Symptom & Impact

Systemd journal consumes excessive disk space under /var/log/journal.

Environment & Reproduction

Filesystem usage spikes and journalctl –disk-usage reports large values.

Root Cause Analysis

Check journald.conf limits and high-volume units with journalctl –since.

Quick Triage

No retention caps plus noisy services generating repetitive logs.

Step-by-Step Diagnosis

Set SystemMaxUse and RuntimeMaxUse, then vacuum old journals.

Solution – Primary Fix

Confirm new size policy and stable growth trend after restart.

Solution – Alternative Approaches

Tune service log levels and alert on journal growth.

Verification & Acceptance Criteria

Revert journald.conf changes if troubleshooting requires longer retention.

Rollback Plan

Template journald config and reload via systemctl restart systemd-journald.

Prevention & Hardening

journalctl –disk-usage; journalctl –vacuum-size=1G

Related Errors & Cross-Refs

Provide top noisy units and journald configuration.
