[arch-dev-public] Devices >2TB

[Paul Mattal]

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!
