NAME
cl_status - Check status of the High-Availability Linux (Linux-HA) subsystem SYNOPSIS
cl_status sub-command options parameters DESCRIPTION
cl_status is used to check the status of the High-Availability Linux subsystem. SUPPORTED SUB-COMMANDS hbstatus Indicate if heartbeat is running on the local system. 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 Note This option is deprecated, it is obsolete in Pacemaker clusters.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) OPTIONS
The following options are supported by heartbeat: -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. SEE ALSO
