I want to thank everyone who responded.  It is clear to me 
now what is necessary to use an ext4 filesystem.

My failure was that I was using /boot that was ext4.  I 
could select it from the grub menu on the other disk, but 
when it tried to start from there, it failed.

At least that is what I remember.  It's been a while.
