Hi, consider following values for a pool:
Size = 3 OSDs = 400 %Data = 100 Target PGs per OSD = 200 (This is default) The PG calculator generates number of PGs for this pool as : 32768. Questions: 1. The Ceph documentation recommends around 100 PGs/OSD, whereas the calculator takes 200 as default value. Are there any changes in the recommended value of PGs/OSD? 2. Under "notes" it says: "Total PG Count" below table will be the count of Primary PG copies. However, when calculating total PGs per OSD average, you must include all copies. However, the number of 200 PGs/OSD already seems to include the primary as well as replica PGs in a OSD. Is the note a typo mistake or am I missing something? thanks, Sreenath _______________________________________________ ceph-users mailing list ceph-users@lists.ceph.com http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
