I have this ASUS M2NBP-VM motherboard http://tinyurl.com/3xby3h running CentOS 4.4 as a web/email server. It has a 500Gb SATA2 drive with about 32Gb in use.
The motherboard supports hardware raid. Is there a way to switch to RAID1 without reinstalling or loosing any data?
Also, if I am running raid how do I know if there is a failure on one of the drives anyway? Is hardware RAID1 a good idea?

Like most here, I would suggest going the software Raid route. The performance is about the same As I learned earlier this week you can move a software raid to another system of even distro. It totally independent from the server hardware. To create a Raid just google "mdadm software raid" and you get lots of information. As far as monitoring: Smartmontools will email you when a drive fails or is about to. Look at /etc/smartd.conf for details. Just remember Raid is not a replacement for a good backup plan it just provides fault tolerance.
