Ilya Dryomov afbf90d5b5 rbd: du command should take spec as an argument ... Change du to take <image-spec> | <snap-spec> as an argument instead of going through --image option. The new synopsis is (du | disk-usage) [<image-spec> | <snap-spec>] This is to make it look more like the rest of the commands: the only other command that takes pool as an argument is ls and it can't really serve as a prototype for du, because the latter has to work on images and snapshots as well. Examples: # stats for pool rbd $ rbd du $ rbd -p rbd du # stats for pool foo $ rbd -p foo du # stats for snapshot mysnap of image baz in pool rbd $ rbd du baz@mysnap # stats for image bar in pool foo $ rbd du foo/bar Signed-off-by: Ilya Dryomov <idryomov@gmail.com>		2015-07-27 12:22:04 +03:00
