Cluster service does not relocate when network cable is pulled and NFS share is mounted on cluster nodes on Red Hat Enterprise 6

Environment

• Red Hat Enterprise Linux Server 6 (with the High Availability Add on)
• Red Hat High Availability (Cluster Suite) Cluster with 2 or more nodes

• Each cluster node acts as an NFS client (ie. It mounts NFS shares to it from another source).

  • Mount options include hard so if the NFS share is unavailable, I/O's to the device hang.
  • Automount (autofs) is configured using an autofs map that is located on an NFS mounted filesystem:

• rgmanager controlling cluster services and resources

  • At least one of the services has a filesystem resource (fs).
