When dealing with the admin socket you need to be an admin. `sudu` or `sudo -u ceph` ought to get you around that.
ceph tell mon.\* injectargs '--mon-allow-pool-delete=true'
ceph osd pool rm pool_name pool_name --yes-i-really-really-mean-it
ceph tell mon.\* injectargs '--mon-allow-pool-delete=false'
If you see the warning 'not observed, change may require restart' you can check to see if it took effect or not by asking the daemon what it's setting is `ceph daemon mon.ceph_node1 config get mon_allow_pool_delete`.
