A few more questions-- again maybe obvious. If a pool defines a num of copies as 6, does that mean each PG will have 6 and only 6 OSDs? How is the primary OSD determined per PG? When an OSD within a PG fails, presumably the PG would be operating outside of the target diversity/redundancy of the pool. Does that PG start to search for another OSD that can be brought into the PG to satisfy the pool diversity/ redundancy requirements? Is there a way to tell when a PG is in this hazard state?
