To test Raft cluster failover in RobustMQ, you can run a failover drill that simulates node removal, recovery, and leader election on a 3-node meta-service cluster. This verifies that the cluster maintains data consistency and membership after disruptions.

Verifying node recovery and snapshot replication in a RobustMQ Raft cluster involves running a dedicated failover drill. The drill tests whether snapshots are correctly replicated across nodes and if recovered nodes rejoin the cluster without data loss.

Yes, the RobustMQ Raft failover drill supports graceful shutdown testing to confirm that nodes can be shut down gracefully without data loss. It ensures the 3-node cluster maintains data consistency throughout the shutdown process.

This failover drill is specifically designed to verify the robustness of a 3-node Raft cluster in RobustMQ. Testing clusters with a different number of nodes is not covered by the current drill implementation.

Yes, you need the RobustMQ broker and its associated configuration files set up before running the drill. The skill requires this environment to simulate cluster startup, node removal, and leader election scenarios effectively.

Data consistency loss after a node failure indicates an issue with leader election or snapshot replication. Running a failover drill helps verify the cluster's leader election mechanism and snapshot replication to ensure data consistency is maintained.
