id

Unique name for the action. The system assigns this when you configure an operation.

name

The action to perform. Common values: monitor, start, stop

interval

If set to a nonzero value, a recurring operation is created that repeats at this frequency, in seconds. A nonzero value makes sense only when the action name is set to monitor. A recurring monitor action will be executed immediately after a resource start completes, and subsequent monitor actions are scheduled starting at the time the previous monitor action completed. For example, if a monitor action with interval=20s is executed at 01:00:00, the next monitor action does not occur at 01:00:20, but at 20 seconds after the first monitor action completes.

If set to zero, which is the default value, this parameter allows you to provide values to be used for operations created by the cluster. For example, if the interval is set to zero, the name of the operation is set to start, and the timeout value is set to 40, then Pacemaker will use a timeout of 40 seconds when starting this resource. A monitor operation with a zero interval allows you to set the timeout/on-fail/enabled values for the probes that Pacemaker does at startup to get the current status of all resources when the defaults are not desirable.

timeout

If the operation does not complete in the amount of time set by this parameter, stop the operation and consider it failed. The default value is the value of timeout if set with the pcs resource op defaults command, or 20 seconds if it is not set. If you find that your system includes a resource that requires more time than the system allows to perform an operation (such as start, stop, or monitor), investigate the cause and if the lengthy execution time is expected you can increase this value.

The timeout value is not a delay of any kind, nor does the cluster wait the entire timeout period if the operation returns before the timeout period has completed.

on-fail

The action to take if this action ever fails. Allowed values:

* ignore - Pretend the resource did not fail

* block - Do not perform any further operations on the resource

* stop - Stop the resource and do not start it elsewhere

* restart - Stop the resource and start it again (possibly on a different node)

* fence - STONITH the node on which the resource failed

* standby - Move all resources away from the node on which the resource failed

* demote - When a promote action fails for the resource, the resource will be demoted but will not be fully stopped. When a monitor action fails for a resource, if interval is set to a nonzero value and role is set to Promoted the resource will be demoted but will not be fully stopped.

The default for the stop operation is fence when STONITH is enabled and block otherwise. All other operations default to restart.

enabled

If false, the operation is treated as if it does not exist. Allowed values: true, false
