Unless I misunderstand this, three OSD servers, each with eight OSD's, for a total of 24 OSD's. The formula is(as I understand it): Total PG's = 100 x 24/3. And, I see an error in my simple math! I should have said 800. Is that more what you were expecting?

How did get 600 PGs from 24 OSDs and a replication factor of 3? /pm _______________________________________________ ceph-users mailing list [email protected] http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com _______________________________________________ ceph-users mailing list [email protected] http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
