Initrd does not contain /dev/sda1 (so does not boot)

alaios · 01-14-2013, 03:03 PM

Hi everyone,
after upgrading from opensuse 11.2 to 12.1 my system can not boot. Actually it fails to boot at the very first stages (grub has something like root=/dev/sda3 but the device is never found). I have tried a bit and I think I gathered important debugging information.

the grub/menu.lst

Code:

# Modified by YaST2. Last modification on Mon Jan 14 17:49:18 CET 2013
# THIS FILE WILL BE PARTIALLY OVERWRITTEN by perl-Bootloader
# For the new kernel it try to figure out old parameters. In case we are not able to recognize it (e.g. change of flavor or strange install order ) it it use as fallback installation parameters from /etc/sysconfig/bootloader

default 2
timeout 8

I also followed the instructions, provided on first page to unpack the initrd

Code:

zcat /media/boot/initrd-3.4.11-2.16-desktop | cpio -imduv

Inside initrd's etc/ there is no file called
mdadm.conf

and dev/ is empty (probably this explains a lot)

What else might be needed? Hm...
my /grub/device.map looks like that

Code:

(fd0)   /dev/fd0
(hd0)   /dev/disk/by-id/ata-WDC_WD20EVDS-63T3B0_WD-WCAVY6660374

What should I do now? How to make opensuse boot again?

What are your partition layout? If you don't know boot to a live-CD and launch, as root, the command

Code:

fdisk -l

yancek · 01-14-2013, 04:59 PM

You menu.lst file has "root (hd0,1) which would be sda2 in Grub Legacy and your kernel line has "root=/dev/sda3". More info suggested above would help.

Indeed you are right. Please find the full "collection" and description

at grub I receive the following messages (as system is down and could not copy paste please find screnhots)before booting halts.

What else do you think might be needed to fix that ?

It seems that your initrd is corrupt, it is even missing commands. I don't know which command it is on openSuse (maybe it is even possible with Yast), but all distros have a command to rebuilt the initrd.
I would recommend to try that.
