RAID/LVM Root Filesystem on SuSE8.2

[Matthew Carpenter]

(I'm *so* sorry for the last post!  I didn't mean to hit send.  I wasn't 
done editing or describing the problems.)

Hi all,

After reading about making RAID and LVM work on your boot system (and 
foolishly misplacing the article.  Not the online one, but the one they 
didn't place online), I engaged in a little trial and error run.

I took a 30GB drive (/dev/hda) which is running my primary 
firewall/dns/dhcp for my home network, added in another 30GB drive 
(/dev/hdc) and went to town.
First off, creating two partitions on /dev/hdc setting them to partition 
type FD (auto-raid):
/dev/hdc1   128mb
/dev/hdc2   28GB

Then,  creating the md0 and md1 device (I stupidly created the md0 
device as LVM and left md1 to the /boot partition)

I then created two LV's on /dev/md0:
/dev/BigBlock/Root         (/)
/dev/BigBlock/Active       (/var - /home is a symlink to /var/home)

Copied all the data over from /dev/hda to the appropriate partition on 
/dev/md1 (/boot) and /dev/BigBlock/(Active|Root)

I then edited /boot/grub/menu.lst, adding:
title BigBlock-RAID
    root (hd0,0)
    kernel (hd0,0)/boot/vmlinuz root=/dev/BigBlock/Root console=tty1 
console=ttyS0,9600n8
    initrd (hd0,0)/boot/initrd

To be safe, I also created /etc/mdadm.conf and /etc/raidtab.  I also 
added lvm-mod and raid1 into the initrd (which were compiled as modules 
instead of into the kernel).  SuSE allows this by adding these module 
names into /etc/sysconfig/kernel and running mkinitrd.

Rebooting using this new entry kicks out the following error messages 
(many lines snipped):
