Symptom & Impact

journalctl returns File corrupted errors and new entries are not visible in queries.

Environment & Reproduction

Often follows abrupt power loss, full disk events, or filesystem damage on /var/log/journal.

Root Cause Analysis

Journal segments contain unrecoverable header errors and systemd-journald rotates or rejects writes.

Quick Triage

Run journalctl –verify and inspect systemctl status systemd-journald for repeated restarts.

Step-by-Step Diagnosis

Run: sudo journalctl –verify; sudo systemctl status systemd-journald; df -h /var.

Solution – Primary Fix

Move broken segments out of /var/log/journal, restart systemd-journald, then run journalctl –rotate.

Solution – Alternative Approaches

Forward journals to a remote systemd-journal-remote or rsyslog target to preserve history.

Verification & Acceptance Criteria

journalctl –verify reports PASS and new boot messages appear in current journal.

Rollback Plan

Restore /var/log/journal from backup if forensic timeline must be preserved.

Prevention & Hardening

Monitor disk space and configure SystemMaxUse to keep journal under safe limits.
