software raid1 problems, please help

Hello people

i`m willing to install software raid1 on my home server (archlinux 2.6.30)
i have 2 8.4GB hdds /dev/sda && /dev/sdb

i configuret partitions following wiki & some other tutorials, but so far i`m unsuccessfull

heres what i did

partitioned bouth drives (a & b) identicaly

100mb boot
512mb swap
7800mb /

made raid1 array

mkfs.ext2 boot and / partitions
mkswap /dev/md2 (swap partiton)

when i wrote fdisk -l it showd this
Disk /dev/mdX doesn't contain a valid partition table
wher X is 1,2,3

i have added dm-mod in rc.conf mkinitcpio.conf but nuthing works

when i try to boot sistem it says this

::Running Hook [raid]
md: raid1 personality registred for level 1
waiting 10 seconds for device /dev/md3 ...

root device '/dev/md3' doesn't exist, attempting to create it
ERROR: Failed to parse block device ids for '/dev/md3'
ERROR: Unable to detect or create root device '/dev/md3'
You are being dropped to a recovery shell
type reboot to reboot
type exit to continue

when i type exit, it starts to panic...

ont thing i`m woried about is that, when i partition my drives and enter setup, i should skip partition part, but when i want to select packages it says that my drives are not partitioned - is this how it should be ?

Please help me, i realy need to get this working.

allso i`m wondering what jumper settings should i use on bouth drives?
i have read that puting /boot partition in raid couses problems, is that true ? because i have /boot in raid1 allso..

my best regards
karlis.

Re: software raid1 problems, please help

well i think i have blown up something.. i updated glibc and system died permanently.. so i reinstaled it, put same settings back in mkinitcpio.conf mdadm.conf menu.lst fstab but system does not boot up.. says thesame about that cannot find device /dev/md3 wich is root partition..

i`m wonderig is this something to do with jumpers on hdd's ?
