    Fair question.
    I want it to work with "standard" partition tables such as MSDOS
    partitions etc.
    I would like to be able to take a single drive that is being used and
    has partitions on it, and to add an identical drive beside it, mirror
    them, and get a mirrored pair that looked much like the original
    drive.
    There are issues with the raid superblock but assuming they can be
    solved, I want partitioning to work easily.

    Can LVM work happily with 'legacy' partitioning information?
