I am actually trying the same with a filesystem attached running on shared disk attached to both master and slave. Both the instances have the shared disk mounted formated with ext4 with the data folder shared and added as volume at /data-volume/artemis/data. The broker and artemis.profile config settings point to this shared directory for journal, paging, bindings and large-messages. I am not seeing the slave getting active when master is shutdown. Can someone share some insight?
