Issue

  • Using the umount command to unmount a filesystem does not work and shows an error:

    # umount /path/to/mount/point
umount: /path/to/mount/point: device is busy

# umount /path/to/mount/point
umount: /path/to/mount/point: target is busy.
        (In some cases useful info about processes that use
         the device is found by lsof(8) or fuser(1))
