If you realy created and destroyed OSDs before the cluster healed itself, this data will be permanently lost (not found / inactive). Also your PG count is so much oversized, the calculation for peering will most likely break because this was never tested.
If this is a critical cluster, I would start a new one and bring back the backups (using a better PG count). Kevin Am Fr., 4.
