    Default Reinstall 11.1 - "import"/rebuild Software raid 5

    My motherboard is acting up and can only boot up with 3 out of 4 SATA disks.
    The disks are as follows
    • 1 * 640 GB
      Divided into:
      • / 30'ish GB
      • /home
    • 3 * 1 TB in software RAID 5
      • mounted as /home/username/Shared
    • 1 * 120 GB (IDE instead of SATA, not relevant to the problem)


    The PC with the above disks has openSUSE 11.0 x86_64 installed on the 640GB disk and as such to keep it operational with just 3 SATA disks I had to disconnect one of the RAID array disks.

    A new motherboard as well as a new processor are already ordered to replace the faulty hardware. (old setup is s754.. can't find a proper replacement motherboard :<)

    As openSUSE 11.1 will be out soon I'm planning to do the replacement of the hardware at the same time, how do I go about rebuilding the raid 5 array? (as one disk is obviously out of sync now)

    I've now replaced the hardware, a bit more then I originally intended to.. new motherboard, RAM, processor and videocard. Anyways.. I installed 11.1 and it went pretty much flawless. The installer picked up my old situation and made me the raid with 2 out of 3 disks again. Although I selected import mount points during the install it was ignored not much of a problem as I successfully mounted it via Yast Control Center > System > Partitioner.

    Now I'd like to add my third disk back to the raid array so I actually got some redundancy as at the moment if one of the 1 TB disks dies all the data is gone.. However under Yast Control Center > System > Partitioner I can't seem to find an option to add it to the existing array.

    Now as pictures tell more than words.. this is how it's set up, and I basically want the /dev/sdd disk back in the array.
