So i decided to repartition my sustem in place today. I was fed up with there seeming to be not alternative CD for 13.04 so just went with the default encrypted lvm option on the live cd installer. When I went to examine the mostrosity this set up, i wasn't too impressed. It seemed to set up 3 real partitions, one for EUFI, one for /boot, and then the big one for lvm. In the lvm, it only created two partitions, root and swap. I wanted a third home partition so when I had the time I decided to fix that. I booted up a live CD, resized my root to as small as it would go, and made a new home. I think at this step I screwed something up because now my root is saying that it's 100% full when it's not.

Filesystem                   Size  Used Avail Use% Mounted on

This isn't the end of the world. I can still write to the supposedly full disk fine, but I have a bunch of applications that are complaining or otherwise acting up because of it. Is there any hope for recovery? Or should I just save my home and make a new root partition?
