Hans,
I made a big change in my staging cluster before, I set a pool pg_num
from 8 to 2048, it cased the cluster available for a long time :(

I don't think it might lead to more client slow requests if you set it
to 4096 in one step, since there is a cap on how many
recovery/backfill requests there can be per OSD at any given time.
I am not sure though, but I am happy to be proved wrong by the senior
members in this list :)

Hi guys,
I have a rbd pool pg_num 2048, I want to change it to 4096, how can I
do this?
If I change it directly to 4096, it may cause the client slow requests,
What the better step size should be?
Thanks,
Kern
