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

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

[Roy Sigurd Karlsbakk]

hi

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

Hi,
I had this once and resolved it with adding a "default" line to the
lilo.conf:
default = LinuxRaid

Also have boot=/dev/md0, not boot=/dev/hda.

Cheers,
Juri

hm

I keep getting this one..

[root@jumbo root]# lilo
boot = /dev/hda, map = /boot/map.0301
Added linux2419rc1 *
Added linux2418
Added linux-orig
Fatal: Duplicate geometry definition for /dev/md0

Any ideas?

Hm, I'm no lilo nor raid expert, but I'd suggest to strip down the
lilo.conf to the defaults. E.g. I have:
prompt
timeout=50
default=linux
boot=/dev/md2
map=/boot/map
install=/boot/boot.b
message=/boot/message

image=/boot/vmlinuz
        label=linux
        read-only
        root=/dev/md0

hm...
still gave me 'LI'
I beleive it might be because LILO need to be installed on the first drive 
BIOS finds (/dev/hdm). I might try to address it as 0x80? Do you think 
that'll help?

I assume the onboard IDE stuff (hdm) is something like a Promise
controller. If so you should be able set the boot order to boot from the
normal IDE chipset (hda/hdb). If doesn't help I'd suggest that you ask
on the linux-raid mailing list.

The on-board is a VIA controller. see from lspci

00:0c.0 Unknown mass storage controller: Promise Technology, Inc. 20268 (rev 
02)
00:0d.0 Unknown mass storage controller: Promise Technology, Inc. 20268 (rev 
02)
00:0e.0 RAID bus controller: CMD Technology Inc PCI0649 (rev 02)
00:11.1 IDE interface: VIA Technologies, Inc. Bus Master IDE (rev 06)

and - as for linux-raid, see below:

   ----- The following addresses had permanent fatal errors -----

    (reason: 550 5.1.1 <linux-raid@vger.rutgers.edu>... User unknown)

So you have your two raid drives connected to the VIA controller, right?
Then have a look into the BIOS setup and see, if there's something that
might affect the boot order...

No wonder, vger.rutgers.edu ceased to exist ~2 years ago. Use
vger.kernel.org instead ;)

I have 4 drives connected to each controller, that is, 2 drives per channel. 
None are RAID controllers - just stupid ATA controllers. 

point isn't to change bootorder - just to make bloody LILO work.

See fstab, jumbo-dmesg.txt, mdstat and raidtab in http://karlsbakk.net/bugs/ 
for more info

It doesn't work. Still LI only.

Any other ideas

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

[dean gaudet]

my system has 4 disks, but /dev/md0 is a RAID1 for /boot.  (/dev/md1 is a
RAID5 and LVM is on top of it...)  anyhow, this is what works for me.
i've even pulled out a disk and it still boots.

btw, you really don't want to put two drives on an IDE controller.  not
just for performance reasons -- if a master drive fails it can easily
prevent access to the slave... so you'll have a two disk failure on your
hands.  or maybe this is just urban legend and i'm spreading it further ;)

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.

hi

trying this:
--
boot=/dev/md0
map=/boot/map
install=/boot/boot.b.hda
backup=/boot/boot.b.rs.hda
prompt
timeout=50
lba32
raid-extra-boot=/dev/hda,/dev/hdb
...

with lilo-21.4-4 (standard with rh73) it won't accept the raid-extra-boot 
option

and

with lilo-22.3.1, it won't accept (i beleive boot=/dev/md0)

[root@jumbo lilo-22.3.1]# lilo
Warning: using BIOS device code 0x80 for RAID boot blocks

Ok - I use it with LILO 22.2 here, it's on Debian, and it's the only box
where I ever needed that option.

My lilo.conf:
----------8<--------
lba32
boot=/dev/md0
raid-extra-boot=/dev/sda,/dev/sdb
root=/dev/md1

disk=/dev/sda
 bios=0x80
disk=/dev/sdb
 bios=0x81

install=/boot/boot-menu.b

delay=20
default=Linux

image=/boot/vmlinuz
  label=Linux
  read-only
----------8<--------

The following is from a standard RedHat 7.3 system with LILO 21.4.4-14:

----------8<-----8<-----
boot=/dev/md3
map=/boot/map
install=/boot/boot.b
message=/boot/message
prompt
timeout=40
linear
default=2.4.18
image=/boot/vmlinuz-2.4.18
  label=2.4.18
  read-only
  root=/dev/md2
----------8<-----8<-----

Both systems are SCSI-only though.

The following is an IDE-only RedHat 7.2 with LILO 21.4.4.14

----8<-----8<------------
boot=/dev/md0
map=/boot/map
install=/boot/boot.b
prompt
timeout=50
message=/boot/message
linear
default=linux
image=/boot/vmlinuz
  label=linux
  read-only
  root=/dev/md1
----8<-----8<------------

Perhaps you could change the lba32 option into linear ?  I'm really
shooting in the mist here - LILO tends to "just work", and ignorance is
bliss   ;)

It still won't work. It doesn't seem to like boot=/dev/md0. see below

What buffles me is that - according to your dmesg output at
http://karlsbakk.net/bugs/dmesg - the disk connected to the onboard VIA
controller are detected as hdm-hdp.
Have you checked you BIOS settings? Some mainboards allow to use
off-board controllers to be used before the on-board ones...
