This 1 Command Freed 2.6GB on My Linux Server

Learn how to clean systemd journal logs & free disk space on Linux Systemd journal logs are useful for troubleshooting. But over time, they can quietly consume gigabytes of disk space especially on servers. In this video, I show you how to: • Check journal log disk usage • Delete old logs safely • Limit logs by size • Restrict the number of log files • Make log limits permanent • Prevent your server from running out of space This works on Ubuntu, Debian, Fedora, Arch, and most modern Linux distributions using systemd. 📌 1️⃣ Check Current Journal Disk Usage journalctl --disk-usage This shows how much space systemd journal logs are currently using. 📌 2️⃣ Delete Logs Older Than X Days To remove logs older than 14 days: sudo journalctl --vacuum-time=14d You can change 14d to: 7d (7 days) 30d (30 days) 2m (2 months) This removes archived logs older than the specified time. 📌 3️⃣ Limit Journal Logs by Total Size Limit total size to 500MB (example): sudo journalctl --vacuum-size=500M This deletes older logs until total journal usage is below 500MB. 📌 4️⃣ Make Log Limits Permanent (Recommended for Servers) Temporary cleanup is not enough. Logs will grow again. Edit the journald configuration file: sudo nano /etc/systemd/journald.conf If it's not here, check /usr/lib/systemd directory. Before editing, create a backup: sudo cp /etc/systemd/journald.conf /etc/systemd/journald.conf.bak Now find and modify (or uncomment) these parameters: SystemMaxUse=500M SystemMaxFileSize=72M SystemMaxFiles=10 What these do: SystemMaxUse → Maximum total disk space journal logs can use SystemMaxFileSize → Maximum size per log file SystemMaxFiles → Maximum number of log files retained Adjust these values based on your server storage. 📌 5️⃣ Restart journald After saving the file: sudo systemctl restart systemd-journald Now your system automatically enforces log limits. No more manual cleanup. Enjoy more disk space on your Linux system :)
