Galera 10 кластер node отбрасывающие запросы
Мы сталкиваемся с ошибкой в Node 1 кластера 5- node. Запросы Node 1 кажутся успешными с точки зрения клиента, но не вставляются. Мы видим много ошибок автоинкрестности, хотя autoinc не должен участвовать в запросах обновления. Кроме того, это, по-видимому, вызывает проблемы с производительностью до тех пор, пока транзакция с более высоким приоритетом не начнет деактивировать автономный режим Node для выполнения транзакции. Ниже приведены некоторые записи в error.log с отладкой и прохождение установки. Мы не понимаем, как устранить неполадки. Единственный способ продолжить транзакции - это все клиенты, чтобы удалить и восстановить пул соединений.
Некоторые сведения о настройке:
- 5 Узлы, действующие как ведущие на их локальный сервер
- Все подключенные через WAN
- Node 1 также имеет внешние соединения SQL для доступа к веб-сайту.
- Каждый Node работает внутри докера на физической машине
Вот некоторые из ошибок:
