Let me begin by saying I am a complete beginner using Ubuntu, but I'll try to give as much information as possible. I created a Raid 5 array and formatted it with mke2fs. I was able to mount the image and move over all my media and set up Plex Media Server. All of a sudden I am unable to mount or even find this image anymore. Usually I'd be able to find it in /media/library but there isn't anything there. Here are some of my debugging outputs:

"Ubuntu 3.10" ? Is that 3.10 kernel? Gnome 3.10? Or some obscure Ubuntu I never heard about ;) –  Rinzwind Jan 11 at 17:25
    
Thats just what it says when i go to System Settings > Details. I just upgraded to it (Saucy Salander I think they called it) –  jflatle1 Jan 13 at 3:35
