Error: ENOSPC: no space left on device, write pm2 server

I am not able to identify what is causing my ec2 disk space to reach 100% of capacity. I have a script which deletes files in tmp folder.But still randomly sometimes my disk capacity reaches 100%. I have attached the logs of df -i to show disk utilization.

Error

du -h -d 1

Solution

  • You can use the dh utility

    cd /
du -h -d 1

    it will show the disk usage for every folder in /, then you can cd in the biggest ones and repeat the same.

    You can also run

    du | sort -n

    and you'll get (after a while) all the folders size in the filesystem (ordered by ascending size). By my experience I'd take a first look at /home, /tmp and /var.
