I can see there is a problem from the system logs:

another abrt dump of crm_mon crash
The problem appeared again in normal use.
After the first crash crm_mon crashed on every other run on both nodes of the cluster reporting 'There is no cluster running onthis node' althought pacemaker was runnning.
After pacemaker restart through 'systemctl restart pacemaker' it started working again.
