Hello, I would like to build a small cluster with 20 disks to start but in the future would like to gradually increase it to maybe 200 disks. Is it better to fix the number of PGs in the pool from the beginning or is it better to start with a small number and then gradually change the number of PGs as the system grows ? Is the act of changing the number of PGs in a running cluster something that can be done regularly ?
Cheers /Maged
