Comment 3 Aharon Canan 2013-08-01 13:17:35 UTC 
verified (although 'truesize' still appears - see vdsm.log below) using sf19
Volume 1f761569-4135-439d-9fb8-0f7f7b19181a is corrupted or missing

verification steps - 
====================
1. create DC based on NFS
2. create VM without starting it.

On the NFS foler -  
  3. mv <voluuid> <voluuid>.bak
  4. mv <voluuid>.meta <voluuid>.meta.bak
  5. mv <voluuid>.lease <voluuid>.lease.bak

from vdsm.log
