crm_standby

CRM_STANDBY(8)							  [FIXME: manual]						    CRM_STANDBY(8)

NAME

       crm_standby - manipulate a node's standby attribute to determine whether resources can be run on this node

SYNOPSIS

	   crm_standby [-?|-V] -D -u|-U node -r resource

	   crm_standby	[-?|-V] -G -u|-U node -r resource

	   crm_standby [-?|-V] -v string -u|-U node -r resource [-l string]

DESCRIPTION

       The crm_standby command manipulates a node's standby attribute. Any node in standby mode is no longer eligible to host resources and any
       resources that are there must be moved. Standby mode can be useful for performing maintenance tasks, such as kernel updates. Remove the
       standby attribute from the node when it should become a fully active member of the cluster again.

       By assigning a lifetime to the standby attribute, determine whether the standby setting should survive a reboot of the node (set lifetime
       to forever) or should be reset with reboot (set lifetime to reboot). Alternatively, remove the standby attribute and bring the node back
       from standby manually.

OPTIONS

       --help, -?
	   Print a help message.

       --verbose, -V
	   Turn on debug information.

	       Note
	       Increase the level of verbosity by providing additional instances.

       --quiet, -Q
	   When doing an attribute query using -G, print just the value to stdout. Use this option with -G.

       --get-value, -G
	   Retrieve rather than set the preference.

       --delete-attr, -D
	   Specify the attribute to delete.

       --attr-value string, -v string
	   Specify the value to use. This option is ignored when used with -G.

       --node-uuid node_uuid, -u node_uuid
	   Specify the UUID of the node to change.

       --node-uname node_uname, -U node_uname
	   Specify the uname of the node to change.

       --lifetime string, -l string
	   Determine how long this preference lasts. Possible values are reboot or forever.

	       Note
	       If a forever value exists, it is always used by the CRM instead of any reboot value.

EXAMPLES

       Have a local node go to standby:

	       crm_standby -v true

       Have a node (node1) go to standby:

	       crm_standby -v true -U node1

       Query the standby status of a node:

	       crm_standby -G -U node1

       Remove the standby property from a node:

	       crm_standby -D -U node1

       Have a node go to standby for an indefinite period of time:

	       crm_standby -v true -l forever -U node1

       Have a node go to standby until the next reboot of this node:

	       crm_standby -v true -l reboot -U node1

FILES

       /var/lib/heartbeat/crm/cib.xml--the CIB (minus status section) on disk. Editing this file directly is strongly discouraged.
