--- fixes: - | When deploying Manila CephFS NFS with cephadm, the manila share service fails to start with the error "Backend cephfsnfs supports neither IPv4 nor IPv6". This happens because the NFS Ganesha daemon fails to start for some reason, and therefore the driver never gets the location of the NFS Ganesha service that will be used as the backend. We rely on the operator to make sure the CephFS NFS cluster is available when initializing the driver. With this fix in place, we raise an exception to explicitly notify the operator and allow them to take further action.
