It's not necessary to restart a mon if you just want to delete a pool,
even if the "not observed" message appears. And I would not recommend
to permanently enable the "easy" way of deleting a pool. If you are
not able to delete the pool after "ceph tell mon ..." try this:
ceph daemon mon.<YOUR_MON> config set mon_allow_pool_delete true
and then retry deleting the pool. This works for me without restarting
any services or changing config files.

I was testing IO and I created a bench pool.
But if I tried to delete I get:
Error EPERM: pool deletion is disabled; you must first set the
mon_allow_pool_delete config option to true before you can destroy a
pool
So I run:
ceph tell mon.\* injectargs '--mon-allow-pool-delete=true'
mon.ceph-node1: injectargs:mon_allow_pool_delete = 'true' (not
observed, change may require restart)
mon.ceph-node2: injectargs:mon_allow_pool_delete = 'true' (not
observed, change may require restart)
mon.ceph-node3: injectargs:mon_allow_pool_delete = 'true' (not
observed, change may require restart)
I restarted all the nodes.
But the flag has not been observed.
Is this the right way to remove a pool?
i think you need to set the option in the ceph.conf of the monitors.
and then restart the mon's one by one.
afaik that is by design.
