On my ubuntu 11.10, /dev/sda3 (150GB) is mounted on / and /dev/sda1 (80GB) is mounted on /home. My entire disk has 250GB and the system is reporting I am running out of disk space. Here is the output of df -h:
Filesystem Size Used Avail Use% Mounted on /dev/sda3 149G 141G 0 100% / udev 3.9G 4.0K 3.9G 1% /dev tmpfs 1.6G 860K 1.6G 1% /run none 5.0M 0 5.0M 0% /run/lock none 3.9G 508K 3.9G 1% /run/shm /dev/sda1 74G 15G 56G 21% /home
Ubuntu disk usage analyzer report the same thing. But this is weird because I believe I never used that much space on /. I also checked every individual directory under / ( exclude /home ), and they don't use that much space:
8.8M bin 4.0K dev 0 initrd.img 0 initrd.img.old 828M lib 15M lib32 4.0K lib64 4.0K media 0 proc 9.2M sbin 0 sys 1.1G var 108M boot 18M etc 4.0K mnt 40K root 4.0K selinux 72K tmp 0 vmlinuz 0 vmlinuz.old 16K lost+found 133M opt 1004K run 4.0K srv 5.9G usr
Any one could give me some ideas what is using up the space? Thanks in advance.
