Hi Arnold,
<div><br>
</div>
<div>I will try to stop Xen.</div>
<div><br>
</div>
<div>Talking about stonith/fencing I was working with Corosync+Pacemaker+Xen+DRBD but the pace maker configurations got failed when I put all components together. I mean, when I was with Corosync+Pacemaker+DRBD the fencing worked well! After I put Xen together
the pacemaker configuration got failed.</div>
<div><br>
</div>
<div>Now I am not using Corosyn+Pacemaker anymore :(</div>
<div><br>
</div>
<div>Do you have some clue to me about this?</div>
<div><br>
</div>
<div>Thanks in advance!</div>
<div>Felipe<br>

Well, then make xen stop when you have to switch-over the primary. Or<br>
at least make xen stop using that directory. Could be its still running<br>
vms from there, could be its only still looking at the dir because it<br>
'could' run vms from there.<br>
If you or your cluster-manager want to fail-over the resource and that<br>
fails, its a case for stonith/fencing. Or a case for a manual reboot if<br>
you haven't configured fencing yet.<br>
