To get this feature, one needs both a kernel = 2.6.28 and a

As of now, there are two such stacks. Pacemaker from Novell and
the new CMAN (new is my term... unsure how RH will be marketing
it)
It is waiting for the heartbeat timeout to trigger denoting a
node death. Then it initiates recovery. With the default settings,
this takes about a minute plus. This is with the o2cb cluster stack.

your cluster... num nodes, arch, mem, etc.
The oops is due to an over zealous BUG_ON. Not really required. But it
does hint at a possible race in o2dlm.

Can you describe the mount lock?
You don't have to limit the mount to just one node. Have both

Yes, this is a known issue in OCFS2 1.4.1 and 1.4.2. That is assuming

This was discussed in the email announcing the 1.4.2 release.
Sure.

This is a feature. ;)
If you have mounted a volume on two or more nodes, the expectation
is that the private interconnect will always remain up. If you shutdown
