    Here are the steps with options,

    1. dd if=/dev/zero of=<filename.img> bs=1M count=16

    2. mkfs.btrfs <filename.img>

    3. Corrupt the <filename.img> using 'mangle'

    4. mount -t btrfs -o loop <filename.img> <mount point>

    5. # btrfs-debug-tree <filename.img>
    Couldn't map the block 3221392384
    Couldn't read chunk root
    unable to open <filename.img>
    # btrfs-debug-tree /dev/loop0
    Couldn't map the block 3221392384
    Couldn't read chunk root
    unable to open /dev/loop0
