I was able to delete a pool just by using the injectargs that you 
showed above.


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`.

Re: [ceph-users] Cannot delete a pool

2018-03-01 Thread David Turner 
When dealing with the admin socket you need to be an admin.  `sudu` or
`sudo -u ceph` ought to get you around that.

I was able to delete a pool just by using the injectargs that you showed
above.

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`.

Hi,

connect to the ceph-node1 machine and run : ceph daemon mon.ceph-node1 config 
set mon_allow_pool_delete true

You are just using the wrong parameter as an ID

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.

IIRC, “not observed” means the option value could not dynamically get changed 
during online. 
So you should set the option in the config file and restart monitor nodes.
