I have a VBox VM running CentOS 6.7 and I want to extract the content of a 14G tar file. I'm doing as: *tar -xvf www.tar.gz* But I am getting a lot of errors like the ones shown below: html/elclarinweb.dev/wp-content/uploads/2015/03/12-Aura-Ávila-400x320.jpg tar: html/elclarinweb.dev/wp-content/uploads/2015/03/12-Aura-Ávila-400x320.jpg: Cannot open: No space left on device html/elclarinweb.dev/wp-content/uploads/2015/03/Julianne-Moore-11-585x378.jpg tar: html/elclarinweb.dev/wp-content/uploads/2015/03/Julianne-Moore-11-585x378.jpg: Cannot open: No space left on device So, trying to find why the VHDD (Virtual HDD) has left out of space I ran the following command: *df -h* Filesystem Size Used Avail Use% Mounted on /dev/mapper/vg_server-lv_root 26G 24G 869M 97% / tmpfs 2.0G 0 2.0G 0% /dev/shm /dev/sda1 477M 80M 373M 18% /boot And then I've tried to find the conflictive files by running: *du -hsx * | sort -rh | head -10* du: cannot access `proc/3662/task/3662/fd/4': No such file or directory du: cannot access `proc/3662/task/3662/fdinfo/4': No such file or directory du: cannot access `proc/3662/fd/4': No such file or directory du: cannot access `proc/3662/fdinfo/4': No such file or directory 14G var 1.8G usr 278M lib 77M boot 31M etc 27M lib64 15M sbin 7.8M bin 188K dev 112K root Why *df -h* is reporting 24G used? Where the space did go? How I can fix this?
