CENTOS boot over raid partition

[Antanas Masevicius]

Hello,

this command: bootdev=`device2grub $BOOT_DEVICE` which generates an error
is not being completed thus this command:

$ROOTCMD grub --device-map=/dev/null --no-floppy --batch <<-EOF
        device $bootdev $BOOT_DEVICE

cannot be completed too, as $bootdev is not set.

This probably means that device mapping cannot be found, which is required
by grub. Not sure how this map is generated. My device.map contains only
these lines:

root at centos:~# more /boot/grub/device.map
(hd0)   /dev/disk/by-id/ata-WDC_WD5003ABYX-18WERA0_WD-WMAYP7182040
(hd1)   /dev/disk/by-id/ata-WDC_WD5003ABYX-18WERA0_WD-WMAYP7178789

device2grub is executed not via chroot /target, but from fai install with
/target mounted, thus mapping is generated not for /target but for fai
install system imho. Here are fai system modules:

mage: /boot/initrd.img-3.2.0-4-amd64: 19M
========================================================================
Version: dracut-040-207-g7252cde

Arguments: -q --force

dracut modules:
bash
dash
console-setup
network
aufs
btrfs
dm
kernel-modules
lvm
mdraid
nfs
resume
rootfs-block
terminfo
udev-rules
usrmount
base
fs-lib
shutdown
