How to install Ubuntu in a RAID 0 array - Part 1 - #6

[TheSleepwaIker]

I installed the software raid but can not see the volume. How could it be?

A key thing not mentioned -- linux software RAID applies to PARTITIONS, not to entire disks (unlike hardware RAID controllers), so (for setting up a RAID1 (mirror) with two mirrors) you first make identical partitions and set them to be "software raid" - you THEN tell linux which named partitions (i.e., "/", "/boot", "/home", etc.) to put onto which RAIDed partitions. Software RAID goes in the "stack" just above the physical partitions, but below the partition naming / filesystem location.

Many thanks for this tutorial. My new system has the OS now on a pair of SSD's set-up in RAID 0. Fast. Very fast.

How do you dual boot windows 7 in RAID 0 and Ubuntu on that same RAID?

[eltonrasch]

@sweetasiansugar I need to do it too... but i'm using Back Track 5 instead of Ubuntu... i think the process would almost the same... if anyone knows...

Hi, I've watched several of your videos. They are very well done. Anyways, how did you get the VM to recognize both of the virtual drives? For some reason VB only sees one.

[jmksds]

very urgent!!!

While I installing,it asked like that

serial ATA RAID configurations have been found

do you wish to activate these RAID devices

Activate serial ATA RAID devices? yes or no...

What I shoud shoose??

Followed your video and got root on raid 1. Partytime!

Thanks.

hey friend. I have the Ubuntu 10.10 alternate download and I made it into a USB Flash. However, how can I access that menu? I don't see any options for that. It keeps letting me enter the Ubuntu OS. Thanks

How does the Intel ICH10R Raid utility option ROM affect the setup of a RAID 0 partition. Typically, that BIOS type utility (or others like it) are used to setup the RAID volume. Then during a Windows OS installation, the RAID volume is detected with the parameters it was setup with in the utility.

how would you set this up if it does pick up your raid controller and it is not in two seperate disk, but one big one? I have 2 250gb in a raid 0 already. It won't let me install the os, since i have no idea what i am doing at this point.

Ok, how I was setting up the RAID wasn't working. GRUB would always complain it was "out of disk". I was setting the boot flag on each of the drives with the physical RAID. I'll try without and see if my annoying problems are finally resolved.

Thanks for the tutorial. I have been going crazy trying to install Ubuntu on my Raid 0 made of 2 SSDs.

2 Questions:

1: I take it that this will work with Ubuntu 10.04 as well...

2: Will this mess up the other Operating systems installed on the same Array? I want to install 4 OSes on the same array (Win 7, XP, Ubuntu, & OSX).

Thanks.

@thelegendarypaki

2. Windows does not know about the other raids. You need to setup 4 raids to get it to work. And you should setup one of the unices last because win will *uck over your other OSes.

I would try to work it out in this order:

1. Windows XP

2. Win7

3. OSX (How do you put this on a non Apple machine?)

4. Ubuntu

So, lets say I wanted to give this a try, I would have to create two identical VHD? Does this only work with the alternative CD? Also, would this work with SUN VM?

[robstokes121]

your installing it on a virtual machine how does that work?

[amzertech]

@robstokes121 By creating two virtual hard drives.

Where the hell do you get this ultranet cd? Desktop versions only come in a live cd as far as I can see.

[underthehour2000]

You use the alternative CD of ubuntu found on the ubuntu website lol!
