Installing ubuntu on Raid 0

I have a computer set up with only a software raid 0 set up (2 hard disks). I already have made partitions for ext3 and swap. But how can I install ubuntu on my system now?

When I install through ubuntu alternate install disk (which detects my hard disks fine) when install finishes I cant load ubuntu because it complains about not being able to mount / or something like that..

    I did it all manually, also I set the / at the correct partition. I cannot switch the hard drives around because they are on a RAID 0 set up, which mean I will lose all data!

    Boot seems to go fine as far as ubuntu go, and / point is set up properly, but it just halts when it tries to mount devices! I hope the problem is clearer now!

    I already have a windows partition but problem is not grub getting confused. As mentioned in the extra comments system halts when it tries to mount devices (not an I/O error)

I have yet to try RAID, but i want to. Best idea I've heard was from a guy that set up the first hard drive with a small /boot partition in addition to the swap and ext3 ones... I guess that way, GRUB didn't get confused.

Ok I have Duo booted ubuntu a couple of times now. When you were partitioning did you use the automatic or he manual? Since you have two hard disks, I will assume you use a desktop and you know how to take it apart. So, if you did automatics the bestt I can tell you is to swith your hard drives around physically and if that fails try switching g the boot menu order. If you used manual partitioning then when you were creating the ext3 partition you did not type / in the text box labeled Moint Point (that's the best I can help you) I hope this has fixed your problem. GO UBUNTU

Having trouble booting two Raid-0 discs on Asrock Z77 Ex4 UEFI


RAID implementations will vary from controller to controller, and even from bios to bios revision or version for the same controllers.
You should "image" the raid on the old board, then delete the raid on the old system.
In the new system, you need to treat these drives like they are new, blank hard disks. Any partitions will need to be removed, and the RAID created on the new board. Once this is done, you can use your partition imaging software to drop the data back onto the new RAID partition. Seagate I believe has imaging software available in Seatools, or you can use something like Acronis True Image or GHOST.

You can recover RAID data from hard drive with RAID recovery software easily.
Tenorshare Data Recovery Enterprise is a comprehensive data recovery software that supports RAID recovery for RAID 0 and RAID 5. Lost data in RAID 0 and RAID 5 can be deeply scanned and restored immediately. Meanwhile, files and folders in RAID 0 and RAID 5 can be copied to other partitions directly. http://www.any-data-recovery.com/product/datarecoveryenterprise.htm

I upgraded matheboard from p6t6 (stopped working for some reazon) to p6t7. My hard drives have been set up to raid. I have windows 7 ultimate installed. I set bios to raid and choose proper disc as boot 1...


On many systems with RAID1 support built into the mobo chipset, that system includes some RAID management software in BIOS. You won't see it until you turn on RAID capabilities in the BIOS and add a drive. But you might find all the details you need in manuals on the matter from Dell, so look for those. They could have come with your machine, or you may have to search their website and download.

On systems I've seen you create and manage RAID arrays using that built-in software, NOT Windows tools. In fact, some RAID1 management tools would allow you to convert a single stand-along HDD to a RAID1 array by adding a matching HDD unit and then having the system copy all the data to the second drive. This is almost the same as the process to repair a damaged RAID1 array by replacing one faulty drive with a new one and rebuilding the array.

HOWEVER, Windows ALWAYS needs a RAID driver installed in it to use any RAID array. If you are simply booting from a "normal" stand-alone disk into Windows and then using a RAID array as a data storage system, the RAID driver installation can be done any time after Windows is running as you set up the new storage system. BUT Windows in ANY version cannot BOOT from a RAID array unless the RAID driver has been installed at the very beginning of the OS installation. This implies that, if you want to convert your single disk into a RAID1 2-disk array and use ONLY that as the HDD resource in the machine, you will need to re-install Windows, this time including the required RAID driver install at the beginning, in order to boot from that array.

I have read that there may be ways to convert a non-bootable RAID array into bootable by some complicated editing of Windows registry and boot files in order to force it to load the right driver at the right time from the right spot on a HDD, etc. But I am not SURE that would work. It's definitely for the adventurous knowledgeable techie.

So here's a quick guide to installing hardware RAID on a motherboard that features a RAID controller. These steps assume you are performing a clean Windows 7 install rather than an upgrade, and they might differ depending on your system set-up, but the general principles should be the same.
  1. Download the RAID drivers for your motherboard from the manufacturer's website and save them to a memory stick.
  2. Back up all your important data!
  3. Turn your PC off and unplug it.
  4. Install 2 hard disks preferably with identically capacity into your PC.
  5. Turn on your PC, press the delete key or F2 key when prompted to get to the BIOS menu.
  6. Find the option to select the RAID mode, save your settings and exit BIOS.image.axd?picture=bios-raid-options.jpg
  7. On reboot you should see a new menu option to enter the RAID controller settings. Enter the key combination when prompted to get to the RAID controller menu. image.axd?picture=amd-raid-menu.jpg
  8. Create a new RAID array selecting either RAID 0, or RAID 1.
  9. Select the disks that will form the array, save the settings and exit.
  10. On reboot press the delete key or F2 key when prompted to get to the BIOS menu.
  11. Check the boot sequence of your PC and ensure your optical drive is top of the list.image.axd?picture=bios-boot-sequence-options.jpg
  12. Insert your Windows 7 disk into the optical drive and exit the BIOS.
  13. On reboot press any key when prompted to boot from the optical drive.
  14. Windows 7 should start installing.
  15. Select your localisation settings and click next.image.axd?picture=localisation.jpg
  16. Click "repair your computer" and click the "load drivers" button.image.axd?picture=windows%207%20repair%20menu.png image.axd?picture=load-drivers-option.jpg
  17. Insert your memory stick and browse to the correct driver and install.
  18. Exit back to the Windows 7 install menu click "Install now" and on the next screen click "Custom (advanced)" to perform a clean install.image.axd?picture=install-windows-custom_thumb.jpg
  19. When you are asked where you want to install Windows 7 you should see that the 2 RAID hard disks are now visible as just 1 drive.
  20. Add a partition to the new drive so Windows with be able to recognise it.
  21. Continue installing Windows as normal.

1. If you are just setting up your computer to have an a regular HDD and Backup HDD, i would think you should be able to set that up by booting onto your computer regularly, go to start, then into My Computer and right clicking on the HDD you want to set as Raid 1.

But if just want that other HDD for Space on your computer, all you had to do was plug it in and there you go... extra space.

Now if your installing windows 7 on the other drive i would find that pointless because you already have it on your first drive unless your putting 2 operating systems onto your computer.

Hope this helps.

4 big quadra 6 TB, win7.0 pro,i can see the unit, format it,etc. but always in raid 0, the unit doesn´t change when i tried to reconfigure it to raid 5, and i have followed the lacie instructions


The hard disk might originally came from a computer with raid 0 configuration that is why no matter what you do to reformat, it will always give you the same drive space as your Raid 0. The solution to your problem is actually deleting the partition first from another computer before formatting.

You will be needing a windows installation disk and you can plugin the big quadra thru the usb cable in another computer. Run the windows installation disk (this could be xp or vista) and when it prompted you to choose a task, just press enter to start windows installation (DO NOT press R to go to recovery console). Next, the system will search of every available partition and will show you the drive partition for your Big Quadra. Select for it and delete the partition from there. After it has been deleted, you can cancel that installation process from that computer and try re-formatting your drive into Raid 5 again as you have been doing before.

Should you have any question, please feel free to ask. Good luck!

Gurb hangs after installing ubuntu on raid 0. I left a 500 Mb /Boot (marked as bootable), 1,7 Gb swap on each disk and /root and /home partitions on raid 0 disks each. Installation gave me no problems but...


Hi,
I too upgraded from Ubuntu 9.04 to Ubuntu 9.10 using wubi, the Windows ubuntu installer. Everything was fine, and I even admired the beautiful desktop, added KDE. I was very impressed until came the time to reboot. Grub hung. I entered the console and tried to repair: To no avail.
I reinstalled Ubuntu/Gnome without installing KDE. All went fine until the time to reboot. It hung again. After several trials, I decided to go back to Ubuntu 9.04.

From what I could gather on the Internet, it has to do with the new type of file system ext4. If only I had the choice to use it or not.

Since I was using wubi and was not offered the choice to install the ext4 file system, I do not know whether that choice is offered on a full scale installation without wubi. You might try to find out if you can customize the installation process and not select the ext4 file system, if possible.

One remark concerning the amount of swap space you are setting aside. In my opinion that's too much: I have a 2GB RAM, about 300MB swap space, and each time I monitor swap usage I find it very low to nil.

Concerning Ubuntu 9.10, I will wait until the bug(?) is fixed before upgrading. Good luck to you

I hope it helps
Thank you for using FixYa.

I have hp proliant with raid 1+0 .I have 2 hard and usr in option


Sometimes shortened to RAID 10, RAID 1+0 is a particular combination of two different RAID levels: mirroring (RAID 1) and striping (RAID 0). The appeal of RAID 1+0 is simple: mirroring gives you the highest level of availability RAID offers, with the fastest rebuild times when a disk fails; while striping - using the proper chunk size - is the basis for high-performance I/O.
