[ovirt-users] Delete disk references without deleting the disk

[Johan Kooijman]

When I deactivate the disk on a VM, I can click remove. It then offers me
the dialog te remove it with a checkbox "Remove permanently". I don't check
that, the disk will be deleted from inventory, but won't be deleted from
storage domain?
Can't try for myself, it'll kill my storage domain.
