Symptom & Impact

Future yum operations fail with transaction test errors after a power loss during package upgrade.

Environment & Reproduction

RHEL 7 server loses power mid-update; next yum run detects incomplete rpmdb and dependency inconsistencies.

Root Cause Analysis

Interrupted writes leave package metadata inconsistent, causing rpmdb checks and dependency resolution to fail.

Quick Triage

Check yum history, run rpmdb verification, inspect systemctl and service health, and gather journalctl evidence.

Step-by-Step Diagnosis

Identify broken package set, inspect lock files, and review SELinux/firewalld side effects during outage recovery.

Solution – Primary Fix

Rebuild rpmdb as needed, complete pending package actions, clean yum caches, and rerun full update.

Solution – Alternative Approaches

Restore from snapshot, use yum history rollback, or re-provision node from golden image baseline.

Verification & Acceptance Criteria

yum check returns clean results, services run normally, and subsequent updates complete without transaction errors.

Rollback Plan

If repair introduces regressions, revert to snapshot or prior package state and restart affected services.

Prevention & Hardening

Use UPS protection, staged updates, and automated health checks to catch interruption risks before impact.

Related Errors & Cross-Refs

Related issues include rpmdb lock corruption, kernel partial updates, and firewalld service startup failures post-upgrade.
