LinuxQuestions.org - RAID 1 on boot/root: LILO error

Hello

I'm setting up RAID 1 on my boot and root partitions, using hda and hdc

In order to be redundant, I would like to install my LILO configuration onto the MBR of both my hard drives.

My lill.conf looks like this:

Code:



lba32



# MBR to install LILO to:

#disk = /dev/md0

boot = /dev/hda #LOOK HERE

map = /boot/.map



install = /boot/boot-menu.b  

menu-scheme=Wb

prompt

delay = 50

vga = 791



#

# Linux bootable partition config begins

#

image = /boot/gentoo-2.6.11

        root = /dev/md1

        #root = /devices/discs/disc0/part3

        label = Gentoo

        read-only # read-only for checking

When boot = /dev/hda (as above), I get no errors when running /sbin/lilo. Thus, the MBR is correctly installed on /dev/hda and the computer will boot if hda is plugged in.

However, when I chagne the line and set boot = /dev/hdc, and then run /sbin/lilo, I get an error:

Code:

localhost root # lilo

Warning: /dev/hdc is not on the first disk

Warning: The boot sector and map file are on different disks.

Added Gentoo *

Added Windows

What does this mean? I know that it isn't the first disk, but that should not matter.

When I unplug hda and try and boot with just /dev/hdc plugged in, my screen is just filled with "999999999".

Any suggestions?

Cheers
