It's much more useful information than the strace you submitted earlier. :-)

Please find out _what_ that unsupported optional feature is on your ocfs2, and 
let us know the results. "PAGER=cat debugfs.ocfs2 -R stats /dev/drbd0" is 
your friend, and tunefs.ocfs2 once you know what to fix.

However, it seems you are primarily dealing with an OCFS2 issue, not a DRBD 
issue. So perhaps this list isn't the most helpful resource in 
troubleshooting your problem.
