Expanding drive space

[sarah8311]

Hi there. Please forgive me as I am a complete newbie with Ubuntu and Linux. I know Windows really well though.

My situation is that I just recently installed Ubuntu on a computer to run the FOG server for me. This machine is Ubuntu only and there is not a Windows dual install. I bought this machine with 2 1Terabyte drives. Is there a way to extend the drive on to the second 1Terabyte hard drive without losing what I've already set up?

If what you want is to be able to treat the two physical drives as one logical drive -- you're asking to "span volumes" -- which is a RAID function.

As far as I know, there is no way (in Linux) to convert two "basic" volumes to a single "spanned" volume without losing the data.

You CAN expand existing RAID volumes (e.g., adding more drivers), but you have to start with a RAID volume.
