|
|
.Nm zpool

.
|
|
.Sh DESCRIPTION
|
|
Adds the specified virtual devices to the given pool.
|
|
The
|
|
.Ar vdev
|
|
specification is described in the
|
|
.Em Virtual Devices
|
|
section of
|
|
.Xr zpoolconcepts 7 .
|
|
The behavior of the
|
|
.Fl f
|
|
option, and the device checks performed are described in the
|
|
.Nm zpool Cm create
|
|
subcommand.
|
|
.Bl -tag -width Ds
|
|
.It Fl f
|
|
Forces use of
|
|
.Ar vdev Ns s ,
|
|
even if they appear in use or specify a conflicting replication level.
|
|
Not all devices can be overridden in this manner.
|
|
.It Fl g
|
|
Display
|
|
.Ar vdev ,
|
|
GUIDs instead of the normal device names.
|
|
These GUIDs can be used in place of
|
|
device names for the zpool detach/offline/remove/replace commands.
|
|
.It Fl L
|
|
Display real paths for
|
|
.Ar vdev Ns s
|
|
resolving all symbolic links.
|
|
This can be used to look up the current block
|
|
device name regardless of the
|
|
.Pa /dev/disk
|
|
path used to open it.
|
|
.It Fl n
|
|
Displays the configuration that would be used without actually adding the
|
|
.Ar vdev Ns s .
|
|
The actual pool creation can still fail due to insufficient privileges or
|
|
device sharing.
|
|
.It Fl P
|
|
Display real paths for
|
|
.Ar vdev Ns s
|
|
instead of only the last component of the path.
|
|
This can be used in conjunction with the
|
|
.Fl L
|
|
flag.
|
|
.It Fl o Ar property Ns = Ns Ar value
|
|
Sets the given pool properties.
|
|
See the
|
|
.Xr zpoolprops 7
|
|
manual page for a list of valid properties that can be set.
|
|
The only property supported at the moment is
|
|
.Sy ashift .
|
|
.El
|
|
.
|
|
.Sh EXAMPLES
|
|
.\" These are, respectively, examples 5, 13 from zpool.8
|
|
.\" Make sure to update them bidirectionally
|
|
.Ss Example 1 : No Adding a Mirror to a ZFS Storage Pool
|
|
The following command adds two mirrored disks to the pool
|
|
.Ar tank ,
|
|
assuming the pool is already made up of two-way mirrors.
|
|
The additional space is immediately available to any datasets within the pool.
|
|
.Dl # Nm zpool Cm add Ar tank Sy mirror Pa sda sdb
|
|
.
|
|
.Ss Example 2 : No Adding Cache Devices to a ZFS Pool
|
|
The following command adds two disks for use as cache devices to a ZFS storage
|
|
pool:
|
|
.Dl # Nm zpool Cm add Ar pool Sy cache Pa sdc sdd
|
|
.Pp
|
|
Once added, the cache devices gradually fill with content from main memory.
|
|
Depending on the size of your cache devices, it could take over an hour for
|
|
them to fill.
|
|
Capacity and reads can be monitored using the
|
|
.Cm iostat
|
|
subcommand as follows:
|
|
.Dl # Nm zpool Cm iostat Fl v Ar pool 5
