[ceph-users] pg_num as power of two adjustment: only downwards?

Hi, After upgrading to ceph 14.2.8 I started getting the "1 pool(s) have non-power-of-two pg_num" warning. The offending pool had 100 pgs. I tried to adjust it to 128 but it didn't work: # ceph osd pool set default.rgw.offending pgp_num 128 Error EINVAL: specified pgp_num 128 > pg_num 100 It only worked downwards: # ceph osd pool set default.rgw.offending pgp_num 64 set pool 7 pgp_num to 64 Is that expected? And having reduced my pg_num to 64 (isn't it to small?) should I be prepared for problems in the future? Regards, Rodrigo Severo
