-Pools
-=====
-
-The Ceph Object Gateway uses several pools for its various storage needs,
-which are listed in the Zone object (see ``radosgw-admin zone get``). A
-single zone named ``default`` is created automatically with pool names
-starting with ``default.rgw.``, but a `Multisite Configuration`_ will have
-multiple zones.
-
-Tuning
-======
-
-When ``radosgw`` first tries to operate on a zone pool that does not
-exist, it will create that pool with the default values from
-``osd pool default pg num`` and ``osd pool default pgp num``. These defaults
-are sufficient for some pools, but others (especially those listed in
-``placement_pools`` for the bucket index and data) will require additional
-tuning. We recommend using the `Ceph Placement Group’s per Pool
-Calculator <http://ceph.com/pgcalc/>`__ to calculate a suitable number of
-placement groups for these pools. See
-`Pools <http://docs.ceph.com/docs/master/rados/operations/pools/#pools>`__
-for details on pool creation.
-
-Pool Namespaces
-===============
-
-.. versionadded:: Luminous
-
-Pool names particular to a zone follow the naming convention
-``{zone-name}.pool-name``. For example, a zone named ``us-east`` will
-have the following pools:
-
-- ``.rgw.root``
-
-- ``us-east.rgw.control``
-
-- ``us-east.rgw.meta``
-
-- ``us-east.rgw.log``
-
-- ``us-east.rgw.buckets.index``
-
-- ``us-east.rgw.buckets.data``
-
-The zone definitions list several more pools than that, but many of those
-are consolidated through the use of rados namespaces. For example, all of
-the following pool entries use namespaces of the ``us-east.rgw.meta`` pool::
-
- "user_keys_pool": "us-east.rgw.meta:users.keys",
- "user_email_pool": "us-east.rgw.meta:users.email",
- "user_swift_pool": "us-east.rgw.meta:users.swift",
- "user_uid_pool": "us-east.rgw.meta:users.uid",
-
