Increased number of PGs in multiple pools in a production cluster on 12.2.2 recently - zero issues.
CEPH claims that increasing pg_num and pgp_num are safe operations, which are essential for it's ability to scale, and this sounds pretty reasonable to me. [1]

Hi,Initial PG count was not properly planned while setting up the cluster, so now there are only less than 50 PGs per OSDs.What are the best practises to increase PG number of a pool ?We have replicated pools as well as EC pools.Or is it better to create a new pool with higher PG numbers?Karun
