A share network must be able to contain multiple subnets that each correspond to a different Availability Zone

Registered by Goutham Pacha Ravi on 2016-04-11

Share networks in Manila currently support a single neutron/nova-network ID and single neutron/nova-network subnet each. We are seeing use cases (ex: Share Replication in DHSS=True mode) in Manila where a single network must support multiple subnets. These subnets must correspond to the configured availability zones.
