Troubleshooting

Effective troubleshooting begins with understanding the current state of your MooseFS cluster. In the Observability chapter, you will find a detailed health checklist that outlines the recommended steps for verifying cluster correctness. We suggest reviewing your cluster using this checklist first; the results should help reveal any irregularities or potential issues.

This chapter explains how to address the most common problems that may surface during such a review. In addition to the guidance provided here, we also recommend consulting the Technical Insights and Observability chapters for deeper background information and best practices.
