Chapter 22. Delete a Pool
To delete a pool, execute:
ceph osd pool delete <pool-name> [<pool-name> --yes-i-really-really-mean-it]
If you created your own rulesets and rules for a pool you created, you should consider removing them when you no longer need your pool. If you created users with permissions strictly for a pool that no longer exists, you should consider deleting those users too.
