Hi,
I have a small 8TB testing cluster. During testing I've used 94G.
But, I have since removed pools and images from Ceph, I shouldn't be
using any space, but still the 94G usage remains. How can I reclaim old
used space?
Also, this:-
ceph@ceph-admin:~$ rbd rm 6fa36869-4afe-485a-90a3-93fba1b5d15e

rbd: image has snapshots - these must be deleted with 'rbd snap purge'
before the image can be removed.
ceph@ceph-admin:~$ rbd snap purge 6fa36869-4afe-485a-90a3-93fba1b5d15e
-p cloudstack

Lastly, how can I remove a user from the auth list?

Jon
