Backport #22270

Updated by Nathan Cutler over 6 years ago

https://github.com/ceph/ceph/pull/19230 In previous code we use USED/ USED + MAX_AVAIL, in PR https://github.com/ceph/ceph/pull/10584 
 however, the USED here is nominal amount stored by the pool, but MAX_AVAIL is RAW_AVAIL can be used by the pool.
