[GitHub] [rocketmq] qq958905365 opened a new issue #3840: how to add broker smoothly in a running dledger cluster?
qq958905365 opened a new issue #3840:
URL: https://github.com/apache/rocketmq/issues/3840
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.
