Symptom & Impact

/var/log/audit fills until disk pressure triggers service failures.

Environment & Reproduction

Triggered when auditd rotation thresholds are misconfigured or external tooling removes log files.

Root Cause Analysis

max_log_file_action set to keep_logs and disk usage exceeds threshold.

Quick Triage

Check `auditctl -s` and `/etc/audit/auditd.conf`.

Step-by-Step Diagnosis

Identify current log size and rotation settings.

Solution – Primary Fix

Tune `max_log_file`, `num_logs`, and `disk_full_action` in auditd.conf and restart auditd.

Solution – Alternative Approaches

Forward audit data via audisp to a remote collector.

Verification & Acceptance Criteria

/var/log/audit stays within bounds and `aureport` continues to return data.

Rollback Plan

Restore prior auditd.conf if audit retention drops below compliance threshold.

Prevention & Hardening

Monitor audit disk usage and tie thresholds to alerting.

Related Errors & Cross-Refs

Linked to journald growth and SIEM forwarding failures.
