gpart -t freebsd-swap

[Erratus]

# gpart show ad4
=>       63  488397105  ad4  MBR  (233G)   
         63   81915372    1  !7  [active]  (39G)
   81915435  190466640    2  !15  (91G)

  446349960   42047208       - free -  (20G)

Now the red line shold become the swap-slice:

# gpart add -b 272382075 -s 16771860 -t freebsd-swap ad4
gpart: Invalid argument

BUT this works

# gpart add -i3 -b 272382075 -s 16771860 -t freebsd ad4
ad4s3 added

Now, why "-t freebsd-swap" does not work, and how do I get swap on ad4s3?

Ok, the question was missing.

How do I do get the swap on slice 3?

OR

What's wrong with this command:

# gpart add -b 272382075 -s 16771860 -t freebsd-swap ad4
gpart: Invalid argument
