Last updated on AUGUST 04, 2018

Applies to:

Linux OS - Version Oracle Linux 5.3 to Oracle Linux 5.9 [Release OL5U3 to OL5U9]
Information in this document applies to any platform.

Symptoms

Note: Red Hat Cluster Service (RHCS) is supported only for Oracle Linux 5.  No support is offered for Oracle Linux 6 and beyond.

Oracle Linux 5 with cman version prior to cman-2.0.115-34.el5

After rebooting the servers in the RHCS cluster, the clustered logical volume (clvm) cannot be accessed and thus the filesystem on the logical volume cannot be mounted too.
Commands such as pvs,vgs and lvs hangs
The service status for clvmd could not be checked either, which would appear hung.

The cluster is in quorate state as seen under the output of commands : clustat and cman_tool status

And the node fencing is in working condition.
