Kernel config:
CONFIG_MD_AUTODETECT=y
build-initrd.sh config:
BOOTDEV=/dev/md1
CRYPTROOT=/dev/md2
lilo bootloader config:
boot=/dev/md1
raid-extra-boot=/dev/hda,/dev/hdd
Then use fdisk (or equivalent disk partitioning program) to set partition
type of /dev/hda2 /dev/hdd1 /dev/hda6 and /dev/hdd2 to partition type FD.
That way when linux kernel boots, it autodetects those partitions as MD
components and assembles MD RAID arrays during kernel boot. Easiest way is
let kernel autodetect and assemble all MD RAID arrays.
# fdisk -l /dev/hda | grep "hda[12]"
/dev/hda1 * 1 7 56196 fd Linux raid autodetect
/dev/hda2 8 645 5124735 fd Linux raid autodetect
# fdisk -l /dev/hdc | grep "hdc[12]"
/dev/hdc1 * 1 7 56196 fd Linux raid autodetect
/dev/hdc2 8 645 5124735 fd Linux raid autodetect
# cat /proc/mdstat | head -n 7
Personalities : [linear] [raid0] [raid1] [raid5]
