I have a linux box on my school's server. When I was trying to install
Protocol Buffers, disk usage is reported as exceeded. So I checked my disk usage by two command on my home directory:
du -h 535M . df -ha home.XXX:/export/home/XXX 9.7T 1.5T 8.3T 15% /home/XXX
Are they supposed to be same number? Which one is the real usage of my disk on Linux box?
