[Pacemaker] OCF Resource agent monitor activity failed due to temporary error

[Kulovits Christian - OS ITSC]

Hi Andreas,
Exactly this is what i want pacemaker to do when my RA is not able to determine the resource´s state. But without running into timeout and restart.
It's the method to display the resource´s state that is unavailable not the resource itself. This typically approach must be coded in every RA instead of once in pacemaker.

But in this situation he would say "don't know". When I set "on-fail=ignore" this error will be ignored the same way as when response is "not running" and the resource will never be restarted.

A typically approach is to wait a little bit and retry the monitor
command until it succeeds to deliver a valid status (running/not
running) or the RA monitor operation timeouts and the script is killed
including resource recovery.

Andreas
