Each pool has a finite number of reservations, but if one pool has no more slots the other may still grant reservations. > If there's more than one possible replica to backfill from could we try > to reserve others if the first is busy instead of waiting? I think you may have your backfill terminology backward. We don't backfill from a replica, we backfill to a replica. There will never be more than one replica that needs to be backfilled to. > Why would a remote backfill reservation fail if the OSD is full > (disk space)?

This change I implemented a few weeks ago and was merged last week. Backfill does write to the replica. -- To unsubscribe from this list: send the line "unsubscribe ceph-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
