Troubleshoot Docker, Fabric Manager, and Base Command Manager — Quick Reference

This quick reference guide provides essential facts and troubleshooting steps for Docker, Fabric Manager, and Base Command Manager within NVIDIA AI infrastructure, tailored for the NVIDIA-Certified Professional: AI Operations exam.

Docker Troubleshooting

• Check Docker service status: Use systemctl status docker or docker info to verify if Docker daemon is running properly.
• Inspect container logs: Use docker logs CONTAINER_ID to identify runtime errors or issues inside containers.
• Verify network connectivity: Confirm container network settings and connectivity with docker network ls and docker network inspect NETWORK_NAME.
• Resource constraints: Check if containers have sufficient CPU, memory, and GPU resources allocated; use docker stats for live metrics.
• Image and volume issues: Ensure container images are up to date and volumes are properly mounted; use docker images and docker volume ls.

Fabric Manager Troubleshooting

• Service status: Confirm Fabric Manager daemon is active with systemctl status nvidia-fabricmanager.
• Compatibility: Verify Fabric Manager version matches the installed NVIDIA driver version.
• Logs: Review Fabric Manager logs typically found in /var/log/nvidia-fabricmanager.log for errors or warnings.
• Hardware detection: Use nvidia-smi to confirm fabric connectivity and detect any link errors.
• Restart service: Restart Fabric Manager if issues persist using sudo systemctl restart nvidia-fabricmanager.

Base Command Manager Troubleshooting

• Verify service status: Check Base Command Manager with systemctl status base-command-manager or equivalent command.
• Authentication and permissions: Ensure correct user permissions and authentication tokens are configured.
• Connectivity: Confirm network access to Base Command Manager APIs and endpoints.
• Logs and errors: Inspect logs located in the Base Command Manager installation directory for detailed error messages.
• Restart and update: Restart the service and apply updates to resolve known bugs or compatibility issues.

Use this cheat sheet as a rapid diagnostic tool to identify and resolve common issues with Docker, Fabric Manager, and Base Command Manager in NVIDIA AI environments.
