I have a 500 GB software RAID that I created using Disk Utility and two 250 GB drives (just needed speed, not so much reliability as it's not particularly crucial data). The drives are SATA but are in a FW800/400/USB2.0 external enclosure.
Does anyone know if there's anyway that I could get the RAID mounted on a Linux box? All my Linux boxen are already set up to mount HFS+ block devices so the only real issue is the software RAIDyness.
