Yeah, we still have no way to inspect the actual usage of image.

But we already have existing bp to impl it. https://wiki.ceph.com/Planning/Blueprints/Hammer/librbd%3A_shared_flag%2C_object_map

According to the docs, Ceph block devices are thin provisioned. But how do I
list the actual size of vm images hosted on ceph?

I do something like:
  rbd ls -l rbd

But that only lists the provisioned sizes, not the real usage.

thanks,
