Gmirror dump device does not exist?

  I have just set up a FBSD6.0 server configured with gmirror/raid1
using two SATA drives ad4 & ad6 according to these instructions:


  Everything is functioning properly with the exception of a boot
warning that indicates that a dump device does not exist.  I'm sure
that I just missed something simple during the setup procedure.  Does
anyone have the quick fix for this?

My fstab:
