The BSD label cannot handle such large disks. Instead, if you are just using the disk for data you can newfs /dev/mfid1 directly and use it as a filesystem, or if you need to partition the disk you can use gpt(8) to do so. If you need to boot from such a large disk you will need to use the GPT boot code in HEAD (I will backport it to 6.x and 7.x soon). I've successfully used it to boot on 2 TB mfi(4) volumes. Unfortunately sysinstall doesn't support GPT at all, only the older MBR + BSD label method. Note that this problem has nothing to do with mfi(4) at all, but it is a limitation of the BSD label + MBR that applies to any volume >= 2 TB. -- John Baldwin
