Thanks, Gilles. I recently opened a PR to improve RBD image listing ( https://github.com/ceph/ceph/pull/39344). In your specific case, I think that part of the issue could come from calculating the actually provisioned capacity.
Could you please share the image details (or an `rbd info <img>` dump), like this?
