Hi,
I failed to increase pg_num / pgp_num on pools ssd to 1024:
root@ld3976:~# ceph osd pool get ssd pg_num
pg_num: 512
root@ld3976:~# ceph osd pool get ssd pgp_num
pgp_num: 512
root@ld3976:~# ceph osd pool set ssd pg_num 1024
root@ld3976:~# ceph osd pool get ssd pg_num
pg_num: 512
When I check autoscale-status is shows PG_NUM=1024 for pool ssd.
root@ld3976:~# ceph osd pool autoscale-status
POOL SIZE TARGET SIZE RATE RAW CAPACITY RATIO

ssd 1711G 2.0 27771G
0.1233 1.0 1024 off
I disabled pg-autoscale just today due to issues with MGR service (see
here <https://tracker.ceph.com/issues/42971>).
How can I increase pg_num / pgp_num on pools ssd?
THX
