Hi,

I do:

umount /hda14

and get:

umount: /hda14: device is busy
umount: /hda14: device is busy


Is there a way of finding out *why* it is busy? Obviously it is linked 
to someplace, but where?

Thanks!

Try mount with no arguments.  It lists mounted mount points.
    

I am embarrassed to admit that many times my cli is sitting in the very
directory I'm trying to umount.

for example.

andrew@basement:~$ mount
[...]
/dev/hdb7 on /home type ext3 (rw)
[...]
andrew@basement:~$ sudo umount /home
Password:
umount: /home: device is busy
umount: /home: device is busy


Its happened more than once. :)

  To view process which use /home, Use fuser command

$> fuser /home

if you want to kill process use
$> fuser -k /home

and then you can umount fine.
