I want to install OpenSuse 11.2 with a four disk RAID-system, laid out as follows with Yast during install:
- /dev/sda1 formatted with ext2, mountpoint on /boot, 1 GB
- a raid-1 array from /dev/sda2 through /dev/sdd2, 10 GB, labeled ‘root’, mountpoint /
- a raid5 array from /dev/sda3 through /dev/sdd3, each 920 GB, net appr. 2.8 TB, labeled ‘home’, mountpoint /home
Both raid devices are mounted by label.
Partitioning and creating the arrays went without error messages, but during install of software I saw messages
Device block!9:0 not found in sysfs
flying by.
When it was time for Yast to create the initrd, the message
Kernel image: /boot/vmlinuz-2.6.31.5-0.1-desktop
Initrd image: /boot/initrd-2.6.31.5-0.1-desktop
Root device: ext4-root (/dev/block/9:0) (mounted on / as ext4)
Device block!9:0 not found in sysfs
was given, and it appeared no initrd was created:

No need to say booting this arrangement fails.
After booting the system from another disk with 11.2, and assembling and mounting the raid fs’es (with goes flawlessly), I tried to create the initrd by hand with
mount /dev/md0 /mnt/root
mount /dev/sda1 /mnt/root/boot
mount --bind /dev /mnt/root/dev
chroot /mnt/root
mount /proc
mount /sys
mkinitrd
as suggested by the mkinitrd man page. But this gives the same error, and no initrd is created in the chrooted /boot.
What am I doing wrong here?
