Can't boot from /dev/md0 (RAID-1)

Can't boot from /dev/md0 (RAID-1)

[Roy Sigurd Karlsbakk]

I hope this is not OT - didn't find any LILO mailing list. after trying 
virtually everything - can anyone help me with a tip?


Running 2.4.19-pre10-ac2, RedHat 7.3 (LILO version 21.4-4), I have root on 
/dev/md0 on RAID-1 on /dev/hda1 and /dev/hdb1. I've tried the howto at 
http://www.tldp.org/HOWTO/mini/Boot+Root+Raid+LILO-3.html#ss3.1, but it still 
doesn't help me. lilo just tells me "L 99 99 99 99 ..." some half a page, and 
then stops.I'm trying. All the time it prints this, it seems to be searching 
the floppy for some reason.


The lilo.conf suggested by the above HOWTO, is this


# lilo.conf.hda - primary ide master
disk=/dev/md0
bios=0x80
sectors=63
heads=16
cylinders=39770
partition=/dev/md1
start=63
boot=/dev/hda
map=/boot/map
install=/boot/boot.b


image=/boot/bzImage
        root=/dev/md0
        read-only
        label=LinuxRaid


sector/head/cylinder is corrected to the actual data reported from 'fdisk 
-ul'. 


When trying to set. boot=/dev/hdm (which is the first drive on the on-board 
chipset), lilo installs, and I get LI instead of L 99 99 ... Same result with 
LBA32.


I also have another box with Linux, running SuSE 7.2 (LILO version 21.7-5) 
with RAID-1 on two drives. Here everything works fine


thanks for all help

please someone update that blasted howto, lilo has been supporting boot from md
for ages.

use:
boot=/dev/md0
map=/boot/map
install=/boot/boot.b

image=/boot/bzImage
    root=/dev/md0
    read-only
    label=LinuxRaid

This has been in the Software-RAID HOWTO since january 2000.

This is indeed the correct way to do things.

Actually, on a Debian box I set up recently I needed to do the
following:

  boot=/dev/md0
  raid-extra-boot=/dev/sda,/dev/sdb

This tells LILO exactly where to write the MBRs - this is not usually
needed though.

I've read the fscking manual - all I can find - for both grub and lilo, and 
I've tried all possible configurations I can think of.

point is - I beleive there's a BIOS/linux misunderstanding somewhere

Did you try the   raid-extra-boot  option for LILO ?  I really don't
know if this is the problem you are seeing, but it's worth a shot I
think.
