It's true that CIB will get larger if it keeps them...
I want to ask one more about this case;

(1) resource starts on DC

============

Current DC: node-b (59295d90-5459-490d-a1e0-d48810cf2fb3)

1 Resources configured.

dummy   (ocf::heartbeat:Dummy): Started node-b

Operations:
* Node node-b:
   dummy:

    + monitor: interval=10000ms rc=0 (ok)
* Node node-a:



(2) resource do a failover from DC to non-DC

    + stop: rc=0 (ok)
* Node node-a:
   dummy:
    + start: rc=0 (ok)
    + monitor: interval=10000ms rc=0 (ok)

Failed actions:
    dummy_monitor_10000 (node=node-b, call=4, rc=7): complete



(3) stop non-DC node

Full list of resources:

dummy   (ocf::heartbeat:Dummy): Stopped

Operations:
* Node node-b:
   dummy:  fail-count=1
    + start: rc=0 (ok)
    + monitor: interval=10000ms rc=7 (not running)
    + stop: rc=0 (ok)
* Node node-a:
   dummy:
    + start: rc=0 (ok)
    + monitor: interval=10000ms rc=0 (ok)
    + stop: rc=0 (ok)

Failed actions:
    dummy_monitor_10000 (node=node-b, call=4, rc=7): complete



It seems that DC can keep its failure history.
Does it mean dummy_monitor_10000 (call=4) is in the current start/stop
series?


Thanks,
