Hi Todd, Having finally gotten the time to read through this entire thread, I think Ralf said it best. ZFS can provide data integrity, but you're reliant on hardware and drivers for data availability. In this case either your SATA controller, or the drivers for it don't cope at all well with

Howdy yall, Earlier this month I downloaded and installed the latest copy of OpenSolaris (2008.05) so that I could test out some of the newer features I've heard so much about, primarily ZFS. My goal was to replace our aging linux-based (SuSE 10.1) file and media server with a new machine run
