The ``default_share_type`` option specifies the default share type to
be used when shares are created without specifying the share type in
the request. The default share type that is specified in the
configuration file has to be created with the necessary required
extra-specs (such as ``driver_handles_share_servers``) set
appropriately with reference to the driver mode used. This is further
explained in the section discussing the setup and configuration of the

Creating shares with Shared File Systems Option 2 (DHSS = True)
---------------------------------------------------------------
Before being able to create a share, manila with the generic driver and
the DHSS (``driver_handles_share_servers``) mode enabled requires the
definition of at least an image, a network and a share-network for being
used to create a share server. For that `back end` configuration, the share
server is an instance where NFS shares are served.
.. note::
This configuration automatically creates a cinder volume for every share.
The cinder volumes are attached to share servers according to the
definition of a share network.
#. Source the admin credentials to gain access to admin-only CLI commands:
.. code-block:: console
$ . admin-openrc.sh
#. Create a default share type with DHSS enabled. A default share type will
allow you to create shares with this driver, without having to specify
the share type explicitly during share creation.

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 manila share server image in the Image service. You may skip this
step and use any existing image. However, for mounting a share, the service
image must contain the NFS packages as appropriate for the operating system.
Whatever image you choose to be the service image, be sure to set the
configuration values ``service_image_name``, ``service_instance_flavor_id``,
``service_instance_user`` and ``service_instance_password`` in
``manila.conf``.
.. note::
Any changes made to ``manila.conf`` while the ``manila-share`` service
is running will require a restart of the service to be effective.
.. note::
As an alternative to specifying a plain-text
``service_instance_password`` in your configuration, a key-pair may be
specified with options ``path_to_public_key`` and
``path_to_private_key`` to configure and allow password-less SSH access
between the `share node` and the share server/s created.

#. Configure user access to the new share before attempting to mount it via
the network:
.. important ::
The image used for launching an instance and mounting a share must have
the NFS packages provided by the distro. Example: The cirros image
created at the image service section is not enough.
.. important ::
Use an instance that is connected to the private network used to create
the share-network.
.. code-block:: console
$ manila access-allow demo-share1 ip INSTANCE_PRIVATE_NETWORK_IP
Mount the share from an instance
--------------------------------
#. Create a folder where the mount will be placed:
.. code-block:: console
$ mkdir ~/test_folder
#. Mount the NFS share in the instance using the export location of the share:
.. code-block:: console
$ mount -v 10.254.0.6:/shares/share-0bfd69a1-27f0-4ef5-af17-7cd50bce6550 ~/test_folder
