Thanks for the response. So if I understand you correctly, you're saying
have two ocfs2/drbd's. VMs running on xenhost1 would use ocfs2/drbd/1,
and VMs running on xenhost2 would use ocfs2/drbd2. 

Like you mentioned, the concern is if someone moves one and forgets to
move it back. 

Thanks for the suggestion, adding it to the list!
