Is it possible to create a software Raid1 with Ubuntu 9.10 after installation?

Hi,

I have Ubuntu 9.10 Running on my desktop, using a 500GB HDD. I have now added a second 500GB HDD. I was wondering if there was a way to build a Software RAID 1 under Ubuntu 9.10 without reinstalling everything?

Thank you

Best regards

This is a guide for converting a Linux system to RAID, although it's written for RedHat, you'll get a good idea of how to make the conversion. It's quite complex.

The link provided a a very in deep procedure has you will see it's not a trivial process.

I would start by just mirroring your /home filesystem if you have a separate home partition, because this is where your personal data is.

After that you can just backup /etc in /home/backup and you have a miror copy of all important data.
