RAID status

I have a server running CentOS 4.2 with a 600GB RAID-5 array of three 300GB disks on an Adaptec 2410SA controller. This is working great (it can saturate gigabit Ethernet on reads) and I've had no problems to date.

But I'm just a bit concerned about the redundancy. How do I know when one of the disks has failed? I can't find any information on how to obtain the status of the array.

If someone could point out a way, I could write a little cron script to check it and email me if something has gone wrong. RAID status
