Symptom & Impact

Container workloads fail to start because docker service cannot initialize storage backend.

Environment & Reproduction

Occurs after kernel or filesystem changes incompatible with configured storage driver.

Root Cause Analysis

Current graphdriver configuration does not match host filesystem and kernel capabilities.

Quick Triage

Run systemctl status docker and review detailed daemon startup logs with journalctl -u docker.

Step-by-Step Diagnosis

Inspect /etc/sysconfig/docker-storage and filesystem mount options for overlay support.

Solution – Primary Fix

Set supported storage driver, clean stale metadata carefully, and restart docker service.

Solution – Alternative Approaches

Use devicemapper thin pool when overlay constraints cannot be met.

Verification & Acceptance Criteria

docker info reports healthy driver and containers start without storage errors.

Rollback Plan

Restore previous storage config and image metadata backup if workload startup regresses.

Prevention & Hardening

Validate storage driver compatibility before kernel upgrades and automate prechecks.

Related Errors & Cross-Refs

Error initializing graphdriver, invalid argument mounting overlay, daemon startup failed.
