I am very confused and would appreciate some help on device renameing or on renumbering on current fstab.

Thanks, Daniel.  Your explanation makes sense to me and to eleminate
problems with ad0, it is an old disk, that I will bring up later and
just change ad4 to ada0 and ad4s1g to ada0s1g, etc. and reboot it
again early tomorrow morning about 5 am CDT and will post a working
fstab, if I manage to get it to work.

Thanks again,
