cl_status - Check status of the High-Availability Linux (Linux-HA)
subsystem
cl_status sub-command options
parameters
cl_status is used to check the status of the
High-Availability Linux subsystem.
hbstatus
Indicate if heartbeat is running on the local system.
With -v, gives more details, similar to:
version: 3.0.6 (10e3f2130ea1)
managed by: pacemaker (respawn)
ccm membership with quorum
instance 12
members 2
1 bob (born: 6)
0 alice (born: 12)
member of partition
bob active (nodetype: normal)
eth1 dead
eth0 up
alice active (nodetype: normal)
eth1 dead
eth0 up
10.43.9.55 ping (nodetype: ping)
10.43.9.55 up
Note: it is not a concern if a certain link from some node to
itself is reported "dead". For example "mcast"
directives usually don't see their own network packages.
listnodes
List the nodes in the cluster.
nodetype ping|normal
List the nodes of the given type.
Note
Ping nodes are obsolete in Pacemaker cluster, having been replaced with the
pingd resource agent.
listhblinks node
List the network interfaces used as heartbeat links.
node should be specified as listed in the
ha.cf(5) file for the
cluster.
hblinkstatus node link
Show the status of a heartbeat link.
node should
be specified as listed in the
ha.cf(5) file for the cluster.
link should be as per the output of the listhblinks subcommand.
clientstatus node client [timeout]
Show the status of heartbeat clients.
node and
client should be specified as listed in the
ha.cf(5) file for
the cluster. Timeout is in milliseconds, the default is 100ms.
rscstatus
Show the status of cluster resources. Status will be one
of: local, foreign, all or none.
Note
This option is deprecated, it is obsolete in Pacemaker clusters.
parameter -p parameter
Retrieve the value of cluster parameters. The parameters
may be one of the following: apiauth, auto_failback, baud, debug, debugfile,
deadping, deadtime, hbversion, hopfudge, initdead, keepalive, logfacility,
logfile, msgfmt, nice_failback, node, normalpoll, stonith, udpport, warntime,
watchdog.
Note
Some of these options are deprecated; see
ha.cf(5)
The following options are supported by heartbeat:
-v
Report more details. Available with hbstatus, listnodes,
and listhblinks.
-m
Make the output more human readable. The default output
should be easier for scripts to parse. Available with all commands.
-p
List only 'ping' nodes. Available with listnodes
sub-command.
Note
Ping nodes are obsolete in Pacemaker cluster, having been replaced with the
pingd resource agent.
-n
List only 'normal' nodes. Available with listnodes
sub-command.
