Re: Artemis JDBC storage for HA- possible Split-brain?
Do you mean you would use jdbc storage and ha replicaiton? If so, the
split-brain issue are still there IMO since storage type is not related to
vote mechanism which checks whether node is alive.

Re: Artemis JDBC storage for HA- possible Split-brain?

Have you looked at the network health check
https://activemq.apache.org/components/artemis/documentation/latest/network-isolation.html
If you cannot add more nodes, but are getting split brain issues, this can help reduce issues.
Basically you set some remote network ping addresses (loadbalancer, firewall some core switch) ideally a couple of hops away, and should a node not be able to ping them, it will assumes it is the isolated node and will stop it from promoting itself.
