Creating shares with Shared File Systems Option 1 (DHSS = False)
----------------------------------------------------------------

Create a share type
-------------------

Disable DHSS (``driver_handles_share_servers``) before creating a share using
the LVM driver.

#. Source the admin credentials to gain access to admin-only CLI commands:

   .. code-block:: console

      $ . admin-openrc

#. Create a default share type with DHSS disabled. A default share type will
   allow you to create shares with this driver, without having to specify
   the share type explicitly during share creation.

   .. code-block:: console

      $ manila type-create default_share_type False
      +----------------------+--------------------------------------+
      | Property             | Value                                |
      +----------------------+--------------------------------------+
      | required_extra_specs | driver_handles_share_servers : False |
      | Name                 | default_share_type                   |
      | Visibility           | public                               |
      | is_default           | -                                    |
      | ID                   | 3df065c8-6ca4-4b80-a5cb-e633c0439097 |
      | optional_extra_specs | snapshot_support : True              |
      +----------------------+--------------------------------------+

   Set this default share type in ``manila.conf`` under the ``[DEFAULT]``
   section and restart the ``manila-api`` service before proceeding.
   Unless you do so, the default share type will not be effective.

   .. note::

      Creating and configuring a default share type is optional. If you wish
      to use the shared file system service with a variety of share types,
      where each share creation request could specify a type, please refer to
      the Share types usage documentation `here
      <http://docs.openstack.org/admin-guide/shared-file-systems-share-types.html>_`.

Create a share
--------------

#. Source the ``demo`` credentials to perform
   the following steps as a non-administrative project:

   .. code-block:: console

      $ . demo-openrc

#. Create an NFS share. Since a default share type has been created and
   configured, it need not be specified in the request.

   .. code-block:: console

      $ manila create NFS 1 --name share1

Mount the share on a compute instance
-------------------------------------

#. Log into your compute instance and create a folder where the mount will
   be placed:

#. Mount the NFS share in the compute instance using the export location of
   the share:

   .. code-block:: console

      # mount -vt nfs 10.0.0.41:/var/lib/manila/mnt/share-8e13a98f-c310-41df-ac90-fc8bce4910b8 ~/test_folder
