OCFS2 Cluster.conf
The OCFS2 Cluster.conf will be automatically generated by the initrd from /etc/cluster/cluster.conf. To validate use com-queryclusterconf convert ocfs2 and you'll see the output. It should be somehow like as follows.
If so redirect the output to /etc/ocfs2/cluster.conf in order to setup the filesystem.
