how to add broker smoothly in a running dledger cluster?

[qq958905365]

hello guys, I want to add a broker to my running dledger cluster, and the cluster can't restart. I try to use mqadmin with updateBrokerConfig to update dLegerPeers, I can see dLegerPeers is already update to every broker, but the new broker can't work, the logs show me "WARN NettyServerPublicExecutor_1 - [BUG] [HandleVote] remoteId=n3 is an unknown member". could anybody help me?

currently, it is not able to add broker to a dledger group dynamically. You need to change the dledger configuration and restart all the brokers in the group.

@qq958905365 Could you describe the detailed use case? Why do need to add a broker to a running cluster? In fact, I used to think this op is not practical. It is better to fix the replica number during the deployment.
