Hi,
I'm doing some research on Xen-Clusters with Pacemaker and OCFS2.
My playground is just a Mac book with Virtualbox and two Debian/unstable
virtual machines.
I followed this guide here:
http://publications.jbfavre.org/virtualisation/cluster-xen-corosync-pacemaker-drbd-ocfs2.en
After some OCFS2 problems, I changed my setup to use Pacemaker OCFS2
integration.
The Xen cluster comes up and works.

No stonith is configured. I have found some messages about issues with OCFS2
and no fencing:

Is there no way to handle a power outage of xen01 (virtual box poweroff
button), when stonith is disabled?
Actually xvm-01 resource can not be started on xen02, because /cluster is not
accessible on xen02.
(ls -la /cluster is hanging endlessly, it works when I power on xen01 again)
thanks for any advice in advance
Waldemar
p.s.:
cib.xml on xen02 after xen01 is killed:
