You should use gpt instead. Do you want the entire array as one partition? # gpt create /dev/da0 # gpt add /dev/da0 # newfs -O2 -U /dev/da0p1 (or 'newfs -O2 -U -i 524288 /dev/da0p1' if you have mostly multi-megabyte files) If you want multiple partitions you will have to pass a size (in sectors) as a parameter to 'gpt add'. Beware that you might not be able to fsck the filesystem because of its size. I'm not sure how well gjournal handles fsck of large filesystems. Personally I'm going with ZFS for my next large array (8x750GB). /Daniel Eriksson
