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.
