Description

With live-only ha policy, two brokers can be started at the same time even if they are using the same data store.

Data store should be exclusive to each broker, otherwise the data will get messed up.

This can be fixed using the shared store live activation, namely using the FileNodeManager to get exclusive lock before starting/init the broker.
