Hello!
When setting up Ceph Filesystem at least two RADOS pools, one for data and one 
for metadata, are required.
Example:
$ ceph osd pool create cephfs_data <pg_num>
$ ceph osd pool create cephfs_metadata <pg_num>

My question is regarding the value <pg_num>:
Should this value be equal for data an metadata?
Is my assumption correct that the value <pg_num> is related to the available 
"size" of the pool? Means, if I want to increase the available storage in a 
pool I should increase <pg_num> accordingly?

I understood that the max <pg_num> is: OSDs * 100 / number of replicas.

THX
