Very large omaps can take quite a while.
You meta data PGs *are* backfilling. It is the "61 keys/s" statement in the ceph status output in the recovery I/O line. If this is too slow, increase osd_max_backfills and osd_recovery_max_active.
Or just have some coffee ...
I already had increased osd_max_backfills and osd_recovery_max_active in order to speed things up, and most of the PGs were remapped pretty quick (couple of minutes), but these last 3 PGs took almost two hours to complete, which was unexpected.
