 On Oracle Linux, Oracle VM and Oracle Private Cloud Appliance (PCA), when making use of the Oracle Clustered File System version 2 (OCFS2), it may be sometimes difficult to determine if a server which rebooted has been fenced out of the ocfs2 cluster due to not writing its heartbeat in time or if the cause is external to the o2cb cluster.
