lilo / raid1 / mbr problem

[Dirk Bonenkamp - Bean IT <dirk@bean-it.nl>]

Hi All,

Running debian testing/unstable with 2.6.9

I wanted to reconfigure a server so that it used a raid 1 array instead of 
just one disk.

This is what I did:

Reconfigured the system so that it boots from /dev/hdc

Created a raid 1 array (/dev/md0) on /dev/hda (/dev/hda1, just one raid 
partition plus one swap partition). Marked the second disk as 'missing'. 
The idea is to add this drive to the array once the OS is transferred to 
the raid array.

Created a reiserfs filesystem on /dev/md0.

Mounted /dev/md0 under /mnt and copied the running OS to /dev/md0.

Changed /mnt/etc/lilo.conf:

lba32
boot=/dev/md0
raid-extra-boot=mbr
root=/dev/md0
install=/boot/boot-menu.b
map=/boot/map
message=/boot/bootmess.txt
        prompt
        #single-key
        delay=100
        timeout=100

vga=normal

default=2.6.9

image=/boot/vmlinuz-2.6.9
        label=2.6.9
        read-only

Then, when I try:

lilo -r /mnt

I get:

Warning: Int 0x13 function 8 and function 0x48 return different
head/sector geometries for BIOS drive 0x81
Fatal: Unable to open mb

I've googled around, but I can't find an answer. I've did this 'changing to 
raid' thing serveral times, all went OK. I've checked the disk, replaced 
the disk... I'm out of clues... Any hint or help would be very appreciated!

TIA,

Dirk
