since this is the second time the exact same things happens to me, I doubt it's really a storage problem

Edu, related to One Shot Prepare?

Comment 5 Eduardo Warszawski 2013-11-20 08:15:06 UTC
(In reply to Allon Mureinik from comment #4)
> Edu, related to One Shot Prepare?

From the Traceback in comment #1 is obvious that the code running does not include the oneShot prepare changes.
How can be it related?
Please use git.

Comment 6 Sergey Gotliv 2013-12-17 15:10:48 UTC
This is a duplicate of BZ#1026697. 
The workaround is to put host on maintenance and then activate it again.
