my system warned me that I only have a gig of space left. But when I open the disk usage analyzer and scan the filesystem / is 96% full but none of the folders it contains show they are full at all (except home which is on it's own partition. The directory of / shows that it is only 7600 full :

bmike1@c521 / $ ls -l
