I'm working on a personal project and would like to create software
RAID-1 with GRUB on RHEL 4.1. Simple configuration: 2 physical hard
drives that I want to mirror the following partitions on:
/boot - 100MB
swap - 1024MB
/ - remainder of the drive
I can create all that while running RHEL installer using Disk Druid, but
when I reboot the system, it doesn't 'see' the boot partition and won't
boot. My research on Google indicates that GRUB has a problem booting
from software RAID....? Or that you need to set the
persistent-superblock? Unfortunately nothing I've tried worked, and I
can't get this system to boot at all.
I couldn't find any resources online that would have more detailes into
on how to go around this GRUB limitation, or how to properly set this up
using Disk Druid during RHEL installation. All documents I've seen
assume you have a bootable drive and the RAID you create is on
second/third drives. All I want is a simple system with 2 physical
drives and complete mirror (RAID-1) between the two, while keeping them
bootable. How does one make GRUB boot off a software RAID-1 /boot
partition??
Suggestions, ideas, step-by-step setup instructions or online resources
- much appreciated!

This should work. I've recently installed a new system doing exactly
this without any problems. All you should need to do is create the RAIDs
in DiskDruid, specify their mount points, and install. Can you be more
detailed about the error? "It doesn't 'see' the boot partition" tells us
almost nothing.
What type of filesystem did you use on /boot? I stick to ext2/ext3 for
this, I've never tried any other. How far through the boot process does
it get?
