After much gnashing of teeth, I managed to get a three-server HA journal replication cluster going. Instructions for reproducing the environments are here: https://wikitech.wikimedia.org/wiki/Nova_Resource:Wikidata-query/Documentation

If you'd like to play with the instances, open up some tunnels and point your browser at localhost:808[1-3]:

ssh wdq-bg1 -L 8081:localhost:8080
ssh wdq-bg2 -L 8082:localhost:8080
ssh wdq-bg3 -L 8083:localhost:8080
