and of heartbeat? This is a _heartbeat_ mailing list remember...

The concept being that its a bad idea to have OCFS2 and Heartbeat
_not_ share the same membership information (essentially you have two
clusters).  With these patches ocfs2 goes into a sort of slave-mode
and takes orders from Heartbeat.

generally speaking, thats a terrible idea (for the same reason that
the membership information will differ and non-cluster nodes will be
running cluster resources).

See my comment in the previous email regarding non-cluster nodes
running cluster resources.

Given how little you seem to be using heartbeat, perhaps the drbd or
ocfs2 lists might be a more appropriate forum.
