What is taking up so much space on my disk, beside the filesystem?
I have a storage drive (2TB) and an OS drive (90GB SSD). I've run out of space on the OS drive:
/$ df -h Filesystem Size Used Avail Use% Mounted on /dev/sdb1 72G 72G 0 100% / udev 5.9G 12K 5.9G 1% /dev tmpfs 2.4G 1.2M 2.4G 1% /run none 5.0M 0 5.0M 0% /run/lock none 5.9G 428K 5.9G 1% /run/shm /dev/sda1 1.9T 639G 1.2T 37% /media/StorageDrive
So be it. But when I attempt to figure out where the space has gone, I cannot find it anything remotely approaching the capacity of the drive:
/$ sudo du -h -d 1 du: cannot access `./media/StorageDrive/home/ari/.gvfs': Permission denied 675G ./media 2.3G ./var 0 ./proc 7.0M ./tmp 27M ./boot 4.0K ./lib64 12K ./dev 44M ./home 16K ./lost+found 8.0M ./sbin 223M ./lib 4.0K ./selinux 1.4M ./run 140K ./root 8.8M ./bin 4.0K ./mnt 38M ./etc 8.0K ./srv 4.8G ./usr 65M ./opt 0 ./sys 682G .
Note the difference between the total (682G) and the mounted drives in /media (675G) is only about 9G. How are 72G being used? Where is this dark matter hiding?
