    Well, you didn't RTFM, right? :/ Go into the kernel source directory and
    read the file Documentation/filesystems/ext2.txt (ext3 is basically ext2
    with journalling) for explanations, look for the section called
    "Limitations". Most likely you have 4-kilobyte filesystem blocks, the
    maximum file size will be 2 terabytes then. Therefore it's obvious the
    kernel itself always supports large files with ext2/ext3 (ie. there's no
    need to enable LFS).

    The only problem is the userspace code. Examine /usr/include/features.h
    for relevant macros. You may have to add "-D_LARGEFILE_SOURCE
    -D_FILE_OFFSET_BITS=64" to your CFLAGS and recompile. If it's coded
    correctly it should work; I haven't tried it though. After all, I'm
    comfortable with dd & shred...
