Sometimes you try to unmount a disk partition or mounted CD/DVD disk or device, which is accessed by other users, then you will get an error "umount: /xxx: device is busy". However, Linux or FreeBSD comes with the fuser command to kill forcefully mounted partition. For example, you can kill all processes accessing the file system mounted at /nas01 using the fuser command.
