Absolutely. It doesn't affect the ability to take, retain, or recover using snapshots. It only affects the ability to see how much space a particular snapshot is using on disk, both from the user wanting to know and snapper using it to make retention decisions. Snapper can handle qgroups not being there. -Jeff -- Jeff Mahoney SUSE Labs
