neutron network multi segment ip version

[Maurice Escher]

Hi,

I try running pike with neutron binding in a multi segment network.

In this case the neutron network info is stored only at the binding
and ip_version is None in https://github.com/openstack/manila/blob/stable/pike/manila/network/neutron/neutron_network_plugin.py#L214.
Which leads to a NetworkBadConfigurationException "Can not find any IP address with configured IP version None in share-network" in https://github.com/openstack/manila/blob/stable/pike/manila/network/neutron/neutron_network_plugin.py#L179

I suggest to fix with a fallback ip version or by taking the configured version.

Thanks,
Maurice

Just to be explicit: did this work in Ocata, i.e. is this a Pike regression?

Yes, it worked before the commit https://github.com/openstack/manila/commit/2b40e5618f2c1039bbbbd1a3e31b72e104b5436b

    NeutronBindNetworkPlugin: fix multi segment neutron data save.

    Neutron subnet data can be obtained directly and is needed to get
    ip_version for port creation. Network data needs to wait for port
    binding.
    Fixes 2b40e5618f2c1039bbbbd1a3e31b72e104b5436b error:
    "Can not find any IP address with configured IP version None in
    share-network".
