Create and manage share networks

A share network stores network information to create and manage shares. A share network provides a way to designate a network to export shares upon. In the most common use case, you can create a share network with a private OpenStack (neutron) network that you own. If the share network is an isolated network, manila can provide hard guarantees of network and data isolation for your shared file systems in a multi-tenant cloud. In some clouds, however, shares cannot be exported directly upon private project networks; and the cloud may have provider networks that are designated for use with share networks.

In either case, as long as the underlying network is connected to the clients (virtual machines, containers or bare metals), there will exist a direct path to communicate with shares exported on the share networks.

Create share networks

  1. Create a share network.

    $ manila share-network-create \
       --name sharenetwork1 \
       --description "Share Network created for demo purposes" \

    Note

    Since API version 2.51, a share network is able to span multiple subnets in different availability zones and the network information will be stored on each subnet. To accommodate adding multiple subnets, the share network create command was updated to accept an availability zone as parameter. This parameter will be used in the share network creation process which also creates a new subnet. If you do not specify an availability zone, the created subnet will be considered default by the Shared File Systems service. A default subnet is expected to be available in all availability zones of the cloud. So when you are creating a share network, the output will be similar to:

    $ manila share-network-create \
       --name sharenetwork1 \
       --description "Share Network created for demo purposes" \
       --availability-zone manila-zone-0

    Note

    You cannot update the neutron_net_id and neutron_subnet_id of a share network that has shares exported onto it.

    Note

    From API version 2.51, updating the neutron_net_id and neutron_subnet_id is possible only for a default subnet. Non default subnets cannot be updated after they are created. You may delete the subnet in question, and re-create it. The output will look as shown below:

    $ manila share-network-update sharenetwork1 \
       --neutron-net-id a27160ca-5595-4c62-bf54-a04fb7b14316 \
