[arch-dev-public] Devices >2TB

Anyone know if our standard kernels are capable of seeing/handling devices that are >2TB in size? I know you need 48-bit LBA to do this, but clearly 48-bit LBA is supported on the machines I'm using and in our kernel. The 2TB limit, as I understand it, comes from something *somewhere* being limited to a 32-bit address. Is it the kernel, or perhaps my SATA controller somehow? Or the sata_nv driver? The setup is that I'm hooking up a hardware-raid-enclosure external cabinet up via the ESATA port to the SATA controller built into the NVidia NForce 430 chipset on the motherboard. We can't see more than 2TB. Thanks for any helpful hints that people may know! - P
