Resource group doesn't relocate when storage is disconnected and 0 paths remain active in pacemaker cluster
Issue
When unplugging storage used for cluster resource (Fibre Channel cables from the server) the multipath correctly reports 0 remaining paths however the FS and LVM resources are still reported as Started by pacemaker. It seems that pacemaker doesn't spot the failure.
The pacemaker has FS resource on top of LVM resource which sits on the device from which is being unplugged.
Multipath reports following messages:
