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.
|
|
|
|
.. code-block:: console
|
|
|
|
$ manila type-create default_share_type 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
|
|
<https://docs.openstack.org/manila/latest/admin/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.
