The ocfs2 version in node1 and node0 isn't the same, so they can't coexist with each other(mount the same volume simultaneously). So I would suggest you to either change the node0 from Debian to CentOS or make the same ocfs2 version in both nodes. From the message, it looks that your CentOS has ocfs2-1.2.* while your Debian is a bit newer(ocfs2 is shipped with the mainline kernel it used I guess). Currently for CentOS 5, we only have 1.2.* and 1.4.*, So I don't think you can find a suitable ocfs2 version compatible with your debian.
