Hello all,
After DVD update of OpenSuSE to version 12.2, i am facing a strange
behaviour.
At the first boot, grub says to me “Unable to mount partition”. After
some work, i have sucessifully booted the system from grub command line,
with this commands:
find /boot/grub/stage1
setup (hd0,0)
kernel = /boot/vmlinuz-3.4.11-2.16-desktop
initrd = /boot/initrd-3.4.11-2.16-desktop
boot
After that, i have noticied a strange thing: the root system is mounted
from /dev/md127 (previously is /dev/md1, and yes, is a software raid).
And, more strange problem, i have tryied to reinstall grub correctly
with yast. So, i have selected Bootloader from yast (it warns me
“Because of the partitioning, the boot loader cannot be installed
properly.”), and i select “Start from Scratch”. Then, i select “Propose
New Configuration”. One configuration is the following:

Notice the Root Device empty. In the list i have:
/dev/md2
/dev/sda1
/dev/sda2
/dev/sda3
/dev/sdb1
/dev/sdb2
/dev/sdb3
tmpfs
But, the root device is /dev/md0, or i am wrong?
Anyway, i accept that config, and when tryies to install it, i have that
error:
GNU GRUB version 0.97 (640K lower / 3072K upper memory)

grub> setup --stage2=/boot/grub/stage2 --force-lba (hd0) (hd0)
Error 17: Cannot mount selected partition
grub> quit
Then if i say to Yast to not retry the bootloader configuration, i found
this on my /boot/grub/menu.lst:
default 0
timeout 8
gfxmenu

Is missing of some parts (kernel name, initrd name etc)… What’s up?
Btw, if i try to change the file /etc/grub.conf from:
setup --stage2=/boot/grub/stage2 --force-lba (hd0) (hd0)
quit
to:
setup --stage2=/boot/grub/stage2 --force-lba (hd0,0) (hd0,0)
quit
Then i manual re-install grub (grub-install), it seems to work:
GNU GRUB version 0.97 (640K lower / 3072K upper memory)

Done.
grub> quit
Now, my problem is: how i can have a working grub configuration at boot?
And, why my root is now /dev/md127?
Any help is welcome, i have now no idea to how to resolve it…
Cordially,
Claudio.
