Symptom & Impact

Multiple services fail post-restore due to widespread permission denied errors under enforcing mode.

Environment & Reproduction

After filesystem restore to RHEL 7, systemctl units fail despite correct Unix ownership and modes.

Root Cause Analysis

Backup tool restored files without original SELinux contexts, causing policy mismatches at runtime.

Quick Triage

Check getenforce and review AVC denials in journalctl to confirm label integrity issue.

Step-by-Step Diagnosis

Sample critical paths with ls -Z and compare against expected context mappings from policy defaults.

Solution – Primary Fix

Create /.autorelabel and reboot, or run restorecon targeted paths, then restart impacted services.

Solution – Alternative Approaches

Use semanage fcontext for custom paths and relabel incrementally to reduce maintenance impact.

Verification & Acceptance Criteria

Services start cleanly and AVC denials cease for previously affected components.

Rollback Plan

Restore from prior snapshot if relabel operation reveals deeper restore corruption.

Prevention & Hardening

Validate backup tooling preserves xattrs and include post-restore SELinux checks in runbooks.
