The issue that should be handled here, is with task 00f09763-b45c-49f6-a143-65bae9c80485 disappears from SPM after restart.
Comment 3 Barak 2012-09-11 10:51:58 EDT
Maor - restart SPM = restart vdsm(SPM) or reboot host?
Comment 4 Maor 2012-09-12 04:01:38 EDT
The original reproduce steps were rebooting, so I guess it's better to go on the safe side and perform a reboot on the host,
Although I think restart vdsm(SPM) might also work,
The key is that when a new host is selected to be SPM, it does not see the task which was created in the previous SPM.
