[Pacemaker] xen-cluster with ocfs2

[Waldemar Brodkorb]

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
