Best way to reduce disk size?

[Pollard]

For some reason my disk size grew to over the default 32GB now my network service wont start. What's the best was to get the size back down so I can installed parted and extend it?

Just downloaded the GParted.iso mounted and did it from there easier than I thought. How can I find whats eating all the space I don't think it should be 32GB not much running on there. just portainer with maybe 2GB of apps.

I'm trying to assemble useful advices for this fixed disk space scenario.

1) given a disk space maximum hit, du -h / 2>null | grep '[0-9]M' or find . -name *.tgz files are typical short-term advices.
    If necessary, rm -f <files> in /var/log, tdnf clean all, uninstall unnecessary packages, etc.
    configure log rotation eg. using the logrotate package (tdnf install logrotate-> see /etc/logrotate.conf)
    configure log rotation for system and debug logs as well.

2) Practise hardening the system. In some sort it's space reclamation. There is a world of useful sources - see here, here and here.
    Improve your builder system. Make choices - ci/cd of 3rd party tools like gparted.
    Check latest security advisories  (here).

3) From time to time, audit may be key, and openness to experience.
