--- upgrade: - | The CIDR for the StorageNFS network in the sample network_data_ganesha.yaml file has been modified to provide more usable IPs for the corresponding Neutron overcloud StorageNFS provider network. Since the CIDR of an existing network cannot be modified, deployments with existing StorageNFS networks should be sure to customize the StorageNFS network definition to use the same CIDR as that in their existing deployment in order to avoid a heat resource failure when updating or upgrading the overcloud. fixes: - | Fixed issue in the sample network_data_ganesha.yaml file where the IPv4 allocation range for the StorageNFS network occupies almost the whole of its CIDR. If network_data_ganesha.yaml is used without modification in a customer deployment then there are too few IPs left over in its CIDR for use by the corresponding overcloud Neutron StorageNFS provider network for its overcloud DHCP service.
