Removing pool 'mon_allow_pool_delete config option to true before you can destroy a pool1_U (500)

Question

I'm running proxmox and I try to remove a pool which I created wrong. However it keeps giving this error:

mon_command failed - pool deletion is disabled; you must first set the mon_allow_pool_delete config option to true before you can destroy a pool1_U (500)
OK

But:

root@kvm-01:~# ceph -n mon.0 --show-config | grep mon_allow_pool_delete
mon_allow_pool_delete = true
root@kvm-01:~# ceph -n mon.1 --show-config | grep mon_allow_pool_delete
mon_allow_pool_delete = true
root@kvm-01:~# ceph -n mon.2 --show-config | grep mon_allow_pool_delete
mon_allow_pool_delete = true

root@kvm-01:~# cat /etc/ceph/ceph.conf
[global]
         auth client required = cephx
         auth cluster required = cephx
         auth service required = cephx
         cluster network = 10.0.0.0/24
         filestore xattr use omap = true
         fsid = 41fa3ff6-e751-4ebf-8a76-3f4a445823d2
         keyring = /etc/pve/priv/$cluster.$name.keyring
         osd journal size = 5120
         osd pool default min size = 1
         public network = 10.0.0.0/24
[osd]
         keyring = /var/lib/ceph/osd/ceph-$id/keyring
[mon.0]
         host = kvm-01
         mon addr = 10.0.0.1:6789
         mon allow pool delete = true

[mon.2]
         host = kvm-03
         mon addr = 10.0.0.3:6789
         mon allow pool delete = true
[mon.1]
         host = kvm-02
         mon addr = 10.0.0.2:6789
         mon allow pool delete = true

So that's my full config. Any idea why I am unable to delete my pools?

Another approach:

ceph tell mon.\* injectargs '--mon-allow-pool-delete=true'
ceph osd pool rm test-pool test-pool --yes-i-really-really-mean-it

I followed your approach, and it exactly fixed my problem! Thank you! ` -- $ ssh cloud-1 sudo ceph --version ceph version 13.2.1 (5533ecdc0fda920179d7ad84e0aa65a127b20d77) mimic ` (stable) – holibut Sep 21 '18 at 01:42

This is a better approach because when the monitor is restarted, the flag is reset. – Brian Topping Nov 10 '18 at 16:44

You can turn it back off with `ceph tell mon.\* injectargs '--mon-allow-pool-delete=false'` once you've deleted your pool. – KingBob May 08 '19 at 10:28

This command is outdated, please use `ceph config set mon mon_allow_pool_delete true` instead. – Devpool Nov 07 '19 at 13:45

You can set the config via the CLI or via the dashboard of Ceph under Cluster -> Configuration (advanced settings).

The CLI command is the following:

ceph config set mon mon_allow_pool_delete true

This is the current way of doing it. – Davor Cubranic Feb 09 '21 at 23:08

you need to do:

systemctl restart ceph-mon.target

Otherwise you can restart the server an infinite number of times and nothing happens

After editing the config you need to reboot the node. After the reboot everything went smoothly!

After added the following lines to the /etc/ceph/ceph.conf or /etc/ceph/ceph.d/ceph.conf and restart the ceph.target servivce, the issue still exists.

[mon.1]
host = kvm-02
mon addr = 10.11.110.112:6789
mon allow pool delete = true
