Guys,
I'm laughing at myself for being unable to get swap activated.
Initially,
when I breezed through the install, I forgot to set /dev/sdb6 to type 82
so the box came up with swap off (2G of ram so not much of an issue)
But now, I want to activate it and I get an error activating swap that
frankly, I have never seen before:
[11:27 dcrgx2:~] # swapon -a
swapon: /dev/sdb6: read swap header failed: Invalid argument
Huh?
Here are the current details of the install:

It looks to me like swap should activate. What am I missing? Thanks for
any insight you can lend here.
you have to create the swap filesystem in to the partion by running mkswap
/dev/sdb6
