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 2 (DHSS = True)

Before being able to create a share, manila with the generic driver and

||||
definition of at least an image, a network and a share-network for being

server is an instance where NFS shares are served.

This configuration automatically creates a cinder volume for every share.

Creating shared file systems

~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
Creating and using shared file systems
|
||||
======================================
|
||||
|
||||
Before being able to create a share, manila with the generic driver and
|
||||
the DHSS 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/CIFS shares are served.
|
||||
Depending on the option chosen while installing the share node (Option with
|
||||
share server management and one without); the steps to create and use your
|
||||
shared file systems will vary. When the Shared File Systems service handles
|
||||
the creation and management of share servers, you would need to specify the
|
||||
``share network`` with the request to create a share. Either modes will vary
|
||||
in their respective share type definition. When using the driver mode with
|
||||
automatic handling of share servers, a service image is needed as specified
|
||||
in your configuration. The instructions below enumerate the steps for both
|
||||
driver modes. Follow what is appropriate for your installation.
|
||||
|
||||
.. 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.

#. 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
