Break Raid array without raid controller. (Warning! Wall o' text)

post #1 of 10
Thread Starter 
So here is my situation.

Set up a raid 0 on an Asus Rampage Formula x48. The board died and can't boot. So I threw together with an Asus P5QPL-AM with an intel G41 + ICH7 controller that doesn't support raid. Since my windows was down and I have new drives coming I just planned to temp install Ubuntu 11.04 until the drives come in and the board is replaced. Now I just connected one of the drives and wiped and formated to ext4 for the install. Now when I go to install it I get an "ubi partman error 141" and have to reboot before I can do anything else. I have tried this with both drives separatelyand get the same error. So I plugged in both and figured I'd format both at the same time. When I opened Gparted Partitioner I got a nice surprise. My raid set up showed (even after formating both drives multi times in various formats) and both drives show up separately. And just for laughs I gave in install a whirl before I formatted. And to my surprise it installed but of course wouldn't boot due to corrupt file system. So back to the live CD.

Now after a quite long winded story, my question is. How do I break a raid array without a raid compatible mobo? I'm up for giving anything a shot.

...

The system board without RAID sees each drive independently; 'the RAID is already broken'.

I thought too. But it also sees them as a whole.


They are two different sized drives. One is a 160gb, the other is a 320gb. I know I'm wasting have of the larger drive but I wanted to give a raid a shot. When I set up the raid on the Rampage Formula I set the array for 320gb.

To be honest I thought all onboard Intel controllers were the same so drives in a RAID setup would be easily migrated (unless you deleted the array via BIOS/RAID Config)...I personally never done that though. That's my answer in theory of what happened in your situation as the whole thing was still intact as formatting wouldn't really do much except to tell the computer to overwrite/omit whatever is already on the drive (drive data remains until it is overwritten or destroyed physically).

I just don't understand why you aren't able to to deal with the drives separately. You can always go through the trouble of purchasing an external enclosure...treat each drive as an external...then format each drive from there. Maybe it has something to do with installing Ubuntu 11.04 instead of Windows.

OK, I guess Ubuntu picked up the RAID...

I'm embarrassed to say I don't have any experience configuring RAID with on a linux workstation.

But I thought you'd be able to see the drives in gparted and format from there, install, ect.

The ICH7 doesn't support raid so I don't see how it could see a raid. It does make sense that formatting may not work now that you explain it that way. If I had another board or external setup I'd give it a shot also.

So this brings up another question then. Is their as software that can just nuke all the data on a drive and start it over as a blank slate?

Can Ubuntu read a raid on a non raid controller? Trust me I don't have much experience either. I'm just too lazy to install windows when I'm just gonna have to do it again in less than a week.

Well I seem to have fixed it. Used Killdisk to completely wipe the disk.
