Scenario:
I am trying to delete quite big amount of disks (15) from the disks tab.
Backend executes Run multiple actions and acquires lock for each object.
If,for some reason,action fails at CanDoAction (in this case CanDoAction of action RemoveDisk failed) the objects stays locked forever. As a result I have several disks that can not be deleted.
The message in UI says:Error: Can't remove Virtual Machine disk. Same action in progress.
Here is the engine.log:
