Hi!
I just discovered a state transition for crmd when there was nothing to do:
---
Apr 19 08:31:24 h05 crmd: [13085]: info: crm_timer_popped: PEngine Recheck
Timer (I_PE_CALC) just popped (900000ms)

So some re-check timer (I_PE_CALC) got active, and crmd changed from S_IDLE to
S_POLICY_ENGINE.
That's OK, but if the policy engine does not create any actions to perform, why
then is the transition engine activated (S_POLICY_ENGINE ->
S_TRANSITION_ENGINE)?
I see no actions performed, but still the pengine dumps the cluster-state to a
file. Shouldn't the state go from S_POLICY_ENGINE to S_IDLE instead? Or does
this happen because one cluster node is offline and standby?
I tried to examine the dumped state:
---
h05:~ # crm_simulate -V -x /tmp/pe
Current cluster status:
