 Posted: Wed Jun 02, 2004 11:41 am Post subject: sata boot problems using iswraid |
 |
|
I am running two sata drives in software raid. After compiling the kernel and trying to boot, it hans up at trying to mount the root device.
The error says Root block device is unspecified or not detected.
I compiled the kernel with the iswraid patch and the libata patch.
my lilo.conf looks like:
| Code: | $Header: /home/cvsroot/gentoo-x86/sys-boot/lilo/files/lilo.conf,v 1.1 2003/1$
# Author: Ultanium
# Start LILO global section
# Faster, but won't work on all systems:
compact
# Should work for most systems, and do not have the sector limit:
lba32
# If lba32 do not work, use linear:
#linear
# MBR to install LILO to:
boot = /dev/ataraid/d0
map = /boot/.map
disk=/dev/sda
inaccessible
disk=/dev/sdb
inaccessible
# If you are having problems booting from a hardware raid-array
# or have a unusual setup, try this:
#disk=/dev/ataraid/d0 bios=0x80 # see this as the first BIOS disk
#disk=/dev/sda bios=0x81 # see this as the second BIOS disk
#disk=/dev/hda bios=0x82 # see this as the third BIOS disk
# Here you can select the secondary loader to install. A few
# examples is:
# boot-text.b
# boot-menu.b
# boot-bmp.b
install = /boot/boot-menu.b # Note that for lilo-22.5.5 or later you
# do not need boot-{text,menu,bmp}.b in
# /boot, as they are linked into the lilo
# binary.
menu-scheme=Wb
prompt
# If you always want to see the prompt with a 15 second timeout:
timeout=150
delay = 50
# Normal VGA console
#vga = normal
# VESA console with size 1024x768x16:
vga = 0x317
# End LILO global section
# Linux bootable partition config begins
image = /boot/kernel-2.4.25-gentoo-r3
root = /dev/ram0
ramdisk=8192
#root = /devices/discs/disc0/part3
label = Gentoo
append="init=/linuxrc"
read-only # read-only for checking
initrd=/boot/initrd-2.4.25-gentoo-r3
# Linux bootable partition config ends
# DOS bootable partition config begins
other = /dev/ataraid/d0p1
#other = /devices/discs/disc0/part1
label = Windows
# DOS bootable partition config ends
|
my fstab looks like:
| Code: |
# /etc/fstab: static file system information.
# $Header: /home/cvsroot/gentoo-src/rc-scripts/etc/fstab,v 1.14 2003/10/13 20:03:38 azarah Exp $
#
# noatime turns off atimes for increased performance (atimes normally aren't
# needed; notail increases performance of ReiserFS (at the expense of storage
# efficiency). It's safe to drop the noatime options if you want and to
# switch between notail and tail freely.
# <fs> <mountpoint> <type> <opts> <dump/pass>
# NOTE: If your BOOT partition is ReiserFS, add the notail option to opts.
/dev/ataraid/disk0/part2 /boot ext2 noauto,noatime 1 1
/dev/ataraid/disk0/part4 / reiserfs noatime 0 0
/dev/ataraid/disk0/part3 none swap sw 0 0
/dev/cdroms/cdrom0 /mnt/dvd auto noauto,ro 0 0
/dev/cdroms/cdrom1 /mnt/cdr auto noauto,ro 0 0
/dev/fd0 /mnt/floppy auto noauto 0 0
# NOTE: The next line is critical for boot!
none /proc proc defaults 0 0
# glibc 2.2 and above expects tmpfs to be mounted at /dev/shm for
# POSIX shared memory (shm_open, shm_unlink).
# (tmpfs is a dynamically expandable/shrinkable ramdisk, and will
# use almost no memory if not populated with files)
# Adding the following line to /etc/fstab should take care of this:
none /dev/shm tmpfs defaults 0 0
none /dev devfs defaults 0 0
none /sys sysfs defaults 0 0

any help would be appreciated

i've tried ataraid before. its buggy. firstly, make sure which device is what. on my last system, /dev/ataraid/disc0/disc got mapped to /dev/hde, but i couldn't write to hde's MBR becasue lilo wouldn't let me, and i couldn't write that the drive wasn't /dev/ataraid/disc0/disc on that device either. every time i booted it said /dev/ataraid/disc0/disc wasn't there. then i would type in /dev/hde and all would be fine.
in fstab are you sure it is "disk" and not "disc"?
did you do:
mkdir /mnt/gentoo/dev
mout -o bind /dev /mnt/gentoo/dev |

It looks like the initrd is not loading the iswraid, i am using genkernel to compile.
Writing to the MBR is no problem, I just can't get to a regular boot.
Is there any way to edit the initrd to include iswraid.o? |

Why not build a new one. I've seen posts on the forum that detail how to go about that. This is one I think:

I just finished building today and the module now loads up.
I now get an error that says
| Quote: | | iswraid: probed 0 scsi disks, found 0 iswraid disks |
I know I have iswraid because that is waht loads on the bootable cd.
I think it said something about changing the parameters at boot.
If anyone could help, I would appreciate it

After talking to the driver creator for quite some time i have got the raid detected by iswraid then immediately the system hangs after giving me.

I have no idea what all this means. After cruising around the forum and the internet, the guilty part could either be devfs or the reiserfs not talking to the ataraid.
If somebody could point me in the right direction i'd appreciate it.

more than likely this is cause by the iswraid function being called before the scsi part of the kernel which detects the disk, if these are in initrd you may need to order it so the scsi-disk module is loaded first. (so the disks are initialised for iswraid to detect them) |

looks like a problem with devfs  |

The trick is to not enable the high mem support in the kernel. It conflicts with the iswraid driver.

| if you disable high mem then you wont be able to take advantage of ram more than 1 gb ? im assuming im a noob with a lot of this kernel stuff |

I got the information directly from the guy that work at intel who wrote the iswraid support for the intel ataraid subdriver. He said he would correct this on the next release of the driver and it was only a temporary hicup.
