Hi I would like to know what the expected state after a successful master/slave failover is. The AMQ website seems to be inconsistent or at least not very accurate in this topic.
The general master/slave page with the different flavours listed, says for all types "Automatic recovery of old masters". http://activemq.apache.org/masterslave.html So I would expect that after a successful automatic failover, the former master is a slave and the former slave (one of them if multiple) is master. That means if other incidents occur, the automatic failover works again and again without any manual intervention. In contrast, the concrete page about shared-filesystem master/slave says "If the master ... it immediately shuts down". And later "after a restart of an old master". http://activemq.apache.org/shared-file-system-master-slave.html This gives me the impression that after a successful failover, the former master shuts down and the former slave becomes master. But I have to restart the former master manually. In other words: when I have two brokers, only one automatic failover can happen because after the first incident, I still have a master broker but no slaves left. Is my interpretation correct? And if yes, which one of the scenarios is correct? Or is the expected state depending on the concrete master/slave flavour? Thanks Stephan
