I see, thanks for the reply! BTW, while the snapshots are not removed yet, should we be able to delete the image that had the snapshots being deleted? We noticed the following for the images that had snapshots deleted, but not actually removed from the system: ``` This means the image is still open or the client using it crashed. Try again after closing/unmapping it or waiting 30s for the crashed client to timeout. ``` After executing the "rbd rm", we receive that message, and the image still displays with the "rbd ls" command. However, the "rbd info" returns a message saying that the image does not exist. Is that a known issue/situation?
