In case of 12 OSDs for each node, and a cluster made with 18 storage nodes are you suggesting: (12*18*100) / 3 = 7200 PGs, that rounded to an exponent of 2 means 8192 ? _______________________________________________ ceph-users mailing list ceph-users@lists.ceph.com http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
