        Nothing to worry. (I got worried also when I saw it the first time)

        It is perhaps poorly worded -- multiple MD "devices" using
        same physical devices, although they are not on overlapped
        partitions, do get that message.

        It means simply that if those two were running reconstruction
        simultaneously, they would cause seeking back&forth over the
        device.
