I was sent a good paper by John Urish in 2006 titled Software
RAID-1 and it is VERY GOOD :-)
It is complete and it tells me how to rewrite grub.conf, fstab and

Forget it. I am not this interested in RAID!
You don't need to do anything to initrd for raid-1. Since the
underlying partition is almost the same as a non-raid filesystem, you
can pretend that each /boot is a stand-alone partition as far as
booting goes. There are some tricks to make the 2nd drive boot if the
1st fails, but on IDE it's probably not worth the trouble because most
disk failure modes will hang the machine until you remove it - and at
that point you might as well swap the mirror into the 1st position,
boot the rescue CD, and reinstall grub. Still beats restoring from a
backup and losing a day's work.
The guys paper assured me that I will not boot again without all
those changes if I make my current partition fd. There is so much yes
and no about things I can't and do not want to learn by bitter experience.
I don't know what all the changes are, but you don't need a new initrd
unless you are switching to a different disk controller. You do need
grub installed on the new drive, thinking that it is booting from the
individual partition holding one of the /boot mirrors and
mounting root from the new /dev/md? device.
