Name

crmadmin — controls the Cluster Resource Manager

Synopsis

crmadmin [-V|-q] [-i|-d|-K|-S|-E] node
crmadmin [-V|-q] -N -B
crmadmin [-V|-q] -D
crmadmin -v
crmadmin -?

Description

crmadmin was originally designed to control most of the actions of the CRM daemon. However, the largest part of its functionality has been made obsolete by other tools, such as crm_attribute and crm_resource. Its remaining functionality is mostly related to testing and the status of the crmd process.

[Warning]

Some crmadmin options are geared towards testing and cause trouble if used incorrectly. In particular, do not use the --kill or --election options unless you know exactly what you are doing.

Options

--help, -?

Print the help text.

--version, -v

Print version details for HA, CRM, and CIB feature set.

--verbose, -V

Turn on command debug information.

[Note]

Increase the level of verbosity by providing additional instances.

--quiet, -q

Do not provide any debug information at all and reduce the output to a minimum.

--bash-export, -B

Create bash export entries of the form export uname=uuid. This applies only to the crmadmin -N node command.

[Note]

The -B functionality is rarely useful and may be removed in future versions.

Commands

--debug_inc node, -i node

Increment the CRM daemon's debug level on the specified node. This can also be achieved by sending the USR1 signal to the crmd process.

--debug_dec node, -d node

Decrement the CRM daemon's debug level on the specified node. This can also be achieved by sending the USR2 signal to the crmd process.

--kill node, -K node

Shut down the CRM daemon on the specified node.

[Warning]

Use this with extreme caution. This action should normally only be issued by Heartbeat and may have unintended side effects.

--status node, -S node

Query the status of the CRM daemon on the specified node.

The output includes a general heath indicator and the internal FSM state of the crmd process. This can be helpful when determining what the cluster is doing.

--election node, -E node

Initiate an election from the specified node.

[Warning]

Use this with extreme caution. This action is normally initiated internally and may have unintended side effects.

--dc_lookup, -D

Query the uname of the current DC.

The location of the DC is only of significance to the crmd internally and is rarely useful to administrators except when deciding on which node to examine the logs.

--nodes, -N

Query the uname of all member nodes. The results of this query may include nodes in offline mode.

[Note]

The -i, -d, -K, and -E options are rarely used and may be removed in future versions.
