    When a member of a RAIDZ has been replaced with a device smaller than the
    original, then the top level vdev can report its expand size as 16.0E.
    The reduced child asize causes the RAIDZ to have a vdev_asize lower than its
    vdev_max_asize which then results in an underflow during the calculation of the
    parents expand size.
    Also for RAIDZ vdevs the sum of their child vdev_min_asize could be smaller
    than the parents vdev_min_size.
