Pihole Disk Shortage 99% usage

[cdwebb0]

I'm getting an error that /var/log is 99% full.

Error:
Disk shortage (/var/log/pihole-FTL.log) ahead: 99% used
/var/log: 83.9MB used, 83.9MB total

I've set the "/etc/log2ram.conf" SIZE=80M from the default 40M and "/etc/systemd/journald.conf" #SystemMaxUse=40M. This fixed the issue for a few days before it filled again. How do I stop /var/log from filling so quickly and what can I clean up?

Try to use logrotate, pihole has config for it in /etc/pihole/ file named logrotate

This will show you what files are your problem:
sudo tree /var/log/ --du -h

more info, check compress option:
