Re: Advice on balancing data across OSDs

Hi Joseph,

Here's some of the larger pools. Notable the largest (pool 51, 32 TiB
CephFS data) doesn't have the highest number of PGs.

POOL                   ID  PGS   STORED  OBJECTS     USED  %USED  MAX AVAIL
pool28                 28  256  9.9 TiB    2.61M   30 TiB  43.28     13 TiB
pool29                 29  256  9.5 TiB    2.48M   28 TiB  42.13     13 TiB
pool36                 36  128  6.0 TiB    1.58M   18 TiB  31.67     13 TiB
pool39                 39  256   20 TiB    5.20M   60 TiB  60.37     13 TiB
pool43                 43   32  1.9 TiB  503.92k  5.7 TiB  12.79     13 TiB
pool46                 46   32  1.3 TiB  236.34k  3.9 TiB   9.14     13 TiB
pool47                 47  128  4.0 TiB    1.04M   12 TiB  23.35     13 TiB
pool51                 51  128   32 TiB   32.47M   55 TiB  58.30     26 TiB
pool53                 53  128  3.3 TiB  864.88k  9.9 TiB  20.21     13 TiB
pool57                 57  128   14 TiB    3.55M   21 TiB  34.80     26 TiB

It does sounds like I need to increase that, but I had assume the
autoscaler would have produced a warning if that was the case... it
certainly has for some pools in the past, and I've adjusted as per its
recommendation.
