    How can I set RAID 0 using Ubuntu Server 12.04

    I have a server which installed 2 HDD (500 GB each).

    I would like to install Ubuntu Server 12.04 on it but when I partition my disks like :

    "Configure software RAID" > YES > "Create MD device" > RAID0 > and check both "/dev/sda1" and "/dev/sdb1"
    > continue > Finish. Now I got
    RAID0 device #0 - 1.0TB Software RAID device
    #1 1.0 TB
    512.0 B unusale
    SCSI1 (0,0,0) (sda) - 500.1 GB ATA MB0500EBNCR
    #1 primary 500.1 GB K raid
    SCSI1 (0,0,0) (sdb) - 500.1 GB ATA MB0500EBZQA
    #1 primary 500.1 GB K raid
    then I select "Finish partitioning and write changes to disk".

    After that, I got an error message
    No root file system
    No root file system is defined.
    Please correct this from the partitioning menu
    Could you please tell me, how can I solve this problem?

    Thank you for every answer.

    PS. This Machine will be used as File Server

    Hello & welcome!

    I don't know if it is still necessary, but at least at one time, an "alternate" Ubuntu CD/DVD was required for installing Ubuntu in RAID 0. During the partitioning stage of the installer, are you using the manual installer, I assume?

    See the below video tutorial for a bunch of details on that process, maybe there will be a pointer there. I watched all of Part 1 (of 6), and it is very thorough.
