So I already have a 300 GB SATA drive with Ubuntu 8.04 installed on it. It is currently running off my mobo's onboard SATA 1.0 Raid Controller. I recently purchased a SATA 2.0 Raid PCI controller card that I will be putting in the computer and 2 new 750 GB Western Digital Caviar Green Hard drives. I wish to add the two drives in a Raid 1 configuration to store all my Pictures, Files, and Movies on. Every instruction and tutorial I can find on setting up Raid on Linux assumes you are performing a fresh install on Linux and gives no tips or instructions for current installations. ( I have found some explanations for doing it with software raid) I already have Ubuntu installed and do not wish to have to reinstall it. I want to leave my installation on the 300 GB drive and just add in the 2 750GB drives for storage. I feel like I should just be able to add the card, install the drivers, mount the drives and that is it, but rarely are things that simple I have found. Any tips or links?
