Kubuntu 9.04 on mdraid - /dev/md1 does not exist

[Mylord]

Hi all!
First time trying to install Kubuntu 9.04 alternate x64 on fakeraid (mdraid over ICH10R). Before use it only on single disk.

1. Create partitions on each of 2 HDD:

/boot - 128 Mb Primary
swap - 1 Gb Primary
/ - 10 Gb Primary
/home - 138.9 Gb Primary

2. Create raid:

raid1 md0 /boot 128 Mb ext2
raid0 md1 / 20 Gb reiserfs
raid0 md2 /home 277.8 Gb reiserfs

3. After instal and reboot i get:

/dev/md1 does not exist

I try:

mdadm -A --auto=md /dev/md0

And get:

mdadm: CREATE user root not found

mdadm: CREATE group disk not found

mdadm: no devices found for /dev/md0

Then i try:

cat /etc/fstab: no such file or directory

I try install kubuntu twice, and always get this problem. What's wrong?

Your description of steps 1 and 2 are too incomplete for us to tell what you did not do.

I create partitions, then raid with Kubuntu 9.04 x64 alternate CD. GUI, not command line.

P.S. I think, kubuntu doesn't create fstab on /boot, but why? And how i can repair this?

I have 9.04 (AMD 64 alt-install) installed on Nvidia fakeraid (ABIT NF-95 MoBo).
I just enabled RAID in the BIOS, created the array in the RAID BIOS; the installer asked if I wanted to activate the array, then I was able to partition and install directly to it.

There is at least a little confusion of technologies here. The OP is referring ro fakeraid but looking at linux based software raid (eg md) and Windy is referring to hardware, ATA, fakeraid, (probably the more common usage). also referred to as dmraid. They are entirely different.

Thanks. I know about dmraid, but i prefer mdraid as more flexible.

Apologies for the confusion, I see now you are talking about mdadm, it was the referance to mdraid that I was confusing with dmraid.
