Thanks for your feedback. I’d suggest starting the analysis to identify the type of most storage being consumed. Maybe CI/CD job artifacts are kept forever and need an expiration configuration [0], or container images in the registry would need cleanup policies [1]. The documentation linked in the FAQ provides more analysis and guides to help. [2]
If you need additional help with analyzing the storage usage, please contact the GitLab support team. You can also post cleanup questions on our community forum. [3]
