Symptom & Impact

Mount fails with `XFS log corruption` after an unexpected power loss.

Environment & Reproduction

Common on bare metal hosts without UPS or filesystem barriers disabled.

Root Cause Analysis

Unflushed journal entries are inconsistent with on-disk metadata.

Quick Triage

Boot rescue media and run `xfs_repair -n ` to dry-run inspect.

Step-by-Step Diagnosis

Identify corrupted inodes and assess scope of repair.

Solution – Primary Fix

Repair the filesystem with `xfs_repair ` after unmounting and creating an image backup.

Solution – Alternative Approaches

Restore from snapshot or backup if repair leaves significant data loss.

Verification & Acceptance Criteria

Filesystem mounts cleanly and `xfs_info` shows healthy state.

Rollback Plan

Restore from backup if `xfs_repair` lost critical metadata.

Prevention & Hardening

Enable write barriers and provision UPS for production storage hosts.

Related Errors & Cross-Refs

Linked to dm-cache failures and disk controller battery issues.
