Hum, is/was this documented somewhere? I just set up two RAID-5's on -STABLE, and I have done this every time I did a RAID setup with vinum. I'd hate it if I'd have to migrate 300GB of data because I didn't reserve 16 sectors at the start of a disk :( --Stijn -- If today is the first day of the rest of your life, what the hell was yesterday?
