I don't think we need a restart.

I was able to use "/proc/*/mounts" as James suggested to kill all the old
docker processes.  "sudo service docker kill" did not do a very good job of
shutting down cleanly!  I have now reformatted the docker partition and
updated docker so hopefully it will all get back up and running very soon!

Adding more drives to justice sounds like a very good idea :)
