This reminds me of a problem you might hit with this:

RBD clones track the parent image pool by id, so they'll continue
working after the pool is renamed. If you have any clones of the
images-old pool, they'll stop working when that pool is deleted.

To get around this, you'll need to flatten any clones whose parents are
in images-old before deleting the images-old pool.
