[ceph-users] Re: How to change the pg numbers

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 :) Hans On 8/18/20 10:23 AM, norman wrote:

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,
