I did use the entire underlying disk drive, as this seemed to be the way palimpsest wanted it to be done.
This was my third or fourth attempt at doing the installation and I am pretty sure I had previously tried RAID-ing the partitions, so that I ended up with /dev/md0, /dev/md1, /dev/md2, etc. but grub wouldn't install there either.

I then tried installing to a single drive, figuring I could attach the
second disk later.   After installing successfully and rebooting, I
found I had a single RAID device /dev/md3 spanning the entire disk and
it was rebuilding.   I allowed it to finish and I ended up with a
seemingly working RAID and a working grub.
