Seeing 'deep cp', 'cp' and 'import/export' I thought maybe ask > first, before I destroy something. The `rbd mv` is just an alias for `rbd rename`, so it can be used just to rename an image within a pool. Which I suppose is not what you want. `rbd cp` will copy only one image snapshot (or the image head) to the destination. `rbd deep cp` will copy all image snapshots and the image head. It looks like you want `rbd deep cp` for your task but from your example I am not sure I understand what problems you have with it? The new format 'import/export' can also be used for copying all snapshots. And there is `rbd migration` [1] which among other things may be used as "deep move" between the pools. May be this is what you want?
