I suspect that in the instructions on
https://help.ubuntu.com/community/Installation/SoftwareRAID
grub refers to grub2 because that is/was the 9.10 default for a clean
install. Anyway, grub1 doesn't do RAID.

The help should probably put the warning about RAID1 and /boot at the
very top where it says:
"How to create RAID using Ubuntu Software RAID. Including RAID 0, 1, 5 and 6."
