You need to provide more information. What is telling you the filesystem is full? What is telling you there is still available space? What is the output of "df -h" and "df -i"?
It's probably one of two things:
1) You're looking at multiple filesystems. One of them is full, the other is not.
2) You've run out of user space on the filesystem, but there is still some space left that's reserved for root only (defaults to 5% on ext filesystems).
