vinum disklabel FBSD 5.2.1....

[matt virus]

Hi all!

I have (8) maxtor 160gb drives I plan on constructing a vinum raid5 
array with.

the devices are:

ad4....ad11

All drives have been fdisk'd and such,
ad4s1d.....ad11s1d

The first step of setting up vinum is changing the disklabel
disklabel -e /dev/ad4

The disk label says it has 8 partitions, but only the A and C partitions 
are shown...

**********MY DISKLABEL********
# /dev/ad4:
8 partitions:
#        size   offset    fstype   [fsize bsize bps/cpg]
   a: 320173040       16    unused        0  0
   c: 320173056        0    unused        0  0 # "raw" part, don't edit

******************************

Now, i know i have to change *something* to   "vinum"  but i'm unsure 
which one, or if I need to actually add a line or ???

This is my first time playing with vinum, i've read a handful of howtos 
and all the documentation I find shows the disklabel looking like this:

*****HOWTO's Disklabel********
# disklabel da0
[snip]
#        size   offset    fstype   [fsize bsize bps/cpg]
   a:  1024000  1024000    4.2BSD     2048 16384    90
   b:  1024000        0      swap
   c: 17912412        0    unused        0     0
   e: 15864412  2048000     vinum
