How to understand what's taking up space?
Hi, I am using Ubuntu 10.10.
I have 40G of disk space in my partition /home and have used up 10 G of it, so I should have 30G left. But somehow disk space disappeared almost completely. I don't know what ate up the disk space. I checked with
ps ax and then
du and couldn't find strange activities.
I would need to reboot the system to recover the free space! Any ideas?
