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

Thanks, John.  I was afraid that was the answer. Now, II'm really
confused.  I'm guessing that the partitions will notl need to be shown
in fstab (ada0s1a).   What little mind I have left is a blank,
/dev/ad4s1g will be automatically be detected.  Is that correct?

What will I do with my second disk /dev/ad0s1a that is already zero?

I apologize but I have really confused myself.  I've filled my glass
with too much water and I'm drowning.

Thanks for everyone's patience.
