Object Storage at Scale: Real-world Operational Insights from RGW Deployments

About

Operating Ceph RADOS Gateway (RGW) as a backend for sync & share services presents unique challenges that differ from typical S3 workloads. Drawing from hands-on experience supporting RGW deployments across diverse production environments, this presentation shares practical operational insights that service operators can immediately apply.

We examine the most common issues encountered in RGW deployments backing sync & share platforms: from bucket index sharding misconfiguration and multisite sync lag to performance bottlenecks during metadata-heavy operations typical of EFSS workloads. Each issue is presented with its symptoms, root cause analysis approach, and resolution pattern.

The presentation introduces a systematic troubleshooting framework developed through supporting multiple deployments, covering diagnostic tools (radosgw-admin, ceph health, log analysis), key metrics to monitor, and decision trees for common failure scenarios. We discuss preventive measures including capacity planning considerations, configuration best practices for sync & share workloads, and monitoring strategies that provide early warning of emerging issues. Attendees will leave with actionable knowledge to improve the reliability and performance of their RGW-backed storage infrastructure, whether they are planning a new deployment or operating an existing one.
