boot fails after pacman -Syu

go4it · 2006-10-04 11:06:46

Hi, I did pacman -Syu and after this the system did not boot anymore.
I noticed 2.6.18 kernel files

First I got problem with master boot block
then I got: Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)

- As proposed in another topics I tried already:

in /etc/fstab

/dev/discs/disc1/part3 / ext3 defaults 0 1
/dev/discs/disc1/part1 /boot ext2 defaults 0 1
/dev/discs/disc1/part2 swap swap defaults 0 0

changed to

/dev/hdd3 / ext3 defaults 0 1
/dev/hdd1 /boot ext2 defaults 0 1
/dev/hdd2 swap swap defaults 0 0

in /boot/grub/menu.lst

# (0) Arch Linux
title Arch Linux [/boot/vmlinuz26]
root (hd1,0)
kernel /vmlinuz26 root=/dev/discs/disc1/part3 ro

changed to

# (0) Arch Linux
title Arch Linux [/boot/vmlinuz26]
root (hd1,0)
kernel /vmlinuz26 root=/dev/hdd3 ro
initrd /boot/kernel26.img

and now I got:

Booting 'Arch Linux [/boot/vmlinuz26]'

root (hd1,0)
Filesystem type is ext2fs, partition type 0x83
kernel /vmlinuz26 root=/dev/hdd3 ro
[Linux-bzImage, setup=0x1400, size=0x2917b71]
initrd /boot/kernel26.img

Error 15: File not found

=============================

- I tried first to change disks/disk1/part3 to change to hdb3 but this failed. then I noticed that a Live boot disk mounted hdd1 hdd2 and hdd3

My bios configuration:

primary IDE controller CD-1
CD-2
secondary IDE controller hd-0 Win
hd-1 Arch

and now I get lost....thanks

Have you tried dev/hda[1-3]? Maybe it's only the live boot disk that mounts to hdd and Arch is looking for hda...

no, as I read in another topic

disks/discO/part3 > hda3
disks/disc1/part3 > hdb3

I tried initially only hdb[1-3]

Mr Green · 2006-10-04 12:10:24

kernel /vmlinuz26 root=/dev/hdd3 ro

try adding /boot ..... to kernel line....

go in grub press e

go4it · 2006-10-04 14:55:33

Mr Green, thanks for your advise

Before adding /boot

root (hd1,0)
Filesystem type is ext2fs, partition type 0x83
kernel /vmlinuz26 root=/dev/hdd3 ro
[Linux-bzImage, setup=0x1400, size=0x2917b71]
initrd /boot/kernel26.img

Error 15: File not found

=========

After

root (hd1,0)
Filesystem type is ext2fs, partition type 0x83
kernel /boot/vmlinuz26 root=/dev/hdd3 ro

Error 15: File not found

==============

So I removed the line: initrd /boot/kernel26.img

and have this set back:

kernel /vmlinuz26 root=/dev/hdd3 ro

and reboot
result:

Checking filesystem Fsck.ext3: No such file or directory while trying to open /dev/hdd3 .....

Mr Green · 2006-10-04 15:18:25

errr you need initrd line or else its not going to work at all

I asked you to add boot becuase I assume you have a separate /boot partition

Don't use grub here so cannot be certain of your drive set up....

root (hd1,0)
kernel /boot/vmlinuz26 root=/dev/hdd3 ro
initrd /boot/kernel26.img

Hi sigi,

I tried it

kernel /vmlinuz26 root=/dev/hdd3 ro changed to
kernel /vmlinuz26 root=/dev/hda3 ro

and then I got:

VFS: Cannot open root device "hda3" or unknown-block(0,0)
Please append a correct "root=" boot option
Kernal panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)

gradgrind · 2006-10-04 15:30:07

Er, if you had ....disc1.... (=hdb) and it worked, why is everyone going on about hdd? (=disc4)

Mr Green · 2006-10-04 15:41:16

I just copied what he had in his menu.lst I have no idea what drive he has arch on...

Cerebral · 2006-10-04 15:48:12

disc1/part[1-9] should normally become hdb[1-9]

Try these:

/etc/fstab

/dev/hdb3 / ext3 defaults 0 1
/dev/hdb1 /boot ext2 defaults 0 1
/dev/hdb2 swap swap defaults 0 0

/boot/grub/menu.lst

# (0) Arch Linux
title Arch Linux [/vmlinuz26]
root (hd1,0)
kernel /vmlinuz26 root=/dev/hdb3 ro
initrd /kernel26.img

And see how that works. (Note: your initrd image will be in the same directory as your kernel - hence no /boot in front)

Mr Green · 2006-10-04 15:54:54

where did he get hdd from ?...

I see hd(1,0) is hdb ... so of course he does not need /boot

use lilo much easier lol

go4it · 2006-10-04 16:58:13

double post

Mr Green · 2006-10-04 17:04:43

Can you tell how you installed Arch ?

What iso you are using ?

It may help us

go4it · 2006-10-04 17:04:47

Hi Cerebral,

starting from a live CD I found vmlinuz26 Jan 2005 2698679 bytes in
/mnt/hdd1 but not initrd
I did not find kernel26.img ! Does this mean it was not downloaded by pacman ?

changed back to hdb[1-3] in fstab and menu.lst just as you proposed.
- this is the error:

Booting 'Arch Linux [/boot/vmlinuz26]'
root (hd1,0)
Filesystem type is ext2fs, partition type 0x83
kernel /vmlinuz26 root=/dev/hdb3 ro

initrd /boot/kernel26.img

Error 15: File not found

I installed Arch linux a year ago from an iso download.
When the system started it said version Archlinux 7.0 while booting

but as I told you already

The disk were I installed Archlinux is on the slave disk on the secondary IDE
I did not changed the hardware after upgrading, so the previous Arch ran well on this hardware.

Mr Green · 2006-10-04 17:25:41

Well I'm running 0.7.2 here ...

Not sure what to say other than you may need to chroot in & pacman -Syu again

watch any output

pacman -S kernel26 make sure mkinitcpio runs .. (look in boot for kernel26.img)

Rescue_a_system_with_a_broken_boot_loader may help you

You've still got the /boot in there, remove it!

initrd /kernel26.img

solved or not solved? :oops:

go4it · 2006-10-04 21:59:07

Not yet solved !

Based on this [url] http://wiki.archlinux.org/index.php/Mkinitcpio#GRUB link [/url]
I understand that one can have either a separate boot partition or not.
I have.

What I found:

vmlinuz26 is is in hdb1 which is my boot partition
kernel26.img is in hdb3/boot

that is why I got a "file not found" for kernel26.img only.

Now I copied kernel26.img to hdb1 and now the boot process does not
gives "file not found" but I got stuck in another error message:

ERROR: failed to parse block device name for '/dev/hdb3' unknown
ERROR: root fs cannot be detected try using the rootfstype= kernel parameter.
::Initramfs completed - control passing to kinit
md: Autodetecting RAID arrays
md: autorun ...
md: .. autorun DONE.
Kernel panic - not syncing: Attempted to kill init !
 -

I am gooing to sleep now ( midnight here)
Many thanks to everybody to help me !

gradgrind · 2006-10-05 04:32:26

Try using initrd /kernel26-fallback.img (remember to copy it to hdb1 if it is not there!). It sounds like your kernel26.img might be incorrectly built.

Hi grandgrind

I have the same error message, the files are found, a lot of information dump on my screen and than the sync problem.

what does this mean ?

ERROR: failed to parse block device name for '/dev/hdb3' unknown

and now I got:

this error is gone
Kernel panic - not syncing: Attempted to kill init !
and continues with:

FATAL: Could not load /lib/modules/2.6.10-ARCH/modules.dep: No such file or directory

shouldn't it be 2.6.18 ?

So it seems that CD on the primary IDE and disks on the Secondary IDE
seems to be a problem for upgrading from v0.7.0 to v0.7.2

Shouldn't I swap the IDE flatcables ?
If I should do this is the kernel26.img right for this new hw configuration ?
