**Issue Evaluation**
Category: `question` | Status: **Needs Info**
The title contains an error message (`Can't modify topic or subscription group from slave broker`), but the issue body only has the template text without any details filled in.
This error typically occurs when a write operation (create/update topic or subscription group) is sent to a slave broker instead of the master. This is expected behavior in RocketMQ — write operations must go through the master broker.
To help diagnose your specific case, please provide:
- [ ] RocketMQ version
- [ ] Deployment mode (DLedger / Controller / master-slave)
- [ ] The exact command or API call that triggered this error
- [ ] Whether you are using `mqadmin` or a custom client
- [ ] Broker configuration (`brokerRole` setting)
> **Note:** If you are using RocketMQ 5.x, consider filing issues against [apache/rocketmq](https://github.com/apache/rocketmq) instead of this externals repository.

**Issue Evaluation**
Category: `type/question`
This error occurs when you try to modify topics or subscription groups on a slave (read-only) broker. All write operations must be executed against the master broker. Ensure your `mqadmin` command targets the master broker's NameServer address, not a slave.
