FC14 problem "no root device found"

Hello List,

I tried replacing my existing system with a raid-5/lvm setup by I ran 
into some trouble mounting the root partition during the boot sequence.

I created a raid-1 device for the /boot partition. I copied my existing 
boot to /boot and my existing root to the LVM-volume that is ontop of a 
raid-5 device. I tried booting from it, but I just can't get it to mount 
the root right after it boots the kernel. I get the message "no root 
device found".

I pretty much tried everything. I recreated the initrd because I thought 
it might have something to do with the raid device (which I didn't have 
before). But after inspecting the initrd contents of my original stock 
kernel, I found mdadm and other raid-related files. So I figured that 
shouldn't be the problem.

I tried specifying the root partition in a number of ways. By UUID, by 
"/dev/mapper/raid--5--lvm-root", by "/dev/md-0", by "/dev/raid-5/root", 
by label "root". Nothing worked.

Does anyone have any idea how to solve this?

Kind Regards,
