Read the documentation in the raidtools closely especially where it
talks about the RAID autodetect.
I assume that you are using partitions as the devices for your RAID1
array. In a nutshell you use fdisk or a similar utility to set the
partition ID to fd. If you have the RAID code compiled into the
kernel the startup code will recognize these partitions and piece
together the md configuration based on the superblocks found on these
partitions. The kernel will than automatically start the devices
running.
It all works, VERY well. I have three big production servers running
with this setup and I don't hear a peep out of them.
There have been notes published lately about how to get LILO to boot
from these devices. You can study these but on all my machines I use
a separate standalone boot/root partition so that I can take a very
defensive administrative position.
