Installing Mandriva with Software RAID

Recommended Posts

I'm currently using Mandriva 2008.1 with a RAID1+LVM. Here is how I'm setup:

#fdisk -l /dev/hda /dev/hdc
Disk /dev/hda: 122.9 GB, 122942324736 bytes
16 heads, 63 sectors/track, 238216 cylinders
Units = cylinders of 1008 * 512 = 516096 bytes
Disk identifier: 0x1fd11c08

  Device Boot      Start         End      Blocks   Id  System
/dev/hda1   *           1         130       65488+  fd  Linux raid autodetect
/dev/hda2             131      152510    76799520   fd  Linux raid autodetect
/dev/hda3          152511      154541     1023624   82  Linux swap / Solaris

Disk /dev/hdc: 122.9 GB, 122942324736 bytes
16 heads, 63 sectors/track, 238216 cylinders
Units = cylinders of 1008 * 512 = 516096 bytes
Disk identifier: 0x15f5dc62

  Device Boot      Start         End      Blocks   Id  System
/dev/hdc1   *           1         130       65488+  fd  Linux raid autodetect
/dev/hdc2             131      152510    76799520   fd  Linux raid autodetect
/dev/hdc3          152511      154541     1023624   82  Linux swap / Solaris

# cat lilo.conf (edited for top only)
default="linux"
boot=/dev/md0
map=/boot/map
install=menu
keytable=/boot/us.klt
raid-extra-boot=mbr
menu-scheme=wb:bw:wb:bw
compact
prompt
nowarn
timeout=20
message=/boot/message

 

Note that raid-extra-boot is set to 'mbr' and NOT the drives. Somehow this knows to write to the boot sectors of your boot device. /dev/hda1 and /dev/hdc1 are the md0 members and md0 is an ext3 partition that is only big enough to put the "/boot" directory in. I had in the past tried to make the boot partition xfs but raid had issues with it. This method is may not be necessary in Mandriva 2009.

 

Hope that helps.

I don't know about Mandriva, but my system has no problem with RAID booting XFS.

 

And here's my lilo.conf. Tell me what I have wrong here.

 

 

# LILO configuration file

# generated by 'liloconfig'

#

# Start LILO global section

# Append any additional kernel parameters:

append=" vt.default_utf8=0"

boot = /dev/md0

raid-extra-boot=mbr-only

lba32

compact

fix-table

large-memory

 

# Boot BMP Image.

# Bitmap in BMP format: 1024x768x16M

bitmap = /boot/slack.bmp

# bitmap = /boot/charisma_lowres.bmp

# Menu colors (foreground, background, shadow, highlighted

# foreground, highlighted background, highlighted shadow):

bmp-colors = 255,0,255,0,255,0

# Location of the option table: location x, location y, number of

# columns, lines per column (max 15), "spill" (this is how many

# entries must be in the first column before the next begins to

# be used. We don't specify it here, as there's just one column.

# bmp-table = 60,6,1,16

# Timer location x, timer location y, foreground color,

# background color, shadow color.

bmp-timer = 65,27,0,255

 

# Standard menu.

# Or, you can comment out the bitmap menu above and

# use a boot message with the standard menu:

#message = /boot/boot_message.txt

 

# Wait until the timeout to boot (if commented out, boot the

# first entry immediately):

prompt

# Timeout before the first entry boots.

# This is given in tenths of a second, so 600 for every minute:

timeout = 100

# Override dangerous defaults that rewrite the partition table:

change-rules

reset

# VESA framebuffer console @ 1280x1024x64k

vga = 794

# End LILO global section

#

# Linux bootable partition config begins

# This has been modified for RAID boot devices.

#

# This is from: fdisk -l

# 255 heads, 63 sectors/track, 121601 cylinders

# Units = cylinders of 16065 * 512 = 8225280 bytes

# lilo.conf.sda - primary sata master

# Disk identifier: 0x3da7c347

disk=/dev/sda

bios=0x80

sectors=63

heads=255

cylinders=16065

partition=/dev/md1

start=63

# boot=/dev/sda # this is the first disk

# raid-extra-boot=mbr

# lilo.conf.sdb - secondary sata master

# Disk identifier: 0x2def0710

bios=0x80

start=63

# boot=/dev/sdb # this is the second disk

# raid-extra-boot=mbr

# ------------------------- #

# ------------------------- #

# lilo.conf.sda - primary sata master

# Disk identifier: 0x3da7c347

# disk=/dev/md0

bios=0x80

sectors=63

heads=255

cylinders=16065

partition=/dev/md1

start=63

# boot=/dev/sda # this is the first disk

# raid-extra-boot=mbr

install=/boot/boot.b

image = /boot/vmlinuz-stable

# ---------------------

 

# lilo.conf.sdb - secondary sata master

# Disk identifier: 0x2def0710

# disk=/dev/md0

bios=0x80

sectors=63

heads=255

cylinders=16065

partition=/dev/md1

start=63

# boot=/dev/sdb # this is the second disk

# raid-extra-boot=mbr

map=/boot/map

install=/boot/boot.b

image = /boot/vmlinuz-stable

root=/dev/md0

read-only

label = BEssentialBEing

 

# Linux bootable partition config ends

# ---------------------

 

I get this error from running lilo:

 

Added BEssentialBEing *

Syntax error at or above line 75 in file '/etc/lilo.conf'

 

It never adds the second system.
