https://docs.ceph.com/en/reef/rbd/rbd-snapshot/ should give you everything you
need.
Sounds like maybe you have snapshots / clones that have left the parent
lingering as a tombstone?
Start with
rbd children volume-ssd/volume-8a30615b-1c91-4e44-8482-3c7d15026c28
rbd info volume-ssd/volume-8a30615b-1c91-4e44-8482-3c7d15026c28
rbd du volume-ssd/volume-8a30615b-1c91-4e44-8482-3c7d15026c28
That looks like the only volume in that pool? If targeted cleanup doesn’t
work, you could just delete the whole pool, but triple check everything before
taking action here.
