Hi, I have a new cluster with no data. Now it has 44 osd and my goal is to increase in the next months to reach a total of 88 osd.
My pgmap is: pgmap v841: 8640 pgs: 8640 active+clean; 8730 bytes data, 1733 MB used, 81489 GB / 81491 GB avail 2880 PG each for data, metadata and rbd pools This value was set by mkcephfs Chatting on IRC channel, it was told me to calculate 100 pg per Osd and round to near power-of-2 So in my case would be 8192 PG for each pool, right? My question: Knowing to have to double the number of osd, is it advisable to increase pg_num right now with the following commands? ceph osd pool set data pg_num 8192 --allow-experimental-feature ceph osd pool set metadata pg_num 8192 --allow-experimental-feature ceph osd pool set rbd pg_num 8192 --allow-experimental-feature Thanks -- Marco Aroldi _______________________________________________ ceph-users mailing list ceph-users@lists.ceph.com http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
