"umount -f" option does not work. manual page says:

NAME
umount - unmount file systems
SYNOPSIS
umount [-fv] special | node
umount -a [-fv] [-h host] [-t ufs | lfs | external_type]
DESCRIPTION
The umount command calls the unmount(2) system call to remove a special
device or the remote node (rhost:path) from the file system tree at the
point node. If either special or node are not provided, the appropriate
information is taken from the fstab(5) file.
The options are as follows:
-a All of the file systems described in fstab(5) are unmounted.
-f The file system is forcibly unmounted. Active special devices
continue to work, but all other files return errors if further
accesses are attempted. The root file system cannot be forcibly
unmounted.

>How-To-Repeat:
mount test-server:/home/src/DPSS /usr/local/DPSS
cd /usr/local/DPSS
# umount /usr/local/DPSS
umount: /usr/local/DPSS: Device busy
# umount -f /usr/local/DPSS
umount: /usr/local/DPSS: Device busy
# umount -f test-server:/home/src/DPSS
umount: /usr/local/DPSS: Device busy
