You can change the pg numbers on the fly with
ceph osd pool set {pool_name} pg_num {value}
ceph osd pool set {pool_name} pgp_num {value}

Subject: [ceph-users] Is it possible to change the pg number after adding new
osds?
According to the doc, the pg numbers should be enlarged for better read/write
balance if the osd number is increased.
But seems the pg number cannot be changed on the fly. It's fixed when the pool
is created. Am I right?
