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.

Important

In order to use share networks, the share type you choose must have the extra specification driver_handles_share_servers set to True.

Create share networks

  1. Create a share network.

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

    Note

    When creating a share network, a default share network subnet is automatically created. 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. You can optionally specify an availability zone during creation:

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

    $ openstack share network show sharenetwork1

    Note

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

    Note

    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.

Add security service/s

  1. Add a pre existent security service in a given share network.

    $ openstack share network set sharenetwork1 \
        --new-security-service my_sec_service
    $ openstack share security service list --share-network sharenetwork1
    +--------------------------------------+----------------+--------+------+
    | ID                                   | Name           | Status | Type |
    +--------------------------------------+----------------+--------+------+
    | cf36c739-7d59-4321-90f8-ad3d33b4379d | my_sec_service | new    | ldap |
    +--------------------------------------+----------------+--------+------+
    

Note

Since API version 2.63, manila supports adding security services to share networks that already are in use, depending on the share network’s support. The share network entity now contains a field called security_service_update_support which holds information whether all resources built within it can hold such operation. Before starting the operation to actually add the security service to a share network that is being used, a check operation must be triggered. See subsection.

List share network security services

  1. List all the security services existent in a share network.

    $ openstack share security service list --share-network sharenetwork1
    +--------------------------------------+----------------+--------+------+
    | ID                                   | Name           | Status | Type |
    +--------------------------------------+----------------+--------+------+
    | cf36c739-7d59-4321-90f8-ad3d33b4379d | my_sec_service | new    | ldap |
    +--------------------------------------+----------------+--------+------+
    

Remove a security service from a share network

  1. Remove a security service from a given share network.

    $ openstack share network unset sharenetwork1 \
       --security-service my_sec_service
    

Delete share networks

  1. Delete a share network.

    $ openstack share network delete sharenetwork1
    

Update share network security service check (Since API version 2.63)

  1. Check if the update for security services of the same type can be performed:

    $ openstack share network set sharenetwork1 \
       --current-security-service my_sec_service \
       --new-security-service my_sec_service_updated \
       --check-only
    
    Security service my_sec_service can be replaced with security service my_sec_service_updated on share network sharenetwork1.
    

Now, the request to update a share network security service should be accepted.

Update share network security services (Since API version 2.63)

  1. Replaces one security service for another of the same type.

    $ openstack share network set sharenetwork1 \
        --current-security-service my_sec_service \
        --new-security-service my_sec_service_updated
    $ openstack share security service list --share-network sharenetwork1
    +--------------------------------------+------------------------+--------+------+
    | ID                                   | Name                   | Status | Type |
    +--------------------------------------+------------------------+--------+------+
    | b940b445-f727-42b3-bc08-d509cd17c7c9 | my_sec_service_updated | new    | ldap |
    +--------------------------------------+------------------------+--------+------+
    

Note

The share network entity now contains a field called security_service_update_support which holds information whether all resources built within it can hold such operation. In order to update security services in share networks that currently contain shares, an operation to check if the operation can be completed must be performed. See subsection.

Add share network security service check (Since API version 2.63)

  1. Check if it is possible to add a security service to a share network:

    $ openstack share network set sharenetwork1 \
       --new-security-service my_sec_service \
       --check-only
    
    Security service my_sec_service can be added to share network sharenetwork1.
