It never works when I needed it either. Use fuser and/or lsof to find out which process still has a file open on that FS and try to stop that process 1st.

yes as Zaxxon mentioned

Examples

1. To list the process numbers of local processes using the /etc/passwd file, enter:

fuser /etc/passwd

2. To list the process numbers and user login names of processes using the /etc/filesystems file, enter:

fuser -u /etc/filesystems

3. To terminate all of the processes using a given file system, enter:

fuser -k -x -u -c /dev/hd1

or

fuser -kxuc /home

Either command lists the process number and user name, and then terminates each process that is using the /dev/hd1 (/home) file system. Only the root user can terminate processes that belong to another user. You might want to use this command if you are trying to unmount the /dev/hd1 file system and a process that is accessing the /dev/hd1 file system prevents this.
4. To list all processes that are using a file which has been deleted from a given file system, enter:

fuser -d /usr

and for AIX lsof see here
