The 'big picture' of Ceph MDS is that it is a cluster of MDS servers that automatically balance load and handle failure. However that is really hard to do. So for the first production release of Ceph file system they use a primary-backup scheme that handles failure, but not doesn't attempt to do load balancing.

If you add another OSD (OSD 3), some PGs will now map to OSD 3 instead of one of the others. However, until OSD 3 is backfilled, the PG will have a temporary mapping allowing it to continue to serve I/O from the old mapping. During that time, the PG is misplaced, because it has a temporary mapping, but not degraded, since there are 3 copies.
