Description of problem: I created a new volume from the Engine, and selected "optimize for virt.store" Volume is created, I hit start. Volume starts. Button "Optimize for virtstore" still shows on volume that was already optimized. Expected behaviour: Engine should be able to tell if a volume has already been optimized, and adjust which buttons to show the user. Like, when I click "Start", I can't click "Start" again.
Currently, there's no foolproof way to know if a volume has already been optimized. If the user has set the volume option from UI, then we can identify it. But if options are set manually from UI, engine does not know of it and cannot mark it.
