Plesk server running out of space

Problem:

Plesk is running out of space

Solution:

1. SSH into the server
2. Run du -h to see what’s eating up space
3. Or run du -sh * | sort -rh per folder to narrow down the file size

(du -x / |sort -rnb |more)

1. In this case, it was /var/log file
2. I found a log file called modsec_audit.log-202010120.gz
3. Deleted the file
4. Do not delete modsec_audit.log
