[openstack-dev] [nova] Why doesn't the libvirt scality volume driver implement disconnect_volume?

I'm going to make the connect_volume and disconnect_volume methods for 
the libvirt volume drivers abstract methods because of a recent 
regression [1] but when I'm looking at the Scality volume driver it 
doesn't implement the disconnect_volume method. Does it just never 
detach volumes or....?

Looks like it was added 4 years ago [2] and I don't see any mention of 
the lack of disconnect in there.

Does this thing even work? It was added before we ever actually cared 
about testing vendor drivers. Can someone from Scality clarify please?
