Hello Doug

Initially I thought 'of course I've done a newfs' and then I read what
you'd actually written, had I done a newfs AFTER I'd create the RAID. Which
I hadn't, now I've done so I get to see the sum of all three stripes.
Thank you very much indeed. I can now get on with using it!

Thanks again
Mark
