Hi all,
I'm running an SMP (2 proc) server with 2 disks in RAID1 and GRUB under
Ubuntu Dapper 6.06, kernel 2.6.15-26-server
Raid setup is following
/dev/md0 for /boot
/dev/md1 for /
with
/dev/hd[a,c]1 is md0
/dev/hd[a,c]2 is md1
No LVM, it's working like a charm. Now I build from sources xen-3.0.2-2
kernel and install it. Grub entry is following:
title XEN, kernel 2.6.16-xen
root (hd0,0)
kernel /xen-3.0.2-2.gz dom0_mem=262144 ;have 512 MB RAM
module /vmlinuz-2.6.16-xen root=/dev/md1 ro quiet splash
module /initrd.img-2.6.16-xen
savedefault
boot
Server is booting except that I have

hdc6 is a spare partition not in a raid area. This ended in a shell on
which I'm asked to run e2fsck as superblock for /dev/md0 is corrupted or
partition is not ext2, or press CTRl/D to continue boot sequence. If I
continue, everything is ok excepted that /dev/md0 doesn't exist.
I tried to add in /lib/module/<xen version>/initrd the raid1.ko,
md-mod.ko and ext3.ko, same result.
Does anyone have an idea on what's going wrong? Thanks for any hint.
