I ran into an interesting problem. I got the last two disks for my 8 250GB disk RAID 5 array yesterday and when I went to create the partition, fdisk freaked refused to make it the total size of the array. Instead it came back with my request to create a partition of 2147483647 sectors, which I really didn’t request. Near as I can figure, something in fdisk’s programming won’t let you create anything bigger than that (that just happens to be the largest signed integer size in c, so I think it could just be a programming issue). To get around it, I was told to use disklabel -w -B da0 to create the partitions, and then newfs /dev/da0a to make my new file system. It worked wonderfully too…
