True, it should normally stay running, and that's actually the problem here and you just seem to be confusing consequence with consequence: - first: the corosync membership got broken on siteb-1 node (hard to tell why, the only thing we can observe is that sbd monitoring was moved there from sitea-1) - then: dlm_controld on sitea-1, which already observed that membership issue of siteb-1, proceed to ask pacemaker to fence siteb-1, which was cheerfully executed by sitea-2 node I cannot really tell what the root cause was here, but observing PID as high as 171087, I wonder if you have recent enough libqb (0.17.2): https://bugzilla.redhat.com/show_bug.cgi?id=1114852 (and would perhaps fit: new sbd process/es with high enough PIDs, exercising libqb-backed IPC -> something bad happening like corosync getting stuck or crashing -> node kicked out...) -- Nazdar, Jan (Poki)
