I just set up my site through AWS EC2 not that long ago from following YouTube tutorial. Now I have issue with no space left on the disk space and I tried to remove some of the old backup files I have. However, when I ran df -h it was showing /dev/nvme0n1p1 7.7G 7.5G 232M 98% /. I never ran into this kind of problem before and my site is still down. Is there a way to clean anything in nvme0n1p1? Thank you. (My site is very simple it just show some contents only nothing fancy)

➜  ~ df -h

If the system is consistently running out of space, check that it’s not your log files in /var/log that are causing the shortage. If you’re using Apache or nginx, check that those logs are also being properly cleaned up.

  • Hi, I'm not sure if I'm doing it correctly, I ran df -h /var/log and got Filesystem Size Used Avail Use% Mounted on /dev/nvme0n1p1 7.7G 7.5G 232M 98% /. So is that mean it was from the log that causing the shortage? and if so, how do I clean it? Thank you. – 14079_Z Nov 23 '20 at 05:40
  • To check the size of a directory, you'll want to use du ⇢ sudo du -hs /var/log –  Nov 23 '20 at 05:42
  • Hi, just did it and got 791M /var/log return. – 14079_Z Nov 23 '20 at 06:35
  • Well, the next thing to do would be to du every directory and find out where all of your storage is being used. You can query the whole system like this: sudo du -m / | sort -nr | head -10 ⇢ Note: this query will take a long time to run, depending on how many files and directories you have on your system. Do not be surprised if it takes 5 minutes. –  Nov 23 '20 at 07:03
  • Thanks. I just did and update the post with the result. So it looks like the path / and /usr is taking the most of the space? It is not an actual file so I don't know how to remove it or if it is safe to remove anything. I did sudo find / -type f -size +100M -exec ls -lh {} \; but got -r-------- 1 root root 128T Nov 23 17:45 /proc/kcore find: ‘/proc/1616/task/1616/fdinfo/6’: No such file or directory find: ‘/proc/1616/fdinfo/5’: No such file or directory. Pretty sure I'm not doing it correctly lol. – 14079_Z Nov 23 '20 at 17:51

For me it was logs, but not in /var/logs. They were underneath the root where my docker container was deployed, mounted as volumes.
