[one-users] LVM volume doesn't get deleted after VM is nuked

[Simon Boulet]

Hi Andrzej

I think your problem is related to the delete action problem that was
discussed a few weeks ago:

http://lists.opennebula.org/pipermail/users-opennebula.org/2012-December/021237.html

It is scheduled to be fixed in Release 4.0 :

http://dev.opennebula.org/issues/1685

You should try using the VM Cancel action instead of the Delete action when
possible.

Simon
