
the object to a file (e.g., ``region.json``); then, execute the following
command::
sudo radosgw-admin region set --infile region.json
Where ``region.json`` is the JSON file you created.
.. important:: The ``default`` region ``is_master`` setting is ``true`` by
default. If you create a new region and want to make it the master region,
you must either set the ``default`` region ``is_master`` setting to
``false``, or delete the ``default`` region.
Finally, update the map. ::
sudo radosgw-admin region-map update
Set a Region Map
----------------
Setting a region map consists of creating a JSON object consisting of one or more
regions, and setting the ``master_region`` for the cluster. Each region in the
region map consists of a key/value pair, where the ``key`` setting is equivalent to
the ``name`` setting for an individual region configuration, and the ``val`` is
a JSON object consisting of an individual region configuration.
You may only have one region with ``is_master`` equal to ``true``, and it must be
specified as the ``master_region`` at the end of the region map. The following
JSON object is an example of a default region map.
.. code-block:: javascript
{ "regions": [
{ "key": "default",
"val": { "name": "default",
"api_name": "",
"is_master": "true",
"endpoints": [],
"hostnames": [],
"master_zone": "",
"zones": [
{ "name": "default",
"endpoints": [],
"log_meta": "false",
"log_data": "false"}],
"placement_targets": [
{ "name": "default-placement",
"tags": []}],
"default_placement": "default-placement"
}
}
],
"master_region": "default"
}
To set a region map, execute the following::
sudo radosgw-admin region-map set --infile regionmap.json
Where ``regionmap.json`` is the JSON file you created. Ensure that you have
zones created for the ones specified in the region map. Finally, update the map.
::
sudo radosgw-admin regionmap update
Zones
=====
In Ceph v0.67 and beyond, Ceph Object Gateway supports the notion of zones. A
zone defines a logical group consisting of one or more Ceph Object Gateway
instances.
Configuring zones differs from typical configuration procedures, because not
all of the settings end up in a Ceph configuration file. In Ceph v0.67 and
beyond, you can list zones, get a zone configuration and set a zone
configuration.
List Zones
----------
To list the zones in a cluster, execute::
sudo radosgw-admin zone list
Get a Zone
----------
To get the configuration of a zone, execute::
sudo radosgw-admin zone get [--rgw-zone=<zone>]
The ``default`` zone looks like this:
.. code-block:: javascript
{ "domain_root": ".rgw",
"control_pool": ".rgw.control",
"gc_pool": ".rgw.gc",
"log_pool": ".log",
"intent_log_pool": ".intent-log",
"usage_log_pool": ".usage",
"user_keys_pool": ".users",
"user_email_pool": ".users.email",
"user_swift_pool": ".users.swift",

"placement_pools": [
{ "key": "default-placement",
"val": { "index_pool": ".rgw.buckets.index",
"data_pool": ".rgw.buckets"}
}
]
}
Set a Zone
----------
Configuring a zone involves specifying a series of Ceph Object Gateway pools.
For consistency, we recommend using a pool prefix that is
the same as the zone name. See `Pools`_ for details of configuring pools.
To set a zone, create a JSON object consisting of the pools, save
the object to a file (e.g., ``zone.json``); then, execute the following
command, replacing ``{zone-name}`` with the name of the zone::
sudo radosgw-admin zone set --rgw-zone={zone-name} --infile zone.json
Where ``zone.json`` is the JSON file you created.

Pools
=====
Ceph zones map to a series of Ceph Storage Cluster pools.
.. topic:: Manually Created Pools vs. Generated Pools
If you provide write capabilities to the user key for your Ceph Object
Gateway, the gateway has the ability to create pools automatically. This
is convenient, but the Ceph Object Storage Cluster uses the default
values for the number of placement groups (which may not be ideal) or the
values you specified in your Ceph configuration file. If you allow the
Ceph Object Gateway to create pools automatically, ensure that you have
reasonable defaults for the number of placement groups. See
`Pool Configuration`_ for details. See `Cluster Pools`_ for details on
creating pools.
The default pools for the Ceph Object Gateway's default zone include:
- ``.rgw``
- ``.rgw.control``
- ``.rgw.gc``
- ``.log``
- ``.intent-log``
- ``.usage``
- ``.users``
- ``.users.email``
- ``.users.swift``
- ``.users.uid``
You have significant discretion in determining how you want a zone to access
pools. You can create pools on a per zone basis, or use the same pools for
multiple zones. As a best practice, we recommend having a separate set of pools
for your master zone and your secondary zones in each region. When creating
pools for a specific zone, consider prepending the region name and zone name to
the default pool names. For example:
- ``.region1-zone1.domain.rgw``
- ``.region1-zone1.rgw.control``
- ``.region1-zone1.rgw.gc``
- ``.region1-zone1.log``
- ``.region1-zone1.intent-log``
- ``.region1-zone1.usage``
- ``.region1-zone1.users``
- ``.region1-zone1.users.email``
- ``.region1-zone1.users.swift``
- ``.region1-zone1.users.uid``
:Description: If there are other zones in the realm to sync from, spawn threads
to handle the sync of data and metadata.
:Type: Boolean
:Default: ``true``
Ceph Object Gateways store data for the bucket index (``index_pool``) and bucket
data (``data_pool``) in placement pools. These may overlap--i.e., you may use
the same pool for the index and the data. The index pool for default
placement is ``.rgw.buckets.index`` and for the data pool for default placement
is ``.rgw.buckets``. See `Zones`_ for details on specifying pools in a zone
configuration.

Configuring Federated Gateways
================================
.. versionadded:: 0.67 Dumpling
In Ceph version 0.67 Dumpling and beyond, you may configure each :term:`Ceph
Object Gateway` to participate in a federated architecture, with multiple
regions, and with multiple zones for a region.
- **Region**: A region represents a *logical* geographic area and contains one
or more zones. A cluster with multiple regions must specify a master region.
- **Zone**: A zone is a *logical* grouping of one or more Ceph Object Gateway
instance(s). A region has a master zone that processes client requests.
.. important:: Only write objects to the master zone in a region. You may read
objects from secondary zones. Currently, the Gateway does not prevent you
from writing to a secondary zone, but **DON'T DO IT**.
Background
==========
When you deploy a :term:`Ceph Object Store` service that spans geographical
locales, configuring Ceph Object Gateway regions and metadata synchronization
agents enables the service to maintain a global namespace, even though Ceph
Object Gateway instances run in different geographic locales and potentially on
different Ceph Storage Clusters. When you separate one or more Ceph Object
Gateway instances within a region into separate logical containers to maintain
an extra copy (or copies) of the data, configuring Ceph Object Gateway zones and
data synchronization agents enables the service to maintain one or more
copy(ies) of the master zone's data. Extra copies of the data are important for
failover, backup and disaster recovery.
You may deploy a single Ceph Storage Cluster with a federated architecture if
you have low latency network connections (this isn't recommended). You may also
deploy one Ceph Storage Cluster per region with a separate set of pools for
each zone (typical). You may also deploy a separate Ceph Storage Cluster for
each zone if your requirements and resources warrant this level of redundancy.
About this Guide
================
In the following sections, we will demonstrate how to configure a federated
cluster in two logical steps:
- **Configure a Master Region:** This section of the guide describes how to
set up a region with multiple zones, and how to synchronize data between the
master zone and the secondary zone(s) within the master region.
- **Configure a Secondary Region:** This section of the guide describes how
to repeat the section on setting up a master region and multiple zones so
that you have two regions with intra-zone synchronization in each region.
Finally, you will learn how to set up a metadata synchronization agent so
that you can maintain a global namespace for the regions in your cluster.
Configure a Master Region
=========================
This section provides an exemplary procedure for setting up a region, and two
zones within the region. The cluster will comprise two gateway daemon
instances--one per zone. This region will serve as the master region.
Naming for the Master Region
----------------------------
Before configuring the cluster, defining region, zone and instance names will
help you manage your cluster. Let's assume the region represents the United
States, and we refer to it by its standard abbreviation.
- United States: ``us``
Let's assume the zones represent the Eastern and Western United States. For
continuity, our naming convention will use ``{region name}-{zone name}`` format,
but you can use any naming convention you prefer.
- United States, East Region: ``us-east``
- United States, West Region: ``us-west``
Finally, let's assume that zones may have more than one Ceph Object Gateway
instance per zone. For continuity, our naming convention will use
``{region name}-{zone name}-{instance}`` format, but you can use any naming
convention you prefer.
- United States Region, Master Zone, Instance 1: ``us-east-1``
- United States Region, Secondary Zone, Instance 1: ``us-west-1``
Create Pools
------------
You may have a Ceph Storage Cluster for the entire region or a Ceph Storage
Cluster for each zone.
For continuity, our naming convention will use ``{region name}-{zone name}``
format prepended to the pool name, but you can use any naming convention you
prefer. For example:
- ``.us-east.rgw.root``
- ``.us-east.rgw.control``
- ``.us-east.rgw.gc``
- ``.us-east.rgw.buckets``
- ``.us-east.rgw.buckets.index``
- ``.us-east.rgw.buckets.extra``
- ``.us-east.log``
- ``.us-east.intent-log``
- ``.us-east.usage``
- ``.us-east.users``
- ``.us-east.users.email``
- ``.us-east.users.swift``
- ``.us-east.users.uid``
|
- ``.us-west.rgw.root``
- ``.us-west.rgw.control``
- ``.us-west.rgw.gc``
- ``.us-west.rgw.buckets``
- ``.us-west.rgw.buckets.index``
- ``.us-west.rgw.buckets.extra``
- ``.us-west.log``
- ``.us-west.intent-log``
- ``.us-west.usage``
- ``.us-west.users``
- ``.us-west.users.email``
- ``.us-west.users.swift``
- ``.us-west.users.uid``
See `Configuration Reference - Pools`_ for details on the default pools for
gateways. See `Pools`_ for details on creating pools. Execute the following
to create a pool::
ceph osd pool create {poolname} {pg-num} {pgp-num} {replicated | erasure} [{erasure-code-profile}] {ruleset-name} {ruleset-number}
.. tip:: When adding a large number of pools, it may take some time for your
cluster to return to a ``active + clean`` state.
.. topic:: CRUSH Maps
When deploying a Ceph Storage Cluster for the entire region, consider
using a CRUSH rule for the zone such that you do NOT have overlapping
failure domains. See `CRUSH Map`_ for details.
Ceph supports multiple CRUSH hierarchies and CRUSH rulesets, enabling
great flexibility in the way you configure your gateway. Pools such
as ``rgw.buckets.index`` may benefit from a modestly sized pool of SSDs
for fast performance. Backing storage may benefit from the increased economy
of erasure-coded storage, and/or the improved performance from cache tiering.
When you have completed this step, execute the following to ensure that
you have created all of the foregoing pools::
rados lspools
Create a Keyring
----------------
Each instance must have a user name and key to communicate with a Ceph Storage
Cluster. In the following steps, we use an admin node to create a keyring.
Then, we create a client user name and key for each instance. Next, we add the
keys to the Ceph Storage Cluster(s). Finally, we distribute the key ring to
each node containing an instance.
#. Create a keyring. ::
sudo ceph-authtool --create-keyring /etc/ceph/ceph.client.radosgw.keyring
sudo chmod +r /etc/ceph/ceph.client.radosgw.keyring
#. Generate a Ceph Object Gateway user name and key for each instance. ::
sudo ceph-authtool /etc/ceph/ceph.client.radosgw.keyring -n client.radosgw.us-east-1 --gen-key
sudo ceph-authtool /etc/ceph/ceph.client.radosgw.keyring -n client.radosgw.us-west-1 --gen-key
#. Add capabilities to each key. See `Configuration Reference - Pools`_ for details
on the effect of write permissions for the monitor and creating pools. ::
sudo ceph-authtool -n client.radosgw.us-east-1 --cap osd 'allow rwx' --cap mon 'allow rwx' /etc/ceph/ceph.client.radosgw.keyring
sudo ceph-authtool -n client.radosgw.us-west-1 --cap osd 'allow rwx' --cap mon 'allow rwx' /etc/ceph/ceph.client.radosgw.keyring
#. Once you have created a keyring and key to enable the Ceph Object Gateway
with access to the Ceph Storage Cluster, add each key as an entry to your
Ceph Storage Cluster(s). For example::
sudo ceph -k /etc/ceph/ceph.client.admin.keyring auth add client.radosgw.us-east-1 -i /etc/ceph/ceph.client.radosgw.keyring
sudo ceph -k /etc/ceph/ceph.client.admin.keyring auth add client.radosgw.us-west-1 -i /etc/ceph/ceph.client.radosgw.keyring
.. note:: When you use this procedure to configure the secondary region,
replace ``us-`` with ``eu-``. You will have a total of four users **after**
you create the master region and the secondary region.
Install Apache/FastCGI
----------------------
For each :term:`Ceph Node` that runs a :term:`Ceph Object Gateway` daemon
instance, you must install Apache, FastCGI, the Ceph Object Gateway daemon
(``radosgw``) and the Ceph Object Gateway Sync Agent (``radosgw-agent``).
See `Install Ceph Object Gateway`_ for details.
Create Data Directories
-----------------------
Create data directories for each daemon instance on their respective
hosts. ::
ssh {us-east-1}
sudo mkdir -p /var/lib/ceph/radosgw/ceph-radosgw.us-east-1
ssh {us-west-1}
sudo mkdir -p /var/lib/ceph/radosgw/ceph-radosgw.us-west-1
.. note:: When you use this procedure to configure the secondary region,
replace ``us-`` with ``eu-``. You will have a total of four data directories
**after** you create the master region and the secondary region.
Create a Gateway Configuration
------------------------------
For each instance, create an Ceph Object Gateway configuration file under the
``/etc/apache2/sites-available`` directory on the host(s) where you installed
the Ceph Object Gateway daemon(s). See below for an exemplary embodiment of a
gateway configuration as discussed in the following text.
.. literalinclude:: rgw.conf
:language: ini
#. Replace the ``/{path}/{socket-name}`` entry with path to the socket and
the socket name. For example,
``/var/run/ceph/client.radosgw.us-east-1.sock``. Ensure that you use the
same path and socket name in your ``ceph.conf`` entry.
#. Replace the ``{fqdn}`` entry with the fully-qualified domain name of the
server.
#. Replace the ``{email.address}`` entry with the email address for the
server administrator.
#. Add a ``ServerAlias`` if you wish to use S3-style subdomains
(of course you do).
#. Save the configuration to a file (e.g., ``rgw-us-east.conf``).
Repeat the process for the secondary zone (e.g., ``rgw-us-west.conf``).
.. note:: When you use this procedure to configure the secondary region,
replace ``us-`` with ``eu-``. You will have a total of four gateway
configuration files on the respective nodes **after**
you create the master region and the secondary region.
Finally, if you enabled SSL, make sure that you set the port to your SSL port
(usually 443) and your configuration file includes the following::
SSLEngine on
SSLCertificateFile /etc/apache2/ssl/apache.crt
SSLCertificateKeyFile /etc/apache2/ssl/apache.key
SetEnv SERVER_PORT_SECURE 443
Enable the Configuration
------------------------
For each instance, enable the gateway configuration and disable the
default site.
#. Enable the site for the gateway configuration. ::
sudo a2ensite {rgw-conf-filename}
#. Disable the default site. ::
sudo a2dissite default
.. note:: Failure to disable the default site can lead to problems.
Add a FastCGI Script
--------------------
FastCGI requires a script for each Ceph Object Gateway instance to
enable the S3-compatible interface. To create the script, execute
the following procedures.
#. Go to the ``/var/www`` directory. ::
cd /var/www
#. Open an editor with the file name ``s3gw.fcgi``. **Note:** The configuration
file specifies this filename. ::
sudo vim s3gw.fcgi
#. Add a shell script with ``exec`` and the path to the gateway binary,
the path to the Ceph configuration file, and the user name (``-n``;
the same user name created in step 2 of `Create a Keyring`_.
Copy the following into the editor. ::
#!/bin/sh
exec /usr/bin/radosgw -c /etc/ceph/ceph.conf -n client.radosgw.{ID}
For example::
#!/bin/sh
exec /usr/bin/radosgw -c /etc/ceph/ceph.conf -n client.radosgw.us-east-1
#. Save the file.
#. Change the permissions on the file so that it is executable. ::
sudo chmod +x s3gw.fcgi
Repeat the process for the secondary zone.
.. note:: When you use this procedure to configure the secondary region,
replace ``us-`` with ``eu-``. You will have a total of four FastCGI scripts
**after** you create the master region and the secondary region.
Add Instances to Ceph Config File
---------------------------------
On an admin node, add an entry for each instance in the Ceph configuration file
for your Ceph Storage Cluster(s). For example::
[global]
rgw region root pool = .us.rgw.root # Deprecated in Jewel
rgw zonegroup root pool = .us.rgw.root # From Jewel
[client.radosgw.us-east-1]
rgw region = us
rgw zone = us-east
rgw zone root pool = .us-east.rgw.root
keyring = /etc/ceph/ceph.client.radosgw.keyring
rgw dns name = {hostname}
rgw socket path = /var/run/ceph/$name.sock
host = {host-name}
[client.radosgw.us-west-1]
rgw region = us
rgw zone = us-west
rgw zone root pool = .us-west.rgw.root
keyring = /etc/ceph/ceph.client.radosgw.keyring
rgw dns name = {hostname}
rgw socket path = /var/run/ceph/$name.sock
host = {host-name}
Then, update each :term:`Ceph Node` with the updated Ceph configuration
file. For example::
ceph-deploy --overwrite-conf config push {node1} {node2} {nodex}
.. note:: When you use this procedure to configure the secondary region,
replace ``us`` with ``eu`` for the name, region, pools and zones.
You will have a total of four entries **after**
you create the master region and the secondary region.
Create a Region
---------------
#. Configure a region infile called ``us.json`` for the ``us`` region.
Copy the contents of the following example to a text editor. Set
``is_master`` to ``true``. Replace ``{fqdn}`` with the fully-qualified
domain name of the endpoint. It will specify a master zone as ``us-east``
and list it in the ``zones`` list along with the ``us-west`` zone.
See `Configuration Reference - Regions`_ for details.::
{ "name": "us",
"api_name": "us",
"is_master": "true",
"endpoints": [
"http:\/\/{fqdn}:80\/"],
"master_zone": "us-east",
"zones": [
{ "name": "us-east",
"endpoints": [
"http:\/\/{fqdn}:80\/"],
"log_meta": "true",
"log_data": "true"},
{ "name": "us-west",
"endpoints": [
"http:\/\/{fqdn}:80\/"],
"log_meta": "true",
"log_data": "true"}],
"placement_targets": [
{
"name": "default-placement",
"tags": []
}
],
"default_placement": "default-placement"}
#. Create the ``us`` region using the ``us.json`` infile you just
created. ::
radosgw-admin region set --infile us.json --name client.radosgw.us-east-1
#. Delete the default region (if it exists). ::
rados -p .us.rgw.root rm region_info.default
#. Set the ``us`` region as the default region. ::
radosgw-admin region default --rgw-region=us --name client.radosgw.us-east-1
Only one region can be the default region for a cluster.
#. Update the region map. ::
radosgw-admin regionmap update --name client.radosgw.us-east-1
If you use different Ceph Storage Cluster instances for regions, you should
repeat steps 2, 4 and 5 in by executing them with ``--name
client.radosgw-us-west-1``. You may also export the region map from the initial
gateway instance and import it followed by updating the region map.
.. note:: When you use this procedure to configure the secondary region,
replace ``us`` with ``eu``. You will have a total of two regions **after**
you create the master region and the secondary region.
Create Zones
------------
#. Configure a zone infile called ``us-east.json`` for the
``us-east`` zone.
Copy the contents of the following example to a text editor.
This configuration uses pool names prepended with the region name and
zone name. See `Configuration Reference - Pools`_ for additional details on
gateway pools. See `Configuration Reference - Zones`_ for additional
details on zones. ::
{ "domain_root": ".us-east.domain.rgw",
"control_pool": ".us-east.rgw.control",
"gc_pool": ".us-east.rgw.gc",
"log_pool": ".us-east.log",
"intent_log_pool": ".us-east.intent-log",
"usage_log_pool": ".us-east.usage",
"user_keys_pool": ".us-east.users",
"user_email_pool": ".us-east.users.email",
"user_swift_pool": ".us-east.users.swift",
"user_uid_pool": ".us-east.users.uid",
"system_key": { "access_key": "", "secret_key": ""},
"placement_pools": [
{ "key": "default-placement",
"val": { "index_pool": ".us-east.rgw.buckets.index",
"data_pool": ".us-east.rgw.buckets"}
}
]
}
#. Add the ``us-east`` zone using the ``us-east.json`` infile you
just created in both the east and west pools by specifying their respective
user names (i.e., ``--name``). ::
radosgw-admin zone set --rgw-zone=us-east --infile us-east.json --name client.radosgw.us-east-1
radosgw-admin zone set --rgw-zone=us-east --infile us-east.json --name client.radosgw.us-west-1
Repeat step 1 to create a zone infile for ``us-west``. Then add the zone
using the ``us-west.json`` infile in both the east and west pools by
specifying their respective user names (i.e., ``--name``). ::
radosgw-admin zone set --rgw-zone=us-west --infile us-west.json --name client.radosgw.us-east-1
radosgw-admin zone set --rgw-zone=us-west --infile us-west.json --name client.radosgw.us-west-1
#. Delete the default zone (if it exists). ::
rados -p .us-east.rgw.root rm zone_info.default
rados -p .us-west.rgw.root rm zone_info.default
#. Update the region map. ::
radosgw-admin regionmap update --name client.radosgw.us-east-1
.. note:: When you use this procedure to configure the secondary region,
replace ``us-`` with ``eu-``. You will have a total of four zones **after**
you create the master zone and the secondary zone in each region.
Create Zone Users
-----------------
Ceph Object Gateway stores zone users in the zone pools. So you must create zone
users after configuring the zones. Copy the ``access_key`` and ``secret_key``
fields for each user so you can update your zone configuration once you complete
this step. ::
radosgw-admin user create --uid="us-east" --display-name="Region-US Zone-East" --name client.radosgw.us-east-1 --system
radosgw-admin user create --uid="us-west" --display-name="Region-US Zone-West" --name client.radosgw.us-west-1 --system
.. note:: When you use this procedure to configure the secondary region,
replace ``us-`` with ``eu-``. You will have a total of four zone users
**after** you create the master region and the secondary region and their
zones. These users are different from the users created in `Create a
Keyring`_.
Update Zone Configurations
--------------------------
You must update the zone configuration with zone users so that
the synchronization agents can authenticate with the zones.
#. Open your ``us-east.json`` zone configuration file and paste the contents of
the ``access_key`` and ``secret_key`` fields from the step of creating
zone users into the ``system_key`` field of your zone configuration
infile. ::
{ "domain_root": ".us-east.domain.rgw",
"control_pool": ".us-east.rgw.control",
"gc_pool": ".us-east.rgw.gc",
"log_pool": ".us-east.log",
"intent_log_pool": ".us-east.intent-log",
"usage_log_pool": ".us-east.usage",
"user_keys_pool": ".us-east.users",
"user_email_pool": ".us-east.users.email",
"user_swift_pool": ".us-east.users.swift",
"user_uid_pool": ".us-east.users.uid",
"system_key": {
"access_key": "{paste-access_key-here}",
"secret_key": "{paste-secret_key-here}"
},
"placement_pools": [
{ "key": "default-placement",
"val": { "index_pool": ".us-east.rgw.buckets.index",
"data_pool": ".us-east.rgw.buckets"}
}
]
}
#. Save the ``us-east.json`` file. Then, update your zone configuration. ::
radosgw-admin zone set --rgw-zone=us-east --infile us-east.json --name client.radosgw.us-east-1
radosgw-admin zone set --rgw-zone=us-east --infile us-east.json --name client.radosgw.us-west-1
#. Repeat step 1 to update the zone infile for ``us-west``. Then, update
your zone configuration. ::
radosgw-admin zone set --rgw-zone=us-west --infile us-west.json --name client.radosgw.us-east-1
radosgw-admin zone set --rgw-zone=us-west --infile us-west.json --name client.radosgw.us-west-1
.. note:: When you use this procedure to configure the secondary region,
replace ``us-`` with ``eu-``. You will have a total of four zones **after**
you create the master zone and the secondary zone in each region.
Restart Services
----------------
Once you have redeployed your Ceph configuration files, we recommend restarting
your Ceph Storage Cluster(s) and Apache instances.
For Ubuntu, use the following on each :term:`Ceph Node`::
sudo restart ceph-all
For Red Hat/CentOS, use the following::
sudo /etc/init.d/ceph restart
To ensure that all components have reloaded their configurations, for each
gateway instance we recommend restarting the ``apache2`` service. For example::
sudo service apache2 restart
Start Gateway Instances
-----------------------
Start up the ``radosgw`` service. ::
sudo /etc/init.d/radosgw start
If you are running multiple instances on the same host, you must specify the
user name. ::
sudo /etc/init.d/radosgw start --name client.radosgw.us-east-1
Open a browser and check the endpoints for each zone. A simple HTTP request
to the domain name should return the following:
.. code-block:: xml
<ListAllMyBucketsResult xmlns="http://s3.amazonaws.com/doc/2006-03-01/">
<Owner>
<ID>anonymous</ID>
<DisplayName/>
</Owner>
<Buckets/>
</ListAllMyBucketsResult>
Configure a Secondary Region
============================
This section provides an exemplary procedure for setting up a cluster with
multiple regions. Configuring a cluster that spans regions requires maintaining
a global namespace, so that there are no namespace clashes among object names
stored across in different regions.
This section extends the procedure in `Configure a Master Region`_, but
changes the region name and modifies a few procedures. See the following
sections for details.
Naming for the Secondary Region
-------------------------------
Before configuring the cluster, defining region, zone and instance names will
help you manage your cluster. Let's assume the region represents the European
Union, and we refer to it by its standard abbreviation.
- European Union: ``eu``
Let's assume the zones represent the Eastern and Western European Union. For
continuity, our naming convention will use ``{region name}-{zone name}``
format, but you can use any naming convention you prefer.
- European Union, East Region: ``eu-east``
- European Union, West Region: ``eu-west``
Finally, let's assume that zones may have more than one Ceph Object Gateway
instance per zone. For continuity, our naming convention will use
``{region name}-{zone name}-{instance}`` format, but you can use any naming
convention you prefer.
- European Union Region, Master Zone, Instance 1: ``eu-east-1``
- European Union Region, Secondary Zone, Instance 1: ``eu-west-1``
Configuring a Secondary Region
------------------------------
Repeat the exemplary procedure of `Configure a Master Region`_
with the following differences:
#. Use `Naming for the Secondary Region`_ in lieu of `Naming for
the Master Region`_.
#. `Create Pools`_ using ``eu`` instead of ``us``.
#. `Create a Keyring`_ and the corresponding keys using ``eu`` instead of
``us``. You may use the same keyring if you desire, but ensure that you
create the keys on the Ceph Storage Cluster for that region (or region
and zone).
#. `Install Apache/FastCGI`_.
#. `Create Data Directories`_ using ``eu`` instead of ``us``.
#. `Create a Gateway Configuration`_ using ``eu`` instead of ``us`` for
the socket names.
#. `Enable the Configuration`_.
#. `Add a FastCGI Script`_ using ``eu`` instead of ``us`` for the user names.
#. `Add Instances to Ceph Config File`_ using ``eu`` instead of ``us`` for the
pool names.
#. `Create a Region`_ using ``eu`` instead of ``us``. Set ``is_master`` to
``false``. For consistency, create the master region in the secondary region
too. ::
radosgw-admin region set --infile us.json --name client.radosgw.eu-east-1
#. `Create Zones`_ using ``eu`` instead of ``us``. Ensure that you update the
user name (i.e., ``--name``) so that you create the zones in the correct
cluster.
#. `Update Zone Configurations`_ using ``eu`` instead of ``us``.
#. Create zones from master region in the secondary region. ::
radosgw-admin zone set --rgw-zone=us-east --infile us-east.json --name client.radosgw.eu-east-1
radosgw-admin zone set --rgw-zone=us-east --infile us-east.json --name client.radosgw.eu-west-1
radosgw-admin zone set --rgw-zone=us-west --infile us-west.json --name client.radosgw.eu-east-1
radosgw-admin zone set --rgw-zone=us-west --infile us-west.json --name client.radosgw.eu-west-1
#. Create zones from secondary region in the master region. ::
radosgw-admin zone set --rgw-zone=eu-east --infile eu-east.json --name client.radosgw.us-east-1
radosgw-admin zone set --rgw-zone=eu-east --infile eu-east.json --name client.radosgw.us-west-1
radosgw-admin zone set --rgw-zone=eu-west --infile eu-west.json --name client.radosgw.us-east-1
radosgw-admin zone set --rgw-zone=eu-west --infile eu-west.json --name client.radosgw.us-west-1
#. `Restart Services`_.
#. `Start Gateway Instances`_.
Multi-Site Data Replication
===========================
The data synchronization agent replicates the data of a master zone to a
secondary zone. The master zone of a region is the source for the secondary zone
of the region and it gets selected automatically.
.. image:: ../images/zone-sync.png
To configure the synchronization agent, retrieve the access key and secret for
the source and destination, and the destination URL and port.
You may use ``radosgw-admin zone list`` to get a list of zone names. You
may use ``radosgw-admin zone get`` to identify the key and secret for the
zone. You may refer to the gateway configuration file you created under
`Create a Gateway Configuration`_ to identify the port number.
You only need the hostname and port for a single instance (assuming all
gateway instances in a region/zone access the same Ceph Storage Cluster).
Specify these values in a configuration file
(e.g., ``cluster-data-sync.conf``), and include a ``log_file`` name.
For example:
.. code-block:: ini
src_access_key: {source-access-key}
src_secret_key: {source-secret-key}
destination: https://zone-name.fqdn.com:port
dest_access_key: {destination-access-key}
dest_secret_key: {destination-secret-key}
log_file: {log.filename}
A concrete example may look like this:
.. code-block:: ini
src_access_key: DG8RE354EFPZBICHIAF0
src_secret_key: i3U0HiRP8CXaBWrcF8bbh6CbsxGYuPPwRkixfFSb
destination: https://us-west.storage.net:80
dest_access_key: U60RFI6B08F32T2PD30G
dest_secret_key: W3HuUor7Gl1Ee93pA2pq2wFk1JMQ7hTrSDecYExl
log_file: /var/log/radosgw/radosgw-sync-us-east-west.log
To activate the data synchronization agent, open a terminal and
execute the following::
radosgw-agent -c region-data-sync.conf
When the synchronization agent is running, you should see output
indicating that the agent is synchronizing shards of data. ::
INFO:radosgw_agent.sync:Starting incremental sync
INFO:radosgw_agent.worker:17910 is processing shard number 0
INFO:radosgw_agent.worker:shard 0 has 0 entries after ''
INFO:radosgw_agent.worker:finished processing shard 0
INFO:radosgw_agent.worker:17910 is processing shard number 1
INFO:radosgw_agent.sync:1/64 shards processed
INFO:radosgw_agent.worker:shard 1 has 0 entries after ''
INFO:radosgw_agent.worker:finished processing shard 1
INFO:radosgw_agent.sync:2/64 shards processed
...
.. note:: You must have an agent for each source-destination pair.
Inter-Region Metadata Replication
=================================
The data synchronization agent replicates the metadata of master zone in the
master region to a master zone in a secondary region. Metadata consists of
gateway users and buckets, but not the objects within the buckets--ensuring a
unified namespace across the cluster. The master zone of the master region is
the source for the master zone of the secondary region and it gets selected
automatically.
.. image:: ../images/region-sync.png
:align: center
Follow the same steps in `Multi-Site Data Replication`_ by specifying the master
zone of the master region as the source zone and the master zone of the
secondary region as the secondary zone. When activating the ``radosgw-agent``,
specify ``--metadata-only`` so that it only copies metadata. For example::
radosgw-agent -c inter-region-data-sync.conf --metadata-only
Once you have completed the foregoing procedure, you should have a cluster
consisting of a master region (``us``) and a secondary region (``eu``) where
there is a unified namespace between the two regions.

Pools
=====
We recommend using the `Ceph Placement Group’s per Pool
Calculator <http://ceph.com/pgcalc/>`__ to calculate a
suitable number of placement groups for the pools the ``ceph-radosgw``
daemon will create. Set the calculated values as defaults in your Ceph
configuration file. For example:
::
osd pool default pg num = 50
osd pool default pgp num = 50
.. note:: Make this change to the Ceph configuration file on your
storage cluster; then, either make a runtime change to the
configuration so that it will use those defaults when the gateway
instance creates the pools.
Alternatively, create the pools manually. See
`Pools <http://docs.ceph.com/docs/master/rados/operations/pools/#pools>`__
for details on creating pools.
Pool names particular to a zone follow the naming convention
``{zone-name}.pool-name``. For example, a zone named ``us-east`` will
have the following pools:
- ``.rgw.root``
- ``us-east.rgw.control``
- ``us-east.rgw.data.root``
- ``us-east.rgw.gc``
- ``us-east.rgw.log``
- ``us-east.rgw.intent-log``
- ``us-east.rgw.usage``

- ``us-east.rgw.users.swift``
- ``us-east.rgw.users.uid``

===
NFS
===
.. versionadded:: Jewel
Ceph Object Gateway namespaces can now be exported over file-based
access protocols such as NFSv3 and NFSv4, alongside traditional HTTP access
protocols (S3 and Swift).
In particular, the Ceph Object Gateway can now be configured to
provide file-based access when embedded in the NFS-Ganesha NFS server.
librgw
======
The librgw.so shared library (Unix) provides a loadable interface to
Ceph Object Gateway services, and instantiates a full Ceph Object Gateway
instance on initialization.
In turn, librgw.so exports rgw_file, a stateful API for file-oriented
access to RGW buckets and objects. The API is general, but its design
is strongly influenced by the File System Abstraction Layer (FSAL) API
of NFS-Ganesha, for which it has been primarily designed.
A set of Python bindings is also provided.
Namespace Conventions
=====================
The implementation conforms to Amazon Web Services (AWS) hierarchical
namespace conventions which map UNIX-style path names onto S3 buckets
and objects.
The top level of the attached namespace consists of S3 buckets,
represented as NFS directories. Files and directories subordinate to
buckets are each represented as objects, following S3 prefix and
delimiter conventions, with '/' being the only supported path
delimiter [#]_.
For example, if an NFS client has mounted an RGW namespace at "/nfs",
then a file "/nfs/mybucket/www/index.html" in the NFS namespace
corresponds to an RGW object "www/index.html" in a bucket/container
"mybucket."
Although it is generally invisible to clients, the NFS namespace is
assembled through concatenation of the corresponding paths implied by
the objects in the namespace. Leaf objects, whether files or
directories, will always be materialized in an RGW object of the
corresponding key name, "<name>" if a file, "<name>/" if a directory.
Non-leaf directories (e.g., "www" above) might only be implied by
their appearance in the names of one or more leaf objects. Directories
created within NFS or directly operated on by an NFS client (e.g., via
an attribute-setting operation such as chown or chmod) always have a
leaf object representation used to store materialized attributes such
as Unix ownership and permissions.
Supported Operations
====================
The RGW NFS interface supports most operations on files and
directories, with the following restrictions:
- Links, including symlinks, are not supported
- NFS ACLs are not supported
+ Unix user and group ownership and permissions *are* supported
- Directories may not be moved/renamed
+ files may be moved between directories
- Only full, sequential *write* i/o is supported
+ i.e., write operations are constrained to be **uploads**
+ many typical i/o operations such as editing files in place will necessarily fail as they perform non-sequential stores
+ some file utilities *apparently* writing sequentially (e.g., some versions of GNU tar) may fail due to infrequent non-sequential stores
+ When mounting via NFS, sequential application i/o can generally be constrained to be written sequentially to the NFS server via a synchronous mount option (e.g. -osync in Linux)
+ NFS clients which cannot mount synchronously (e.g., MS Windows) will not be able to upload files
Security
========
The RGW NFS interface provides a hybrid security model with the
following characteristics:
- NFS protocol security is provided by the NFS-Ganesha server, as negotiated by the NFS server and clients
+ e.g., clients can by trusted (AUTH_SYS), or required to present Kerberos user credentials (RPCSEC_GSS)
+ RPCSEC_GSS wire security can be integrity only (krb5i) or integrity and privacy (encryption, krb5p)
+ various NFS-specific security and permission rules are available
* e.g., root-squashing
- a set of RGW/S3 security credentials (unknown to NFS) is associated with each RGW NFS mount (i.e., NFS-Ganesha EXPORT)
+ all RGW object operations performed via the NFS server will be performed by the RGW user associated with the credentials stored in the export being accessed (currently only RGW and RGW LDAP credentials are supported)
* additional RGW authentication types such as Keystone are not currently supported
Configuring an NFS-Ganesha Instance
===================================
Each NFS RGW instance is an NFS-Ganesha server instance *embeddding*
a full Ceph RGW instance.
Therefore, the RGW NFS configuration includes Ceph and Ceph Object
Gateway-specific configuration in a local ceph.conf, as well as
NFS-Ganesha-specific configuration in the NFS-Ganesha config file,
ganesha.conf.
ceph.conf
---------
Required ceph.conf configuration for RGW NFS includes:
* valid [client.radosgw.{instance-name}] section
* valid values for minimal instance configuration, in particular, an installed and correct ``keyring``
Other config variables are optional, front-end-specific and front-end
selection variables (e.g., ``rgw data`` and ``rgw frontends``) are
optional and in some cases ignored.
A small number of config variables (e.g., ``rgw_namespace_expire_secs``)
are unique to RGW NFS.
ganesha.conf
------------
A strictly minimal ganesha.conf for use with RGW NFS includes one
EXPORT block with embedded FSAL block of type RGW::
EXPORT
{
Export_ID={numeric-id};
Path = "/";
Pseudo = "/";
Access_Type = RW;
SecType = "sys";
NFS_Protocols = 4;
Transport_Protocols = TCP;
# optional, permit unsquashed access by client "root" user
#Squash = No_Root_Squash;
FSAL {
Name = RGW;
User_Id = {s3-user-id};
Access_Key_Id ="{s3-access-key}";
Secret_Access_Key = "{s3-secret}";
}
}
``Export_ID`` must have an integer value, e.g., "77"
``Path`` (for RGW) should be "/"
``Pseudo`` defines an NFSv4 pseudo root name (NFSv4 only)
``SecType = sys;`` allows clients to attach without Kerberos
authentication
``Squash = No_Root_Squash;`` enables the client root user to override
permissions (Unix convention). When root-squashing is enabled,
operations attempted by the root user are performed as if by the local
"nobody" (and "nogroup") user on the NFS-Ganesha server
The RGW FSAL additionally supports RGW-specific configuration
variables in the RGW config section::
RGW {
cluster = "{cluster name, default 'ceph'}";
name = "client.rgw.{instance-name}";
ceph_conf = "/opt/ceph-rgw/etc/ceph/ceph.conf";
init_args = "-d --debug-rgw=16";
}
``cluster`` sets a Ceph cluster name (must match the cluster being exported)
``name`` sets an RGW instance name (must match the cluster being exported)
``ceph_conf`` gives a path to a non-default ceph.conf file to use
Other useful NFS-Ganesha configuration:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Any EXPORT block which should support NFSv3 should include version 3
in the NFS_Protocols setting. Additionally, NFSv3 is the last major
version to support the UDP transport. To enable UDP, include it in the
Transport_Protocols setting. For example::
EXPORT {
...
NFS_Protocols = 3,4;
Transport_Protocols = UDP,TCP;
...
}
One important family of options pertains to interaction with the Linux
idmapping service, which is used to normalize user and group names
across systems. Details of idmapper integration are not provided here.
With Linux NFS clients, NFS-Ganesha can be configured
to accept client-supplied numeric user and group identifiers with
NFSv4, which by default stringifies these--this may be useful in small
setups and for experimentation::
NFSV4 {
Allow_Numeric_Owners = true;
Only_Numeric_Owners = true;
}
Troubleshooting
~~~~~~~~~~~~~~~
NFS-Ganesha configuration problems are usually debugged by running the
server with debugging options, controlled by the LOG config section.
NFS-Ganesha log messages are grouped into various components, logging
can be enabled separately for each component. Valid values for
component logging include::
*FATAL* critical errors only
*WARN* unusual condition
*DEBUG* mildly verbose trace output
*FULL_DEBUG* verbose trace output
Example::
LOG {
Components {
MEMLEAKS = FATAL;
FSAL = FATAL;
NFSPROTO = FATAL;
NFS_V4 = FATAL;
EXPORT = FATAL;
FILEHANDLE = FATAL;
DISPATCH = FATAL;
CACHE_INODE = FATAL;
CACHE_INODE_LRU = FATAL;
HASHTABLE = FATAL;
HASHTABLE_CACHE = FATAL;
DUPREQ = FATAL;
INIT = DEBUG;
MAIN = DEBUG;
IDMAPPER = FATAL;
NFS_READDIR = FATAL;
NFS_V4_LOCK = FATAL;
CONFIG = FATAL;
CLIENTID = FATAL;
SESSIONS = FATAL;
PNFS = FATAL;
RW_LOCK = FATAL;
NLM = FATAL;
RPC = FATAL;
NFS_CB = FATAL;
THREAD = FATAL;
NFS_V4_ACL = FATAL;
STATE = FATAL;
FSAL_UP = FATAL;
DBUS = FATAL;
}
# optional: redirect log output
# Facility {
# name = FILE;
# destination = "/tmp/ganesha-rgw.log";
# enable = active;
}
}
Running Multiple NFS Gateways
=============================
Each NFS-Ganesha instance acts as a full gateway endpoint, with the
limitation that currently an NFS-Ganesha instance cannot be configured
to export HTTP services. As with ordinary gateway instances, any
number of NFS-Ganesha instances can be started, exporting the same or
different resources from the cluster. This enables the clustering of
NFS-Ganesha instances. However, this does not imply high availability.
When regular gateway instances and NFS-Ganesha instances overlap the
same data resources, they will be accessible from both the standard S3
API and through the NFS-Ganesha instance as exported. You can
co-locate the NFS-Ganesha instance with a Ceph Object Gateway instance
on the same host.
RGW vs RGW NFS
==============
Exporting an NFS namespace and other RGW namespaces (e.g., S3 or Swift
via the Civetweb HTTP front-end) from the same program instance is
currently not supported.
When adding objects and buckets outside of NFS, those objects will
appear in the NFS namespace in the time set by
``rgw_nfs_namespace_expire_secs``, which defaults to 300 seconds (5 minutes).
Override the default value for ``rgw_nfs_namespace_expire_secs`` in the
Ceph configuration file to change the refresh rate.
If exporting Swift containers that do not conform to valid S3 bucket
naming requirements, set ``rgw_relaxed_s3_bucket_names`` to true in the
[client.radosgw] section of the Ceph configuration file. For example,
if a Swift container name contains underscores, it is not a valid S3
bucket name and will be rejected unless ``rgw_relaxed_s3_bucket_names``
is set to true.
Configuring NFSv4 clients
=========================
To access the namespace, mount the configured NFS-Ganesha export(s)
into desired locations in the local POSIX namespace. As noted, this
implementation has a few unique restrictions:
- NFS 4.1 and higher protocol flavors are preferred
+ NFSv4 OPEN and CLOSE operations are used to track upload transactions
- To upload data successfully, clients must preserve write ordering
+ on Linux and many Unix NFS clients, use the -osync mount option
Conventions for mounting NFS resources are platform-specific. The
following conventions work on Linux and some Unix platforms:
From the command line::
mount -t nfs -o nfsvers=4,noauto,soft,proto=tcp <ganesha-host-name>:/ <mount-point>
In /etc/fstab::
<ganesha-host-name>:/ <mount-point> nfs noauto,soft,nfsvers=4.1,sync,proto=tcp 0 0
Specify the NFS-Ganesha host name and the path to the mount point on
the client.
Configuring NFSv3 Clients
=========================
Linux clients can be configured to mount with NFSv3 by supplying
``nfsvers=3`` and ``noacl`` as mount options. To use UDP as the
transport, add ``proto=udp`` to the mount options. However, TCP is the
preferred transport::
<ganesha-host-name>:/ <mount-point> nfs noauto,noacl,soft,nfsvers=3,sync,proto=tcp 0 0
Configure the NFS Ganesha EXPORT block Protocols setting with version
3 and the Transports setting with UDP if the mount will use version 3 with UDP.
NFSv3 Semantics
---------------
Since NFSv3 does not communicate client OPEN and CLOSE operations to
file servers, RGW NFS cannot use these operations to mark the
beginning and ending of file upload transactions. Instead, RGW NFS
starts a new upload when the first write is sent to a file at offset
0, and finalizes the upload when no new writes to the file have been
seen for a period of time, by default, 10 seconds. To change this
timeout, set an alternate value for ``rgw_nfs_write_completion_interval_s``
in the RGW section(s) of the Ceph configuration file.

=====
Pools
=====
The Ceph Object Gateway uses several pools for its various storage needs,
which are listed in the Zone object (see ``radosgw-admin zone get``). A
single zone named ``default`` is created automatically with pool names
starting with ``default.rgw.``, but a `Multisite Configuration`_ will have
multiple zones.
Tuning
======
When ``radosgw`` first tries to operate on a zone pool that does not
exist, it will create that pool with the default values from
``osd pool default pg num`` and ``osd pool default pgp num``. These defaults
are sufficient for some pools, but others (especially those listed in
``placement_pools`` for the bucket index and data) will require additional
tuning. We recommend using the `Ceph Placement Group’s per Pool
Calculator <http://ceph.com/pgcalc/>`__ to calculate a suitable number of
placement groups for these pools. See
`Pools <http://docs.ceph.com/docs/master/rados/operations/pools/#pools>`__
for details on pool creation.
Pool Namespaces
===============
.. versionadded:: Luminous
Pool names particular to a zone follow the naming convention
``{zone-name}.pool-name``. For example, a zone named ``us-east`` will
have the following pools:
- ``.rgw.root``
- ``us-east.rgw.control``
- ``us-east.rgw.meta``
- ``us-east.rgw.log``
- ``us-east.rgw.buckets.index``
- ``us-east.rgw.buckets.data``
The zone definitions list several more pools than that, but many of those
are consolidated through the use of rados namespaces. For example, all of
the following pool entries use namespaces of the ``us-east.rgw.meta`` pool::
"user_keys_pool": "us-east.rgw.meta:users.keys",
"user_email_pool": "us-east.rgw.meta:users.email",
"user_swift_pool": "us-east.rgw.meta:users.swift",
"user_uid_pool": "us-east.rgw.meta:users.uid",

Release Notes
===============
v12.1.0 Luminous (RC)
====================
This is the first release candidate for Luminous, the next long term stable release.
Major Changes from Kraken
-------------------------
* When assigning a network to the public network and not to
the cluster network the network specification of the public
network will be used for the cluster network as well.
In older versions this would lead to cluster services
being bound to 0.0.0.0:<port>, thus making the
cluster service even more publicly available than the
public services. When only specifying a cluster network it
will still result in the public services binding to 0.0.0.0.
* In previous versions, if a client sent an op to the wrong OSD, the OSD
would reply with ENXIO. The rationale here is that the client or OSD is
clearly buggy and we want to surface the error as clearly as possible.
We now only send the ENXIO reply if the osd_enxio_on_misdirected_op option
is enabled (it's off by default). This means that a VM using librbd that
previously would have gotten an EIO and gone read-only will now see a
blocked/hung IO instead.
* The "journaler allow split entries" config setting has been removed.
- *librados*:
* Some variants of the omap_get_keys and omap_get_vals librados
functions have been deprecated in favor of omap_get_vals2 and
omap_get_keys2. The new methods include an output argument
indicating whether there are additional keys left to fetch.
Previously this had to be inferred from the requested key count vs
the number of keys returned, but this breaks with new OSD-side
limits on the number of keys or bytes that can be returned by a
single omap request. These limits were introduced by kraken but
are effectively disabled by default (by setting a very large limit
of 1 GB) because users of the newly deprecated interface cannot
tell whether they should fetch more keys or not. In the case of
the standalone calls in the C++ interface
(IoCtx::get_omap_{keys,vals}), librados has been updated to loop on
the client side to provide a correct result via multiple calls to
the OSD. In the case of the methods used for building
multi-operation transactions, however, client-side looping is not
practical, and the methods have been deprecated. Note that use of
either the IoCtx methods on older librados versions or the
deprecated methods on any version of librados will lead to
incomplete results if/when the new OSD limits are enabled.
* The original librados rados_objects_list_open (C) and objects_begin
(C++) object listing API, deprecated in Hammer, has finally been
removed. Users of this interface must update their software to use
either the rados_nobjects_list_open (C) and nobjects_begin (C++) API or
the new rados_object_list_begin (C) and object_list_begin (C++) API
before updating the client-side librados library to Luminous.
Object enumeration (via any API) with the latest librados version
and pre-Hammer OSDs is no longer supported. Note that no in-tree
Ceph services rely on object enumeration via the deprecated APIs, so
only external librados users might be affected.
The newest (and recommended) rados_object_list_begin (C) and
object_list_begin (C++) API is only usable on clusters with the
SORTBITWISE flag enabled (Jewel and later). (Note that this flag is
required to be set before upgrading beyond Jewel.)
- *CephFS*:
* When configuring ceph-fuse mounts in /etc/fstab, a new syntax is
available that uses "ceph.<arg>=<val>" in the options column, instead
of putting configuration in the device column. The old style syntax
still works. See the documentation page "Mount CephFS in your
file systems table" for details.
* CephFS clients without the 'p' flag in their authentication capability
string will no longer be able to set quotas or any layout fields. This
flag previously only restricted modification of the pool and namespace
fields in layouts.
* CephFS directory fragmentation (large directory support) is enabled
by default on new filesystems. To enable it on existing filesystems
use "ceph fs set <fs_name> allow_dirfrags".
* CephFS will generate a health warning if you have fewer standby daemons
than it thinks you wanted. By default this will be 1 if you ever had
a standby, and 0 if you did not. You can customize this using
``ceph fs set <fs> standby_count_wanted <number>``. Setting it
to zero will effectively disable the health check.
* The "ceph mds tell ..." command has been removed. It is superceded
by "ceph tell mds.<id> ..."
- *MGR*
* ceph-mgr supports a default dashboard
* ceph-mgr introduces a new pecan based rest API
- *RGW*:
* RGW introduces server side encryption of uploaded objects with 3 options for
the management of encryption keys, automatic encryption (only recommended for
test setups), customer provided keys similar to Amazon SSE-C specification and
using a key management service (Openstack Barbician) similar to Amazon SSE-KMS
specification.
* RGW's metadata search with ElasticSearch now supports end user requests
serviced via RGW itself and now supports custom metadata fields
* RGW has consolidated the several metadata index pools via the use of rados
namespaces
* RGW now supports dynamic bucket index sharding

v12.0.2 Luminous (dev)
======================
This is the third development checkpoint release of Luminous, the next long term
@ -10,40 +827,6 @@ stable release.
Major changes from v12.0.1
--------------------------
* The original librados rados_objects_list_open (C) and objects_begin
(C++) object listing API, deprecated in Hammer, has finally been
removed. Users of this interface must update their software to use
either the rados_nobjects_list_open (C) and nobjects_begin (C++) API or
the new rados_object_list_begin (C) and object_list_begin (C++) API
before updating the client-side librados library to Luminous.
Object enumeration (via any API) with the latest librados version
and pre-Hammer OSDs is no longer supported. Note that no in-tree
Ceph services rely on object enumeration via the deprecated APIs, so
only external librados users might be affected.
The newest (and recommended) rados_object_list_begin (C) and
object_list_begin (C++) API is only usable on clusters with the
SORTBITWISE flag enabled (Jewel and later). (Note that this flag is
required to be set before upgrading beyond Jewel.)
* CephFS clients without the 'p' flag in their authentication capability
string will no longer be able to set quotas or any layout fields. This
flag previously only restricted modification of the pool and namespace
fields in layouts.
* CephFS directory fragmentation (large directory support) is enabled
by default on new filesystems. To enable it on existing filesystems
use "ceph fs set <fs_name> allow_dirfrags".
* CephFS will generate a health warning if you have fewer standby daemons
than it thinks you wanted. By default this will be 1 if you ever had
a standby, and 0 if you did not. You can customize this using
``ceph fs set <fs> standby_count_wanted <number>``. Setting it
to zero will effectively disable the health check.
* The "ceph mds tell ..." command has been removed. It is superceded
by "ceph tell mds.<id> ..."
* RGW introduces server side encryption of uploaded objects with 3 options for
the management of encryption keys, automatic encryption (only recommended for
test setups), customer provided keys similar to Amazon SSE KMS specification &
using a key management service (openstack barbician)

long term release. We're off to a good start to release Luminous in the spring
of '17.
Major changes from Kraken
-------------------------
* When assigning a network to the public network and not to
the cluster network the network specification of the public
network will be used for the cluster network as well.
In older versions this would lead to cluster services
being bound to 0.0.0.0:<port>, thus making the
cluster service even more publicly available than the
public services. When only specifying a cluster network it
will still result in the public services binding to 0.0.0.0.
* Some variants of the omap_get_keys and omap_get_vals librados
functions have been deprecated in favor of omap_get_vals2 and
omap_get_keys2. The new methods include an output argument
indicating whether there are additional keys left to fetch.
Previously this had to be inferred from the requested key count vs
the number of keys returned, but this breaks with new OSD-side
limits on the number of keys or bytes that can be returned by a
single omap request. These limits were introduced by kraken but
are effectively disabled by default (by setting a very large limit
of 1 GB) because users of the newly deprecated interface cannot
tell whether they should fetch more keys or not. In the case of
the standalone calls in the C++ interface
(IoCtx::get_omap_{keys,vals}), librados has been updated to loop on
the client side to provide a correct result via multiple calls to
the OSD. In the case of the methods used for building
multi-operation transactions, however, client-side looping is not
practical, and the methods have been deprecated. Note that use of
either the IoCtx methods on older librados versions or the
deprecated methods on any version of librados will lead to
incomplete results if/when the new OSD limits are enabled.
* In previous versions, if a client sent an op to the wrong OSD, the OSD
would reply with ENXIO. The rationale here is that the client or OSD is
clearly buggy and we want to surface the error as clearly as possible.
We now only send the ENXIO reply if the osd_enxio_on_misdirected_op option
is enabled (it's off by default). This means that a VM using librbd that
previously would have gotten an EIO and gone read-only will now see a
blocked/hung IO instead.
* When configuring ceph-fuse mounts in /etc/fstab, a new syntax is
available that uses "ceph.<arg>=<val>" in the options column, instead
of putting configuration in the device column. The old style syntax
still works. See the documentation page "Mount CephFS in your
file systems table" for details.
Notable Changes
@ -1475,7 +2213,7 @@ Upgrading from Jewel
to Kraken 11.2.z (or, eventually, Luminous 12.2.z).
* The ``sortbitwise`` flag must be set on the Jewel cluster before upgrading
to Kraken. The latest Jewel (10.2.4+) releases issue a health warning if
to Kraken. The latest Jewel (10.2.8+) releases issue a health warning if
the flag is not set, so this is probably already set. If it is not, Kraken
OSDs will refuse to start and will print and error message in their log.
