Symptom & Impact

Database service exits immediately after upgrade and dependent apps fail.

Environment & Reproduction

Required schema migration not applied, config incompatibility, or ownership mismatch.

Root Cause Analysis

Run service status and inspect daemon startup output in foreground mode.

Quick Triage

Stop writes, back up data directory, and apply vendor-recommended upgrade path.

Step-by-Step Diagnosis

Start daemon manually with verbose flags to capture the first fatal error.

Solution – Primary Fix

Check config file diffs and database logs for version-specific deprecation failures.

Solution – Alternative Approaches

Run migration utilities, adjust config syntax, and confirm correct data directory permissions.

Verification & Acceptance Criteria

Verify service uptime and successful read/write transactions from application health checks.

Rollback Plan

Stage upgrades with dry runs and validated rollback snapshots.

Prevention & Hardening

Reinstall prior package version and restore pre-upgrade dataset snapshot if needed.

Related Errors & Cross-Refs

Escalate for data corruption indicators or failed migration tooling.
