We're working on true integration right now. Jeff Mahoney has picked up
on this. However, as the work so far mostly concerns advancing OCFS2
(while heartbeat 2.0.4 should be quite powerful enough to drive it),
this is taking place on ocfs2-devel so far and not on the heartbeat

This doesn't work right now, or at least not very well.
In some time, we'll have an OCFS2 resource agent for heartbeat 2.x
(modeled as a clone), which you can then use in the heartbeat config as
a dependency etc, and which will be responsible for managing
(mounting/unmounting) the OCFS2 filesystem. This will be OCFS2 1.3.x
material, I think, and probably be relevant in time for SLES10.
Right now, well, you can start OCFS2 prior to heartbeat and put stuff on
it, and it will mostly work because the OCFS2 internal fencing and
heartbeat STONITH fencing don't step on eachother toes (much), but you
can't really model it as a dependency, they are separate entities
