The problem was really one server which shouldn’t have been in the cluster at all.

<div>That means you have mismatching ocfs2.conf file. And I suspect
the node where this is failing is the one that has the bad
ocfs2.conf file. Compare the config files from all the nodes and
ensure it is the same. Or you could simply replace the one on the
failing node from another node. The file should be the same
everywhere. Remember to restart the cluster on that node.</div>
