You're probably going to run into "boo hoo hoo hoo". Most likely you won't be able to get over the 2TB limit. Also don't use sysinstall, I was never able to get it to work well. Probably because my arrays were mounted over fiber channel and fdisk craps out. This is what I did: dd if=/dev/zero of=/dev/da0 bs=1k count=1 disklabel -rw da0 audo newfs /dev/da0 That creates one large slice, UFS2, for FreeBSD. Let know if you get it over 2TB, I was never able to have any luck. Another reason you might want to avoid a super large file system is that UFS2 is not journaling. If the server crashes it will take fschk a LONG time to check all those inodes! Ben.help
