Description of problem:
When trying to remove a DC, after maintenance the storage domain attached to it , no error message displayed but in the events log (web portal) there is a tuple that syas "Failed to remove Data Center". The situation is that you can not:
remove the DC, activate the attached domain.
also, the DC's status is : non responsive.
from the vdsm.log:

From the log it seems that DeactivateStorageDomain was called several time.
DeactivateStorageDomain increases the master version and later send it to VDSM.
Recently there was a fix in that area of code introduced in commit 87902a0a08a4ceffcb0bdb9d45ec4a01f8b86a7e which I believe might fix this issue, but since this bug does not reproduce consistently and there are no reproduce steps, I can't be sure.
Liron, what do you think? Is your patch might fix that?
Aharon, reproduction steps?
No actual steps were taken that cause this bug.
also tried to debug this issue to figure out what cause the problem but i didn't see anything unusual
