Disaster recovery and data replication are critical for production Kubernetes workloads, yet implementing them for persistent storage remains challenging. This lightning talk demonstrates how RADOS namespace mirroring in Ceph RBD, orchestrated through Rook, enables seamless cross-namespace and cross-cluster block storage replication.

We'll explore:
- Quick overview of RBD mirroring architecture and RADOS namespaces
- Setting up namespace-based mirroring pools in Rook-managed Ceph clusters
- Configuring cross-namespace mirroring for multi-tenant isolation
- Demo: Automated failover scenarios and recovery workflows
- Performance considerations and best practices for production deployments

Attendees will leave with practical knowledge to implement robust disaster recovery strategies for their stateful Kubernetes applications, leveraging Rook's declarative approach to manage complex Ceph mirroring topologies. Perfect for platform engineers and SREs managing critical data workloads.
