    Just some more information:

    After boot, during the recovery when I add the second disk, mdadm
    --examine /dev/sdb2 shows this:

           Number Major Minor RaidDevice State
    this 0 8 18 0 active sync /dev/sdb2

        0 0 8 18 0 active sync /dev/sdb2
        1 1 0 0 1 faulty removed
        2 2 8 2 1 spare /dev/sda2

    so it appears that it thinks the second device is faulty and that I'm
    adding /dev/sda2 as a spare.
