What's causing the memory to blow up?

Question

I just pull a docker image, and it is just a small file. And /dev/nvme0n1p5 uses about 100GB. So What's the problem? How to solve it? Thanks

Answer 1

I found my disk actually has space, just nvme0n1p5 shows this problem. So I tried to find the problem. Finally I found /etc/docker/daemon.json file has a ridiculous config. I wrongly set the data_root, so I modified the data_root to /var/lib/docker to solved my problem. Now the disk succeed to have adequate space. success
