When installing Ubuntu 12.10 for the first time, I made sure /home had it's own partition, gave it about 185GB, and gave root ~10GB. Now root is almost full after a few days and I've noticed that root is as big as /home and some additional MB from some actual root files. Note that I deleted some unused files in /home to make sure it really affects how much space is used in root, and it clearly does. (checked in gparted) I've also made sure the files I am talking about are actually in /home/myname/ and not just in root's home.

df -h spits out this information:

df: `/root/.gvfs': Permission denied

/dev/sdb4       729G   87G  642G  12% /media/mave/Storage

I cut out my windows partitions as I don't see any relevance.

I hope this is enough information for someone to tell me what I did wrong
