Am I correct in thinking I was talking to you about this on IRC recently?

If so, you'll want to use SUSE 10.1 which uses the same kernel as
SLES10 and therefor has the patches that allow OCFS2 to get its
membership information from heartbeat.  10.2 has a mostly unmodified
kernel.

Once you get that, you'll be able to follow the document I mentioned.
