    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.

    When I install RAID with Ubuntu install after ubuntu installtions complete, after reboot have this log:
    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
    md1: active (auto-read-only) raid1 sda5[0] sdb5[1]
    4891648 blocks [2/2] [UU]
    md0: active raid1 sda1[0] sdb1[1]
    483492096 blocks [2/2] [UU]
    unused devices: <none>
    I am try
    mdadm --run /dev/md1
    mdadm --readwrite /dev/md1
    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.
