I'm wondering if this is my problem with my new/still_creating setup. I 
tried transcoding a show and watched the file in the video dir get 
bigger. Then, I went and did some other stuff. A bit later things 
started going weird - machine started to slowdown. I looked at the 
processes and nothing out of the ordinary at all. I rebooted a bit later 
and then couldn't boot == after a couple of hours seaching I found that 
fstab was there but nothing in it and my swap partition was gone. I 
wouldn't think that this would ever happen except I built this box on a 
20GB drive. So, it's comparitively small setup.

Now, I have no swap partition and my main partition keeps filling up! I 
need to now try and repair this.
