    I know of one bug in it which will thoroughly smash user data beyond
    recognition - it happens when you resize RAID-5 arrays on disks that are
    not of equal size. Should be easy to fix, if one tried :)

    If you want it in the kernel doing hot-resizing, you probably want to
    add some sort of 'progress log' so that one can resume the
    reconfiguration after a reboot - that should be doable, just isn't done
    yet.

    Right now it's entirely a user-space tool and it is not integrated with
    the MD code to make it do hot-reconfiguration - integrating it with DM
    and MD would make it truely useful.
