    If your df differs from du -csm /mountpoint, check for deleted files still opened (so still on disk, seen by df, but not du) with lsof :
    lsof |grep deleted

    For an online disk usage report you can also try http://www.diskreport.net
    With periodic reports you can get graphs of size changes for each directory, very usefull to find growing files
