Feature depends on existence of libqb function qb_log_file_reopen. New function call is added into CFG service API. This function is used by corosync-cfgtool which now accepts -L parameter. Finally, logrotate "postrotate" script is calling corosync-cfgtool -L to notify corosync, instead of using copytruncate option.

|
|
.SH "NAME"
|
|
corosync-cfgtool \- An administrative tool for corosync.
|
|
.SH "SYNOPSIS"
|
|
.B corosync\-cfgtool [[\-i IP_address] [\-b] \-s] [\-R] [\-L] [\-k nodeid] [\-a nodeid] [\-h] [\-H]
|
|
.SH "DESCRIPTION"
|
|
.B corosync\-cfgtool
|
|
A tool for displaying and configuring active parameters within corosync.
|
|
.SH "OPTIONS"
|
|
.TP
|
|
.B -i
|
|
Finds only information about the specified interface IP address with -s.
|
|
.TP
|
|
.B -s
|
|
Displays the status of the current links on this node for UDP/UDPU, while extended status
|
|
for KNET. If any interfaces are faulty, 1 is returned by the binary. If all interfaces are
|
|
active 0 is returned to the shell.
|
|
After each link, the nodes on that link are displayed in order with their status,
|
|
for example there are 3 nodes with KNET transportation:
|
|
LINK ID 0:
|
|
id = 192.168.100.80
|
|
status:
|
|
node 0: link enabled: 1 link connected: 1
|
|
node 1: link enabled: 1 link connected: 1
|
|
node 2: link enabled: 1 link connected: 1
|
|
.TP
|
|
.B -b
|
|
Displays the brief status of the current links on this node (KNET only) when used
|
|
with "-s". If any interfaces are faulty, 1 is returned by the binary. If all interfaces
|
|
are active 0 is returned to the shell.
|
|
After each link, the nodes on that link are displayed in order with their status
|
|
encoded into a single digit. 1=link enabled, 2=link connected, So a 3 in
|
|
a node position indicates that the link is both enabled and connected.
|
|
The local link (which will only ever be enabled on link 0) shows as enabled but
|
|
not connected for internal reasons.
|
|
The output will be:
|
|
LINK ID 0:
|
|
id = 192.168.100.80
|
|
status = 333
|
|
.TP
|
|
.B -R
|
|
Tell all instances of corosync in this cluster to reload corosync.conf.
|
|
.TP
|
|
.B -L
|
|
Tell corosync to reopen all logging files. In contrast to other subcommands,
|
|
nothing is displayed on terminal if call is successful.
|
|
.TP
|
|
.B -k
|
|
Kill a node identified by node id.
|
|
.TP
|
|
.B -a
|
|
Display the IP address(es) of a node.
|
|
.TP
|
|
.B -h
|
|
Print basic usage.
|
|
.TP
|
|
.B -H
|
|
Shutdown corosync cleanly on this node.
