Re: Placement Groups

After doing a little more digging, I see each default pool has 2624 PGs.

pool 0 'data' rep size 3 crush_ruleset 0 object_hash rjenkins pg_num 2624 pgp_num 2624 last_change 38 owner 0 crash_replay_interval 45

pool 1 'metadata' rep size 2 crush_ruleset 1 object_hash rjenkins pg_num 2624 pgp_num 2624 last_change 1 owner 0

pool 2 'rbd' rep size 2 crush_ruleset 2 object_hash rjenkins pg_num 2624 pgp_num 2624 last_change 1 owner 0

In my ceph.conf file, I set the options under the [osd] section:

osd pool default pg num = 133

osd pool default pgp num = 133

And yet, after running a mkcephfs, when I do a ceph -s it shows:

pgmap v23972: 7872 pgs: 7872 active+clean;

I should also mention I have 40 OSDs, with a replica level of 3. Am I misunderstanding something, or did it ignore that option?
