SUMMARY: Forceful unmount of Filesystem.

Thanks to all who replied.

A umount -f will bring the file system down.

Or to copy Dan Burton:

You should be able to force the umount with -f.  However you should be
careful with this.  It's very easy to snap legitimate filehandles this way
and screw stuff up.  First, try as best you can to nicely close down any
processes that might be accessing that filesystem, then do

sync; umount -f <your_filesystem_here>

Putting the sync on the same line as the umount will make them as atomic as
possible, to reduce the chance that some other process will open another
file on that filesystem before it gets unmounted.
