How to delete unmanaged disks in local storage
In "Storages => Local storage => Disks => Unmanaged disks" I have a handful of disks that seem to be old, however I can't seem to delete them. Is there a way to delete these? They seem to be using up disk space.
Those are likely "base copy". If it's the case, it's normal because they are "parents" of a VDI chain (snapshot, active disks etc.)
What you can probably safely remove are orphaned disks.
