I am facing an issue in Apache ActiveMQ Artemis where, when the master node goes down, the slave node becomes active as expected. However, when the master node is brought back online, it does not regain its active role.
Here’s a brief overview of my setup:
- Configuration: We are using a master-slave configuration in ActiveMQ Artemis.
- Mode: The nodes are set up in shared store mode with failover enabled.
- Logs: No specific errors are logged when the master node comes back online, but it doesn't transition back to the active state.
- Environment: This is running on Linux.
- Versions: I am using ActiveMQ Artemis 2.31.2.
I've checked the configuration, but I'm unable to resolve the issue. Could anyone suggest what could be going wrong or what steps I might be missing to ensure the master node becomes active again after it’s restarted?
