To speed up the deletion, you can remove the rbd_header (if the image is empty) and then remove it.
For example: $ rados -p rbd ls huge.rbd rbd_directory $ rados -p rbd rm huge.rbd $ time rbd rm huge 2013-12-10 09:35:44.168695 7f9c4a87d780 -1 librbd::ImageCtx: error finding header: (2) No such file or directory Removing image: 100% complete...done.
