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.
consider removing them when you no longer need your pool::

ceph osd pool get {pool-name} crush_ruleset

If the ruleset was "123", for example, you can check the other pools like so::

ceph osd dump | grep "^pool" | grep "crush_ruleset 123"

If no other pools use that custom ruleset, then it's safe to delete that
ruleset from the cluster.

If you created users with permissions strictly for a pool that no longer
exists, you should consider deleting those users too::

ceph auth list | grep -C 5 {pool-name}
ceph auth del {user}
