Symptom & Impact

MySQL fails to start, causing database-backed applications to become unavailable.

Environment & Reproduction

Can occur after abrupt shutdowns, storage faults, or file corruption in InnoDB tablespaces.

Root Cause Analysis

InnoDB metadata or tablespace pages are corrupted and crash recovery cannot complete.

Quick Triage

Capture MySQL error log, confirm disk health, and assess recent unclean shutdown events.

Step-by-Step Diagnosis

Run table integrity checks and inspect InnoDB recovery traces to scope data impact.

Solution – Primary Fix

Use controlled recovery mode, export recoverable data, repair or rebuild affected tablespaces.

Solution – Alternative Approaches

Restore from backups or replicate from healthy node for rapid service restoration.

Verification & Acceptance Criteria

MySQL starts cleanly, integrity checks pass, and application queries complete successfully.

Rollback Plan

Roll back to previous database snapshot if repair path increases data inconsistency.

Prevention & Hardening

Implement reliable backups, graceful shutdown controls, and storage health monitoring.

Related Errors & Cross-Refs

Related to table marked crashed and read-only filesystem database failures.
