My disk is almost full, how can I know where takes away the most disk?
Because yesterday the disk is enough for my System.
[root@ha-node1 log]# df -lh Filesystem Size Used Avail Use% Mounted on /dev/sda2 18G 18G 4.3M 100% / devtmpfs 3.9G 0 3.9G 0% /dev tmpfs 3.9G 54M 3.8G 2% /dev/shm tmpfs 3.9G 383M 3.5G 10% /run tmpfs 3.9G 0 3.9G 0% /sys/fs/cgroup /dev/sdc 20G 45M 19G 1% /mnt/sdc /dev/sdb 20G 83M 19G 1% /mnt/sdb tmpfs 781M 0 781M 0% /run/user/0 Use du. Use -x to prevent recursion into other mount points. You can limit the output using --max-depth=N. Human readable format (e.g., 1K 234M 2G) is enabled by -h.
Output can be sorted by piping to sort.
For example:
du -x --max-depth=3 -h / | sort -h I recommend ncdu: https://dev.yorhel.nl/ncdu:
Ncdu is a disk usage analyzer with an ncurses interface. It is designed to find space hogs on a remote server where you don't have an entire graphical setup available, but it is a useful tool even on regular desktop systems. Ncdu aims to be fast, simple and easy to use, and should be able to run in any minimal POSIX-like environment with ncurses installed.
ncdu will present a list of directories sorted by their size, for example:
