Xbian (beta 2) SD Card Full issue

[rizzyc]

My Xbian (new beta 2 version) was constantly freezing on my 4 gig sd card. I decided to install the image on an 8 gig SD card.

However I had my this entire setup (http://www.raspberrypi.org/phpBB3/viewtopic.php?t=47084) with flexget and trakt.tv set up so I didn't want to repeat the whole process so I copied the image of the 4gig installer using Win32 disk imager and transferred it to the 8 gig card.

The pi stopped freezing and has been running for a few days but transmission isn't running because of a space issue.
In Transmission I get this issue
Error: Unable to save resume file: No space left on device


I ran df -h and got this:

Terminal

Filesystem Size Used Avail Use% Mounted on
rootfs 3.5G 3.4G 0 100% /
/dev/mmcblk0p2 3.5G 3.4G 0 100% /

/dev/mmcblk0p2 3.5G 3.4G 0 100% /xbmc-backup
/dev/sda1 1.4T 94G 1.2T 8% /media/media

My transmission stopped working because of space issues now, although I still have 1.2 T of space left on the HD.

I also get this error when logging in through SSL:

Terminal

xbian@xbian ~ $ sudo su
[sudo] password for xbian:
sudo: unable to write to /var/lib/sudo/xbian/2: No space left on device

If anyone can help figure out what is happening, that would be greatly appreciated.
