Is it good idea to make a metadata pool smaller?
Yes, the metadata pool usually has small amount of data stored. I'm suspecting it will be OK to start with 32 or 64 PGs for ceph_metadata, and double the PG number each case the pool utilization will be high (or will be proposed by ' ceph -s '). The PG number increment can be done on the fly.
