Folks, I am building new ceph storage and i have currently 8 OSD total (in future i am going to add more)
Based on official document I should do following to calculate Total PG 8 * 100 / 3 = 266 ( nearest power of 2 is 512 ) Now i have 2 pool at present in my ceph cluster (images & vms) so per pool PG would be 8 * 100 / 3 / 2 = 133 ( nearest power of 2 is 256 ) so my pg_num and pgp_num both would be 256, am i correct? Lets say after 1 week i add 8 more OSD in cluster then should i need to re-run same calculation with 16 OSD and adjust all my pool pg_num & pgp_num ? is it safe to do in production? _______________________________________________ ceph-users mailing list ceph-users@lists.ceph.com http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
