Hi. Thanks for the reply.

The startup order for services is currently:

  S09sshd
  S13open-iscsi
  S14o2cb
  S15ocfs2

and the shutdown order is:

  K07ocfs2
  K08o2cb
  K09open-iscsi
  K13sshd

So I think the ordering is already as you suggest.

I will try disabling the K*open-iscsi init script, but I don't think
that is the problem. I can trigger the panic manually by calling
/etc/init.d/o2cb stop (see the first transcript in my original mail).

Are you saying that ocfs2 was not usable for your situation? Can you
explain why?

Thanks.
