    Exclamation Ubuntu Installer doesn't recognize my RAID 10 array

    Ok sorry if this is a repeat post, but I have searched the forums and haven't found any similar problems. Whenever I try to install Ubuntu, it seems to be going fine until I get to the partition step. At this point, there are no drives (even standalone, much less my RAID array). I am attempting to set up a dual boot with Windows 7, which I had working fine with my old motherboard and CPU.

    System specs are:
    ASUS M4A78LT-M Mobo with AMD Phenom X4 955 processor
    4GB of generic RAM
    4x1TB drives set up in a RAID 10 array currently running Windows 7.

    Like I said I can't get past the partition portion of the install. If I run the LiveCD, I can only see 2 of my drives in GPARTED, and it doesn't see all (3) partitions on these drives.

    Any help is greatly appreciated.

    I think you should find the alternate installer disk will play nicer with md / raid

    Just a thought

    Re: Ubuntu Installer doesn't recognize my RAID 10 array

    Hi there, welcome.
    You have what is known around here as a Windows software RAID or fake RAID or dmraid. This is a different system to linux software RAID or md RAID or mdadm.
    If you are installing 11.04 it has the dmraid drivers already installed.

    I dont have any experience of this but if you boot live CD you should be able to see and mount the array in the Places menu. If not, open a terminal and run sudo dmraid -ay first. Then run the installer and hopefully the partitioner will see the array as a single device. There may be difficulties with the Grub boot loader installation: I believe it needs to be installed to the device name of the array, /dev/mapper/xyz

    I would use Windows to reduce itself to make empty space for Ubuntu rather than GParted.
