-Regions
-=======
-
-In Ceph v0.67 and beyond, Ceph Object Gateway supports federated deployments and
-a global namespace via the notion of regions. A region defines the geographic
-location of one or more Ceph Object Gateway instances within one or more zones.
-
-
-Configuring regions differs from typical configuration procedures, because not
-all of the settings end up in a Ceph configuration file. In Ceph v0.67 and
-beyond, you can list regions, get a region configuration and set a region
-configuration.
-
-
-List Regions
-------------
-
-A Ceph cluster contains a list of regions. To list the regions, execute::
-
- sudo radosgw-admin region list
-
-The ``radosgw-admin`` returns a JSON formatted list of regions.
-
-.. code-block:: javascript
-
- { "default_info": { "default_region": "default"},
- "regions": [
- "default"]}
-
-
-Get a Region Map
-----------------
-
-To list the details of each region, execute::
-
- sudo radosgw-admin region-map get
-
-
-.. note:: If you receive a ``failed to read region map`` error, run
- ``sudo radosgw-admin region-map update`` first.
-
-
-Get a Region
-------------
-
-To view the configuration of a region, execute::
-
- radosgw-admin region get [--rgw-region=<region>]
-
-The ``default`` region looks like this:
-
-.. code-block:: javascript
-
- {"name": "default",
- "api_name": "",
- "is_master": "true",
- "endpoints": [],
- "hostnames": [],
- "master_zone": "",
- "zones": [
- {"name": "default",
- "endpoints": [],
- "log_meta": "false",
- "log_data": "false"}
- ],
- "placement_targets": [
- {"name": "default-placement",
- "tags": [] }],
- "default_placement": "default-placement"}
-
-Set a Region
-------------
-
-Defining a region consists of creating a JSON object, specifying at least the
-required settings:
-
-#. ``name``: The name of the region. Required.
-
-#. ``api_name``: The API name for the region. Optional.
-
-#. ``is_master``: Determines if the region is the master region. Required.
- **note:** You can only have one master region.
-
-#. ``endpoints``: A list of all the endpoints in the region. For example,
- you may use multiple domain names to refer to the same region. Remember to
- escape the forward slashes (``\/``). You may also specify a
- port (``fqdn:port``) for each endpoint. Optional.
-
-#. ``hostnames``: A list of all the hostnames in the region. For example,
- you may use multiple domain names to refer to the same region. Optional.
- The ``rgw dns name`` setting will automatically be included in this list.
- You should restart the ``radosgw`` daemon(s) after changing this setting.
-
-#. ``master_zone``: The master zone for the region. Optional. Uses the default
- zone if not specified. **note:** You can only have one master zone per
- region.
-
-#. ``zones``: A list of all zones within the region. Each zone has a
- name (required), a list of endpoints (optional), and whether or not the
- gateway will log metadata and data operations (false by default).
-
-#. ``placement_targets``: A list of placement targets (optional). Each
- placement target contains a name (required) for the placement target
- and a list of tags (optional) so that only users with the tag can use
- the placement target (i.e., the user's ``placement_tags`` field in the
- user info).
-
-#. ``default_placement``: The default placement target for the object
- index and object data. Set to ``default-placement`` by default. You
- may also set a per-user default placement in the user info for each
- user.
-
-To set a region, create a JSON object consisting of the required fields, save
-the object to a file (e.g., ``region.json``); then, execute the following
-command::
-
- sudo radosgw-admin region set --infile region.json
-
-Where ``region.json`` is the JSON file you created.
-
-
-.. important:: The ``default`` region ``is_master`` setting is ``true`` by
- default. If you create a new region and want to make it the master region,
- you must either set the ``default`` region ``is_master`` setting to
- ``false``, or delete the ``default`` region.
-
-
-Finally, update the map. ::
-
- sudo radosgw-admin region-map update
-
-
-Set a Region Map
-----------------
-
-Setting a region map consists of creating a JSON object consisting of one or more
-regions, and setting the ``master_region`` for the cluster. Each region in the
-region map consists of a key/value pair, where the ``key`` setting is equivalent to
-the ``name`` setting for an individual region configuration, and the ``val`` is
-a JSON object consisting of an individual region configuration.
-
-You may only have one region with ``is_master`` equal to ``true``, and it must be
-specified as the ``master_region`` at the end of the region map. The following
-JSON object is an example of a default region map.
-
-
-.. code-block:: javascript
-
- { "regions": [
- { "key": "default",
- "val": { "name": "default",
- "api_name": "",
- "is_master": "true",
- "endpoints": [],
- "hostnames": [],
- "master_zone": "",
- "zones": [
- { "name": "default",
- "endpoints": [],
- "log_meta": "false",
- "log_data": "false"}],
- "placement_targets": [
- { "name": "default-placement",
- "tags": []}],
- "default_placement": "default-placement"
- }
- }
- ],
- "master_region": "default"
- }
-
-To set a region map, execute the following::
-
- sudo radosgw-admin region-map set --infile regionmap.json
-
-Where ``regionmap.json`` is the JSON file you created. Ensure that you have
-zones created for the ones specified in the region map. Finally, update the map.
-::
-
- sudo radosgw-admin regionmap update
-
-
-Zones
-=====
-
-In Ceph v0.67 and beyond, Ceph Object Gateway supports the notion of zones. A
-zone defines a logical group consisting of one or more Ceph Object Gateway
-instances.
-
-Configuring zones differs from typical configuration procedures, because not
-all of the settings end up in a Ceph configuration file. In Ceph v0.67 and
-beyond, you can list zones, get a zone configuration and set a zone
-configuration.
-
-
-List Zones
-----------
-
-To list the zones in a cluster, execute::
-
- sudo radosgw-admin zone list
-
-
-Get a Zone
-----------
-
-To get the configuration of a zone, execute::
-
- sudo radosgw-admin zone get [--rgw-zone=<zone>]
-
-The ``default`` zone looks like this:
-
-.. code-block:: javascript
-
- { "domain_root": ".rgw",
- "control_pool": ".rgw.control",
- "gc_pool": ".rgw.gc",
- "log_pool": ".log",
- "intent_log_pool": ".intent-log",
- "usage_log_pool": ".usage",
- "user_keys_pool": ".users",
- "user_email_pool": ".users.email",
- "user_swift_pool": ".users.swift",
- "user_uid_pool": ".users.uid",
- "system_key": { "access_key": "", "secret_key": ""},
- "placement_pools": [
- { "key": "default-placement",
- "val": { "index_pool": ".rgw.buckets.index",
- "data_pool": ".rgw.buckets"}
- }
- ]
- }
-
-
-Set a Zone
-----------
-
-Configuring a zone involves specifying a series of Ceph Object Gateway pools.
-For consistency, we recommend using a pool prefix that is
-the same as the zone name. See `Pools`_ for details of configuring pools.
+Multisite Settings
+==================
-To set a zone, create a JSON object consisting of the pools, save
-the object to a file (e.g., ``zone.json``); then, execute the following
-command, replacing ``{zone-name}`` with the name of the zone::
-
- sudo radosgw-admin zone set --rgw-zone={zone-name} --infile zone.json
-
-Where ``zone.json`` is the JSON file you created.
-
-

-
-Pools
-=====
-
-Ceph zones map to a series of Ceph Storage Cluster pools.
-
-.. topic:: Manually Created Pools vs. Generated Pools
-
- If you provide write capabilities to the user key for your Ceph Object
- Gateway, the gateway has the ability to create pools automatically. This
- is convenient, but the Ceph Object Storage Cluster uses the default
- values for the number of placement groups (which may not be ideal) or the
- values you specified in your Ceph configuration file. If you allow the
- Ceph Object Gateway to create pools automatically, ensure that you have
- reasonable defaults for the number of placement groups. See
- `Pool Configuration`_ for details. See `Cluster Pools`_ for details on
- creating pools.
-
-The default pools for the Ceph Object Gateway's default zone include:
-
-- ``.rgw``
-- ``.rgw.control``
-- ``.rgw.gc``
-- ``.log``
-- ``.intent-log``
-- ``.usage``
-- ``.users``
-- ``.users.email``
-- ``.users.swift``
-- ``.users.uid``
-
-You have significant discretion in determining how you want a zone to access
-pools. You can create pools on a per zone basis, or use the same pools for
-multiple zones. As a best practice, we recommend having a separate set of pools
-for your master zone and your secondary zones in each region. When creating
-pools for a specific zone, consider prepending the region name and zone name to
-the default pool names. For example:
-
-- ``.region1-zone1.domain.rgw``
-- ``.region1-zone1.rgw.control``
-- ``.region1-zone1.rgw.gc``
-- ``.region1-zone1.log``
-- ``.region1-zone1.intent-log``
-- ``.region1-zone1.usage``
-- ``.region1-zone1.users``
-- ``.region1-zone1.users.email``
-- ``.region1-zone1.users.swift``
-- ``.region1-zone1.users.uid``
-
-
-Ceph Object Gateways store data for the bucket index (``index_pool``) and bucket
-data (``data_pool``) in placement pools. These may overlap--i.e., you may use
-the same pool for the index and the data. The index pool for default
-placement is ``.rgw.buckets.index`` and for the data pool for default placement
-is ``.rgw.buckets``. See `Zones`_ for details on specifying pools in a zone
-configuration.
