Hi Shani,
no tasks listed in UI, and now "taskcleaner.sh -o" reports no task (just
before I gave "taskcleaner.sh -r").
But disks are still locked, and "unlock_entity.sh -q -t all -c"
(accordingly) reports only two disk's uuid (with their vm's uuid).

Time to give a chance to unlock_entity.sh?

Regards,
gc
