    There might be a chicken-and-egg problem here.  Be sure to back-up the
    data on the partition before proceeding (if its important).  Then
    try doing a raw-mode update:

    disklabel -r -w -B /dev/ad1s1

    That only works if there is already a disklabel on that partition.  If
    there isn't you have to install a label first, or as part of the
    command:


    *** WARNING, THIS WILL DESTROY ALL DATA IN THE PARTITION ***

    disklabel -r -w -B /dev/ad1s1 auto
