Symptom & Impact

System logs XFS metadata warnings, mounts read-only, or application writes fail after abrupt power/event loss.

Environment & Reproduction

RHEL 8 servers using XFS on local or SAN-backed block storage.

Root Cause Analysis

Unclean shutdown or underlying storage path instability leaves filesystem metadata in inconsistent state.

Quick Triage

Check dmesg and journalctl -k for XFS errors; verify storage health with smartctl or array diagnostics.

Step-by-Step Diagnosis

Capture exact XFS error signatures and affected mount points before attempting repair.

Solution – Primary Fix

Unmount affected filesystem, run xfs_repair in maintenance window, then remount and restore service operations.

Solution – Alternative Approaches

Confirm clean mount, no recurring kernel XFS warnings, and successful application write/read operations.

Verification & Acceptance Criteria

If repair risk is high, restore from snapshots/backups and isolate failing storage path.

Rollback Plan

Use reliable power protection, monitor storage path health, and validate graceful shutdown procedures.

Prevention & Hardening

Preserve forensic evidence of storage events for root-cause and audit investigations.

Related Errors & Cross-Refs

Automate kernel log scanning for XFS error patterns and trigger incident workflow immediately.
