[ClusterLabs] single node fails to start the ocfs2 resource

Hello Muhammad,
I think this problem is not in ocfs2, the cause looks like the cluster quorum is missed.
For two-node cluster (does not three-node cluster), if one node is offline, the quorum will be missed by default.
So, you should configure two-node related quorum setting according to the pacemaker manual.
Then, DLM can work normal, and ocfs2 resource can start up.
Thanks
Gang
