Comment 2 Oved Ourfali 2014-10-07 05:06:42 UTC

Omer - wasn't that fixed by Vitor?

Comment 3 Omer Frenkel 2014-10-07 15:08:43 UTC

yes, looks like duplicate of bug 1145728

can you please attach vdsm.log just to be sure?
(or try again on vt5 where it suppose to be fixed, if its the same)

Comment 4 Omer Frenkel 2014-10-21 12:20:00 UTC
