Ceph default configuration with 12 osd's.

Information from astute:
storage:
  iser: false
  volumes_ceph: true
  per_pool_pg_nums:
    compute: 256
    default_pg_num: 64
    volumes: 512
    images: 64
    backups: 128
    ".rgw": 128
  objects_ceph: true
  ephemeral_ceph: true
  volumes_lvm: false
  images_vcenter: false
  osd_pool_size: '3'
  pg_num: 64
  images_ceph: true
  metadata:
    weight: 60
    label: Storage

But the deployed configuration is:
ceph osd dump | awk '/pool/ { print $3 " " $14 }'
'data' 64
'metadata' 64
'rbd' 64
'images' 64
'volumes' 64
'backups' 64
'.rgw.root' 64
'.rgw.control' 64
'.rgw' 64
'.rgw.gc' 64
'.users.uid' 64
'compute' 64
'.users' 64

[Dmitry Klenov (dklenov)]

Pawel, can you please also attach diagnostic snapshot?

[Pawel Stefanski (pejotes)]

After next deployment I will attach it.

This bug should be patched in next 7.0 update.

As a fix procedure for already deployed environment, pg_num can be changed by issuing.
ceph osd pool set {pool-name} pg_num {pg_num}

[Roman Podoliaka (rpodolyaka)]

Pawel, can we close this bug now?

[Kyrylo Galanov (kgalanov)]

Hi,

The issue may be caused by the fact that patch https://review.openstack.org/#/c/204811/12 was not merged.
