people can and do have >2T filesystems now. some people on x86 have hit the 16TB limit and others are large still with 64-bit CPUs

for 32-bit CPUs

LBD is in 2.6.x and is required for >2TB but sometimes that means >1TB or even smaller depending on the drivers
many drivers simply won't go above 2T even with CONFIG_LBD so you need to poke about and see what works for you (or use md/raid to glue together multiple 2TB volumes) - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
