Well, that's who's got it open. Task 7354, 27005 and 27174. See which you may be able to stop or kill.

Hi James,
even stoping Xen I couldn't umount my file system and set drbdadm secondary.
This is my output:
root at cloud15:/home/cloud15# umount /mnt/drbd7/
umount: /mnt/drbd7: device is busy.
(In some cases useful info about processes that use
the device is found by lsof(8) or fuser(1))
root at cloud15:/home/cloud15# drbd-overview
7:r7 StandAlone Primary/Unknown UpToDate/DUnknown r----- /mnt/drbd7 ext3 23G 8.3G 14G 39%
Any hint?
Thanks

a separate system just for XEN. You are probably having some kernel based conflicts that is blocking the release of the volume(s).

Hi Arnold,
I will try to stop Xen.
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.
Now I am not using Corosyn+Pacemaker anymore :(
Do you have some clue to me about this?
Thanks in advance!
Felipe

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

Have fun,
