Actually, Greg has tweaked things so that you can put / on a Vinum array.

IDE hotswap (particularly if you swap in a disk that's not an *exact* replacement for the disk you took out) is a bit dodgy. If you have a PCI slot, I would recommend looking at 3ware's new 6x00 series controllers. ATA-66, hotswap, reliable bootpath, cheap, etc. The 5x00 controllers are even cheaper, but don't do hotswap. -- ... every activity meets with opposition, everyone who acts has his rivals and unfortunately opponents also.
