[Nexus S 4G Android Development] elementur:
Edit: I have fixed the issue and everything is working as it should.

I seem to have a problem when trying to do a nandroid backup. It's saying that my SD card is full and the process cannot be continued. My SD card is far from full. I still have 12GB left. Below is the recovery log.

Starting recovery on Sat Oct 8 13:47:06 2011
can't open /dev/tty0: No such file or directory
framebuffer: fd 3 (480 x 800)
