[ClusterLabs] cluster stops randomly

[‪H Yavari‬ ‪]

Hi,
I have a cluster and it works good, but I see sometimes cluster is stopped on all nodes and I should start manually. pcsd service is running but cluster is stopped.I see the pacemaker log but I couldn't find any warning or error. what is the issue? 
(stonith is disable.)

Regards,H.Yavari
