Issue

What actions are necessary to bring a cluster node running GFS2 back into the cluster?
Why did I have to power cycle both systems in order to recover the cluster?

Red Hat Enterprise Linux Server (RHEL) including
- Red Hat Enterprise Linux Server 5 (with the High Availability and Resilient Storage Add Ons)
- Red Hat Enterprise Linux Server 6 (with the High Availability and Resilient Storage Add Ons)
2 or more Red Hat Cluster Suite nodes in a cluster
GFS2 filesystem mounted on the particular node that is hung
Storage Fencing is used (eg. fence_scsi, fence_brocade, etc)
