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

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.<o:p></o:p></p>
