Hi Muhammad!
Could you be a little bit more elaborate on your fencing-setup!
I read about you using SBD but I don't see any sbd-fencing-resource.
For the case you wanted to use watchdog-fencing with SBD this
would require stonith-watchdog-timeout property to be set.
But watchdog-fencing relies on
@Ulrich,
issue I am facing is that when both nodes get crashed and then if I keep
one node offline, the online node doesn't start the ocfs2 resources.

Hello Gang,
as informed, previously cluster was fixed to start the ocfs2 resources by
a) crm resource start dlm
b) mount/umount the ocfs2 file system manually. (this step was the fix)
and then starting the clone group(which include dlm, ocfs2 file systems)
worked fine:
c) crm resource

Hello Gang,
to follow your instructions, I started the dlm resource via:
crm resource start dlm
then mount/unmount the ocfs2 file system manually..(which seems to be
the fix of the situation).
Now resources are getting started properly on a single node.. I am happy
as the issue is
Hello Muhammad,
Usually, ocfs2 resource startup failure is caused by mount command timeout (or
hanged).
The sample debugging method is,
remove ocfs2 resource from crm first,
then mount this file system manually, see if the mount command will be timeout
or hanged.
If this command is hanged,

I think this problem is not in ocfs2, the cause looks like the cluster quorum
