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

Wed Oct 21 17:33:24 PDT 2009

ubuntu 9.04 is shipping 2.6.28. The O2NET_PROTOCOL_VERSION in that release
is the same as in ocfs2 1.4. So one should be able to concurrently mount a
volume from nodes running ubuntu 9.04 and ocfs2 1.4/centos.

Have you tried it?
