Software RAID on Ubuntu 8.10 desktop

peterhocking · 03-29-2009, 04:48 AM

Hi

I'm new to Ubuntu & linux generally. Ive installed 8.10 on a PC with 1 X 500 gig hard drive & 2 X 750 gig hard drives.

Ubuntu & all the apps are installed on the 500 gig.

I want to set the 750 gig drives as a RAID 1, (mirrored), array.

How do I do this?

TIA

Peter

You have to install Ubuntu using the Alternate CD.

When you come to the partitioning screen, select manual. Then format both your 750 gig HDs selecting "Volume for raid" as type (or something like that).
Once done, in the partitioning screen you will see another entry called "Configure software RAID", where you can choose RAID type and drives used.
Then you will see a new "partition", /dev/md0, which is your raid array. Format it as you wish, you can even use LVM on that.

Other than re-installing from the alternate-install CD, is there another method.

I've just got it working nicely as a MythTV backend & I'd rather not have to to redo it
