Symptom & Impact

Filesystem mounts read-only or fails to mount, causing immediate service outage.

Environment & Reproduction

Observed after abrupt shutdowns on busy XFS-backed data volumes.

sudo journalctl -b -k | grep -i xfs

Root Cause Analysis

Interrupted writes leave inconsistent metadata structures requiring offline repair.

Quick Triage

Protect current state, stop writes, and verify whether logs can replay cleanly.

sudo systemctl isolate rescue.target

Step-by-Step Diagnosis

Unmount affected volume and run non-destructive checks before full repair.

sudo xfs_repair -n /dev/mapper/vg0-data

Solution – Primary Fix

Perform offline xfs_repair and remount with health verification.

sudo xfs_repair /dev/mapper/vg0-data && sudo mount /dev/mapper/vg0-data /data

Solution – Alternative Approaches

Restore from snapshot or backup if damage is extensive or repair is unsafe.

Verification & Acceptance Criteria

Volume mounts read-write and application integrity checks pass.

Rollback Plan

Unmount and revert to backup volume if post-repair validation fails.

Prevention & Hardening

Use power protection, write barriers, and tested backup strategy for critical XFS data.

Related Errors & Cross-Refs

Cross-check block-layer I/O errors and controller firmware issues.
