The query was successful. I believe ephemeral ports are picked dynamically, so perhaps if I knew all the MySQL clustering related processes that would be running, I can figure out every port that they are So you need to start ndb(mt)d on *both* node01 and node02, let them complete startup, and *then* if you want to only test ndb(mt)d on node01, you can stop ndb(mt)d on It can be that you have messed up thendb-connectstringin the my.cnf of that SQL node. news
