[ClusterLabs] 5 minute repeat warnings

[BASDEN, ALASTAIR G.]

Hi,

In our /var/log/messages, we are getting messages repeated every 5 
minutes:
Nov 26 08:22:02 c6mds1 crmd[26950]:  notice: State transition S_IDLE -> 
S_POLICY_ENGINE
Nov 26 08:22:02 c6mds1 pengine[26949]:  notice: On loss of CCM Quorum: 
Ignore
Nov 26 08:22:02 c6mds1 pengine[26949]:  notice: Calculated transition 
1397, saving inputs in /var/lib/pacemaker/pengine/pe-input-184.bz2
Nov 26 08:22:02 c6mds1 crmd[26950]:  notice: Transition 1397 (Complete=0, 
Pending=0, Fired=0, Skipped=0, Incomplete=0, 
Source=/var/lib/pacemaker/pengine/pe-input-184.bz2): Complete
Nov 26 08:22:02 c6mds1 crmd[26950]:  notice: State transition 
S_TRANSITION_ENGINE -> S_IDLE


Can anyone advise what this is about and how to stop the messages?  pcs 
resource cleanup doesn't help.

We're on centos7.6.

Thanks,
Alastair.
