Share networks
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 project, run:
$ openstack network list
+--------------+---------+--------------------+
| ID | Name | Subnets |
+--------------+---------+--------------------+
| bee7411d-... | public | 884a6564-0f11-... |
| | | e6da81fa-5d5f-... |
| 5ed5a854-... | private | 74dcfb5a-b4d7-... |
| | | cc297be2-5213-... |
+--------------+---------+--------------------+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.
For more information about supported plug-ins for share networks, see
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:
$ 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"
+-------------------+--------------------------------------+
| Property | Value |
+-------------------+--------------------------------------+
| name | my_share_net |
| segmentation_id | None |

| 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:
$ manila share-network-list
+--------------------------------------+--------------+
| id | name |
+--------------------------------------+--------------+
| 5c3cbabb-f4da-465f-bc7f-fadbe047b85a | my_share_net |
+--------------------------------------+--------------+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.
