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

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

I am using command df -i to find

du -h -d 1

cd /lib sudo du -h -d 1

CodePudding user response：

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.

Check the user .pm2/logs directory, if your node app as errors or many regular logs this can increase disk space used.
