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?
