That doesn't work. Just results in a failed: device busy message.
That 'device' no longer exists, it was shutdown, removed from the network, 
it's gone, it's no-more. So it is not possible for it to be busy. I realize I 
made a mistake by not unmounting this mountpoint prior to taking it down, now 
I would like to resolve this without a reboot.
