[Ocfs2-users] Unable to mount cluster on CentOS and Ubunut at the same time

[John McNulty]

I don't think what you want to do is possible. Oracle provide specific
builds for comercial distributions only. Centos works with those
builds because it mirrors Redhat. Ubuntu is not on Oracle's supported
list, but has OCFS2 functionality included because OCFS2 is now part
of the upstream kernel.  Redhat (and therefore Centos) don't use
vanilla upstream kernels they roll their own. So you're never - or at
least very unlikely - going to get a version match between Redhat and
Ubuntu.

Your only option I think is going to be a backup and restore.
