check which folder occupies more space. and try to clear that.
du -h / | grep "[0-9]G"

maybe you can try search big size files..
for exa +~10 MB
find / -mount -type f -size +10000000c -exec ls -lh {} \;

Well, you did not say how full it is ordinarily...for a great "classic" is you pass from 40% to 100% the next day because someone did a backup and misspelled the device...
