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

NAME

       crmadmin - control 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.
