Default Problem with RAID 1

Hello!

I have problem to create RAID 1 when I install Ubuntu 10.04 64 bit.
I have two HDD WD Black 500GB SATA2.
I created two partitions on one HDD and the same on second HDD, all with bootable flag and / and so on.

After instalation I have inif terminal!

Where is a problem?

MB Intel S3420GPV

P.S. In hdd list I see SCSI1 (0,0,0) and SCSI2 (0,0,0)? It is normal?
DVD-ROM SATA too.

Big thnks.

Now I am try to create RAID 1 from this post http://http://howtoforge.com/how-to-...buntu-10.04-p3

But after restart have this log:

Code:
Common problems:
- Boot args (cat /proc/cmdline)
-Check rootdelay= 
-Check root=
- Missing modules (cat /proc/modules; ls /dev)
ALERT! /dev/md0 does not exist. Dropping to a shell!
And now have initramfs terminal.

What I can to do now to decide this problem?

Big thnks.

When I install RAID with Ubuntu install after ubuntu installtions complete, after reboot have this log:
Code:
mount: mounting /dev/disk/by-uuid/dd6c807e-4433333 on /root
failed: Invalid argument
mount: mounting /dev on /root/dev failed: No such file or dir
mount: mounting /sys on /root/sys failed: No such file or dir
mount: mounting /proc on /root/proc failed: No such file or dir
Target filesystem doesnot have /sbin/init.
No init found. Try passing init= bootarg.
May be my motherboard not support Ubuntu Software RAID???

I try ti install Debian.
After instalation all seems ok, but in cat /proc/mdstat
Code:
md1: active (auto-read-only) raid1 sda5[0] sdb5[1]
4891648 blocks [2/2] [UU]
resync=PENDING

md0: active raid1 sda1[0] sdb1[1]
483492096 blocks [2/2] [UU]

unused devices: <none>
I am try
mdadm --run /dev/md1
and
mdadm --readwrite /dev/md1
but
mdadm: failed to set writable for /dev/md1: Device or resource busy

How I can to decide this problem, or it is not a problem for swap partition?

Big thnks!

Problem is decided.

Problem was in partition installerin Ubuntu 10.04.
You need to create partitions and save over ~100MB as free space.
Or firstly create partions with Gpart and after that install the system.
