Description

We just updated our cluster from 14.2.1 to 14.2.22. Now (in addition two a few more) a new warning appears which we have not seen before:

4 pool(s) have non-power-of-two pg_num

I checked all 7 pools in the cluster using "sudo ceph osd pool get <POOLNAME> pg_num" and all have power-of-two pg_nums except "device_health_metrics". I guess the latter one is okay to have only 1 pg.

@Martin H, can you please attach the monitor log?

#2 Updated by Martin H. about 2 years ago

Well, turns out (as a non-native English speaker) I confused "power of two" with "divisible by two"..

So my pg nums are really not power-of-two and I will try to adjust them. Sorry for the noise. _
