Share network is an entity that encapsulates interaction with the OpenStack
|
|
Networking service. If the share driver that you selected runs in a mode
|
|
requiring Networking service interaction, specify the share network when
|
|
creating a new share network.

|
How to create share network
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
To list networks in a tenant, run:
|
|
|
|
.. code-block:: console
|
|
|
|
$ neutron net-list
|
|
+--------------+---------+---------------------------------------+
|
|

A share network stores network information that share servers can use where
|
|
shares are hosted. You can associate a share with a single share network.
|
|
When you create or update a share, you can optionally specify the ID of a share
|
|
network through which instances can access the share.
|
|
|
|
When you create a share network, you can specify only one type of network:
|
|
|
|
- OpenStack Networking (neutron). Specify a network ID and subnet ID.
|
|
In this case ``manila.network.nova_network_plugin.NeutronNetworkPlugin``
|
|
will be used.
|
|
|
|
- Legacy networking (nova-network). Specify a network ID.
|
|
In this case ``manila.network.nova_network_plugin.NoveNetworkPlugin``
|
|
will be used.
|
|
|
|
For more information about supported plug-ins for share networks, see
|
|
:ref:`shared_file_systems_network_plugins`.
|
|
|
|
A share network has these attributes:
|
|
|
|
- The IP block in Classless Inter-Domain Routing (CIDR) notation from which to
|
|
allocate the network.
|
|
|
|
- The IP version of the network.
|
|
|
|
- The network type, which is `vlan`, `vxlan`, `gre`, or `flat`.
|
|
|
|
If the network uses segmentation, a segmentation identifier. For example, VLAN,
|
|
VXLAN, and GRE networks use segmentation.
|
|
|
|
To create a share network with private network and subnetwork, run:
|
|
|
|
.. code-block:: console
|
|
|
|
$ manila share-network-create --neutron-net-id 5ed5a854-21dc-4ed3-870a-117b7064eb21 \
|
|
--neutron-subnet-id 74dcfb5a-b4d7-4855-86f5-a669729428dc --name my_share_net --description "My first share network"

|
|
|
|
The ``segmentation_id``, ``cidr``, ``ip_version``, and ``network_type``
|
|
share network attributes are automatically set to the values determined by the
|
|
network provider.
|
|
|
|
To check the network list, run:
|
|
|
|
.. code-block:: console
|
|
|
|
$ manila share-network-list
|
|
+--------------------------------------+--------------+
|
|
| id | name |
|

|
|
|
|
If you configured the generic driver with ``driver_handles_share_servers =
|
|
True`` (with the share servers) and already had previous operations in the Shared
|
|
File Systems service, you can see ``manila_service_network`` in the neutron
|
|
list of networks. This network was created by the generic driver for internal
|
|
use.
|
|
|
|
.. code-block:: console
|
|
|
|
$ neutron net-list
|
|

You also can see detailed information about the share network including
|
|
``network_type``, and ``segmentation_id`` fields:
|
|
|
|
.. code-block:: console
|
|
|
|
$ neutron net-show manila_service_network

|
|
|
You also can add and remove the security services from the share network.
