Daniel Gonzalez 3e86e3deac Migrate API reference into tree 
The API Documentation team has requires [1] that
projects maintain their api-reference in-tree and
build it to the developer.openstack.org website.

This version of the API reference uses os-api-ref
and compiles API documentation close to that of
the OpenStack compute service (nova).

Share types
===========
A share type enables you to filter or choose back ends before you
create a share. A share type behaves in the same way as a Block
Storage volume type behaves.
You set a share type to private or public and manage the access to
the private share types.
When you issue a create a share type request, you can submit a
request body with either a ``share_type`` or ``volume_type``
object.
.. important::
The use of the ``volume_type`` object is deprecated but supported. It is
recommended that you use the ``share_type`` object when you create a
share type.
No matter which object type you include in the request, the API
creates both a ``volume_type`` object and a ``share_type`` object.
Both objects have the same ID. When you issue a list share types
request, the response shows both ``share_type`` and ``volume_type`` objects.
You can set share types as either public or private. By default a
share type is created as publicly accessible. Set
``share_type_access:is_public`` (``os-share-type-access:is_public``
for API versions 1.0-2.6) to ``False`` to make the share type
private.
You can manage the access to the private share types for the
different projects. You can add access, remove access, and get
information about access for a private share type.
Administrators can create share types with these extra
specifications that are used to filter back ends:
- ``driver_handles_share_servers``. Required. Defines the driver
mode for share server, or storage, life cycle management. The
Shared File Systems service creates a share server for the export
of shares.
Set to ``True`` when the share driver manages or handles the
share server life cycle.
Set to ``False`` when an administrator rather than a share driver
manages the share server life cycle.
- ``snapshot_support``. Filters back ends by whether they do or do
not support share snapshots.
Set to ``True`` to find back ends that support share snapshots.
Set to ``False`` to find back ends that do not support share
snapshots.
Administrators can also set additional extra specifications for a
share type for the following purposes:
- Filter back ends. Specify these unqualified extra specifications
in this format: ``extra_spec=value``. For example,
``netapp_raid_type=raid4``.
- Set data for the driver. Except for the special ``capabilities``
prefix, you specify these qualified extra specifications with its
prefix followed by a colon: ``vendor:extra_spec=value``. For
example, ``netapp:thin_provisioned=true``.
The scheduler uses the special ``capabilities`` prefix for
filtering. The scheduler can only create a share on a back end that
reports capabilities that match the un-scoped extra-spec keys for
the share type. For details, see `Capabilities and Extra-Specs <htt
p://docs.openstack.org/developer/manila/devref/capabilities_and_ext
ra_specs.html>`_.
Each driver implementation determines which extra specification
keys it uses. For details, see the documentation for the driver.
An administrator can use the ``policy.json`` file to grant
permissions for share type creation with extra specifications to
other roles.
