Where does disk space go?

Question

linux

Hey!

There is a simple VDS on which 3 scripts work. The scripts themselves weigh no more than 20mb, operatives eat no more than 100mb each. 5 GB virtual disk.

But but the space on the disk disappears somewhere, I don’t understand this. My logs are deleted immediately in scripts with the -dlog key.
That is, if you look at the directories, then the system occupies the basis, where did the rest of the 2 Giga go?

Answer 1

ncdu /

Answer 2

By standard means:
du -h --max-depth 1 /
see which folder occupies a large volume, and then gradually go deeper
du -h --max-depth 1 /<путь до жирной папки>
until you find where the space disappears
