    I have been googling this for a while and couldn't find enough important
    info, but I think you finally gave me my google search term I needed:

    *transparent* nfs failover.

    Thanks, I will report any new findings, but I think I am starting to
    understand why this didn't work.  Somehow heartbeat / pacemaker setups
    have a way to overcome this, but I was merely looking for a manual
    failover to dual All-In-One boxes.
