Betreff: Re: pgs incomplete; pgs stuck inactive; pgs stuck unclean
64 PG's per pool shouldn't cause any issues while there's only 3 OSD's. It'll be something to pay attention to if a lot more get added through.
Your replication setup is probably anything other than host.
You'll want to extract your crush map then decompile it and see if your "step" is set to osd or rack.
If it's not host then change it to that and pull it in again.
Check the docs on crush maps http://ceph.com/docs/master/rados/operations/crush-map/ for more info.

Try increasing the placement groups for pools
ceph osd pool set data pg_num 128
ceph osd pool set data pgp_num 128
similarly for other 2 pools as well.
