Hi Sam, As part of the effort to solve problems similar to issue #13104 (http://tracker.ceph.com/issues/13104), do you think it is appropriate to add some parameters to pool setting: 1. recovery priority of the pool - we have a customized pool recovery priority (like process's nice value) to favor some pools over others. For example, the bucket index pool is usually much much smaller but important to recover first (e.g. might affect write latency as like issue #13104). 2. pool level recovery op priority - currently we have a low priority for recovery op (by default it is 10 while client io's priority is 63), is it possible to have a pool setting to customized the priority on pool level. The purpose is to give some flexibility in terms of favor some pools over others when doing recovery, in our case using radosgw, we would like to favor bucket index pool as that is on the write path for all requests.
