Time for Neil to help! :) 2.4 kernels on 32bit processors cannot handle devices larger than 2^32 sectors (2T). Maybe not even bigger than 1T, I'm not sure. 2.6 kernels can if you select CONFIG_LBD (Large Block Devices). > > I think you will be fine if you only use 11 disks! > 195360896 * (11-1) = 1953608960 (this is under the 2T limit). Worth a try, as is using 2.6 NeilBrown - To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
