It's definitely broken in 2.1.3. It doesn't have a working "monitor"
function, it has a syntax error in ip command (at least for Fedora
distro), it doesn't offline a resource when it's stopped and so on, it
even doesn't set a path to /etc/init.d/o2cb properly . If it works for
you that means that you have a modified version, not the one that
comes with 2.1.3.

Unfortunately I'm not familiar with openAIS. Does it mean that
Heartbeat won't support OCFS2? I mean combination of CRM + openAIS
will work with OCFS2 but CRM + Heartbeat won't.
