Hmmm... Cycling init levels? :)

init 1
<Ctrl-D> for normal startup

Or... have you tried killing the unrecoverable processes?
kill[all] (-9) (pid|name)

As to unmounting the dead volume.. find out which processes think
they've got open files on it, using lsof, and kill those processes, then
try unmounting.
