### Before Creating the Bug Report - [X] I found a bug, not just asking a question, which should be created in [GitHub Discussions](https://github.com/apache/rocketmq/discussions). - [X] I have searched the [GitHub Issues](https://github.com/apache/rocketmq/issues) and [GitHub Discussions](https://github.com/apache/rocketmq/discussions) of this repository and believe that this is not a duplicate. - [X] I have confirmed that this bug belongs to the current repository, not other repositories of RocketMQ. ### Runtime platform environment suse linux ### RocketMQ version 5.1.1 ### JDK Version 1.8 ### Describe the Bug The architecture consists of three data centers, three brokers, one master, and two slaves. Three controllers are also one for each data center (the same as the nameserver). Simulate the isolation of the broker master and one controller network from the brokers and controllers of the other two data centers. During network failures, it can be observed that two broker masters will appear, and when the network is restored, the original master will become a slave. However, messages sent to the original master during network failures will be lost. ### Steps to Reproduce 1,Simulate the isolation of the broker master and one controller network from the brokers and controllers of the other two data centers. 2,send message to the original master ### What Did You Expect to See? Sending a message to the original master that has been quarantined should result in an error ### What Did You See Instead? Sending a message to the original master that has been quarantined did not report an error ### Additional Context _No response_ -- This is an automated message from the Apache Git Service.
