Editing Jail Server Install (section)

=== make a data partition ===

IF you didn't format the data partition during sysinstall:

Create a g partition on 2nd mirror – bsdlabel no longer works (below shows d partition made with sysinstall):

Here's how we USED to do it with bsdlabel:

 bsdlabel -e /dev/mfid0s1

given:
<pre># /dev/aacd0s1:
8 partitions:
#        size   offset    fstype   [fsize bsize bps/cpg]
  a:   262144        0    4.2BSD     2048 16384 16392
  b:  4194304   262144      swap
  c: 143363997        0    unused        0     0         # "raw" part, don't edit
  d:   524288  4456448    4.2BSD     2048 16384 32776
  e:   524288  4980736    4.2BSD     2048 16384 32776
  f:  6291456  5505024    4.2BSD     2048 16384 28552</pre>

new offset = 6291456 + 5505024 = 11796480<br>
new size is size for 'c' partition minus the new start from above<br>
143363997 - 11796480 = 131567517

So:<br>
 g: 131567517 11796480 unused 0 0
