Goutham Pacha Ravi bc4712e35e Manila install guide: Fix wrong instructions
Previously only the DHSS=True mode was documented
in post install steps. The assumption that the generic driver
was being configured existed in other places as well.

* add DHSS=False documentation as necessary with the
   LVM driver.
* correct assumptions in other places to clarify usage
   of appropriate share driver modes.

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

Allow access to the share
-------------------------
#. Configure access to the new share before attempting to mount it via
the network. The compute instance (whose IP address is referenced by the
INSTANCE_IP below) must have network connectivity to the network specified
in the share network.
.. code-block:: console
$ manila access-allow share1 ip INSTANCE_IP

+--------------+--------------------------------------+
Mount the share on a compute instance
-------------------------------------
#. Log into your compute instance and create a folder where the mount will
be placed:
.. code-block:: console
$ mkdir ~/test_folder
#. 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
