Weird laptop issue

4/25/2008

I’ve been using Fedora 9 since the Beta release came out a month or so ago with few problems…I did a fresh install when the Preview release came out last week. I love it! Only a few small, annoying issues so far.

I was having wireless issues but only at home…That seems to be due to a weird WEP issue and is solved by switching to WPA which I should have done a while ago. Now for the other weird issue…I have my /home, / , and swap encrypted using LUKS. Everything has been fine since the Preview re-install until I got home today..My normal procedure is typing 3 passphrases to decrypt everything when the laptop boots up..

When I got home my swap passphrase wasn’t working…I couldn’t change the passphrase since it seemed to not have a passphrase set…So here’s what I did:

This reformatted the swap partition. I wasn’t worried about data since it’s just swap.

WARNING!
========
This will overwrite data on /dev/sda2 irrevocably.

Are you sure? (Type uppercase yes): YES
Enter LUKS passphrase:
Verify passphrase:
Command successful.


Now to turn it back into swap

[root@voodoo ~]# mkswap /dev/sda2
Setting up swapspace version 1, size = 2146791 kB
no label, UUID=ce65e513-a0b8-3345-a834-a8989a57ac04


And finally turn swap on

swapon /dev/sda2


Really strange that it all of the sudden lost the passphrase…
