So, my pool size has increased to a point where the autoscaler did suggest an
increase of pg_num (from 100 to 512). Autoscaler mode is “on”, but no change
happens..

Hi Burkhard,
I tried using the autoscaler, however it did not give a suggestion to resize
pg_num. Since my pg_num is not a power of 2, I wanted to fix that first,
manually, to only realize that it didn’t work.
Because changing pg_num manually did not work, I am not convinced that the

No, it’s pg_num first, then pgp_num.
Found the problem, and still slowly working on fixing it.
I upgraded from mimic to nautilus, but forgot to restart the OSD daemons for 2
of the OSDs. “ceph osd tell osd.* version” told me which OSDs had a stale
version.
Then it was just a matter of restart
You don't have to increase pgp_num first?

I have the same problem (nautilus installed), but the proposed command gave me
an error:
# ceph osd require-osd-release nautilus
Error EPERM: not all up OSDs have CEPH_FEATURE_SERVER_NAUTILUS feature

I created my cluster with mimic and then upgraded to nautilus.
What would be my next step?

Good to know, I haven't gotten to Nautilus yet.

In Nautilus just pg_num is sufficient for both increases and decreases.

I believe he needs to increase the pgp_num first, then pg_num.

I ran into this recently. Try running "ceph osd require-osd-release
nautilus". This drops backwards compat with pre-nautilus and allows
changing settings.

Hi all,
I am using ceph 14.2.1 (Nautilus)
I am unable to increase the pg_num of a pool.
I have a pool named Backup, the current pg_num is 64 : ceph osd pool get
Backup pg_num => result pg_num: 64
And when I try to increase it using the command
ceph osd pool set Backup pg_num 512 => result "
12 matches
