Title:
  shared filesystem drivers never disconnect

Status in Cinder:
  Invalid
Status in OpenStack Compute (nova):
  Confirmed

Bug description:
  While refactoring the NFS code and moving the higher level functions
  in to brick it was noticed that the NFS driver doesn't actually "do
  anything" on a disconnect_volume.  Understood that disconnecting NFS
  mounts is tricky, but leaving stale connections around in a large
  scale env like OpenStack seems like pretty bad practice.

  There should probably be some tracking here, eharney had a good
  suggestion of using something like a ref counter of attaches and
  perhaps an audit process could kill them all when none are in use
  anymore (I winged that a bit, he may have a better idea/description
  here).

  Also note that this issues is present in the existing Nova code base
  as well, it was just copied over in to the cinder/brick modules.
