GRUB2 and software RAID1 = insmod linux

["info.emj@fr.oleane.com" <info.emj@fr.oleane.com>]

Hello list,

it's not a devel question, but seems this is a not-so-bad place to 
expose my problem. Searching with google and inside this list's archives 
didn't gave me any clue.

I want: Debian Lenny + GRUB2 + RAID1 on boot+root partition

With GRUB legacy I do:
root (hd0,0)
setup (hd0)
setup (hd1)
and everything works fine. I can boot nearly in every cases (inverted 
disks, disconnect disk, and some other weird things). Nice.

With GRUB 2 I do:
grub-install /dev/sda    # from the right /dev/md0 partition
and when I reboot I have "error: cannot find C/H/S values".
I just type "insmod linux" then "normal" then wizzzzz the system is 
loaded correctly.
I tested with GRUB_PRELOAD_MODULES="linux" in /etc/default/grub then 
update-grub but this didn't corrected the problem (obvious for me, but I 
may be wrong, so I tested).

note: I tested with GRUB2 1.96 and 1.97 from the Debian Lenny regular 
repository and backport.



My question: how can I explain to GRUB2 I don't want to type "insmod 
linux" and "normal" ?



The next step will be to install GRUB2 on both disks to allow booting 
from either one.

And my final step will be to write a small GRUB2-RAID howto nicely fited 
for GRUB2's wiki. Because hey, sparse documentation  :-)
