[ovirt-users] Disk's locked of VM

Thu Jul 10 11:14:53 UTC 2014

Hello Vered,

Okay. That I understand. That was also what we where using but somehow
while activating the stateless state of that vm the disks got locked and
stayed that way even after a reboot. I suspect they activated the stateless
state and restarted that vm to soon.

Kind regards.
