After a network split and recovery in a RHEL 5 or 6 cluster using fence_scsi, one node is killed and the remaining node cannot access storage devices
Issue
- In a two node cluster with
fence_scsi, if there is a a temporary network split, after recovery only one node remains in the cluster but it cannot access the storage devices - After a network issue in a two node cluster, the one remaining node is not registered to the SCSI devices any longer and gets SCSI reservation conflicts
- It seems that in a two node cluster if network connectivity is lost for a short time, the cluster ends up in an unworkable state.
Environment
- Red Hat Enterprise Linux (RHEL) 5 or 6 with the High Availability Add On
- Cluster configured to use
fence_scsi - Two-node cluster
