Hi Zhangleiqiang, I think it's not approved because it has not been set to a series goal by the drafter. I don't have permission myself to change the series goal, but I would recommend going into the #openstack-cinder IRC channel and ask for the BP to be set for the Juno release assuming there is a good approach. We'd also need a contributor to take on this task. I think it would be good to use the os-hosts extension which can be found in cinder.api.contrib.hosts and add the additional response information there. It already lists total volume/snapshot count and capacity used [1].
