neo4j ha сбой кластера при запуске узла

Question

Я следовал этому руководству https://neo4j.com/docs/operations-manual/current/tutorial/highly-available-cluster/ чтобы установить кластер с 3 узлами на 3 разных виртуальных машинах на vsphere, и я испытываю некоторые проблема, когда дело доходит до запуска узла. (./bin/neo4j начало) Я проверяю журнал, и я получил что-то вроде этого

Я не понимаю, может кто-нибудь рассказать мне больше об этом. Как вы можете видеть, я работаю с Neo4j 3.2.9, и он работает нормально, когда я запускаю его в автономном режиме на каждой машине.

Answer 1

"Запись транзакций в базу данных отключена" МОЖЕТ означать, что МАСТЕР не может быть выбран. Может ли каждый экземпляр достичь других? Отличаются ли идентификаторы (в neo4j.conf)?
