У мене налаштування з 2-х фрагментів, з 2-ма серверами реплік та 3-ма серверами конфігурації та 2 монгоми. У мене є такі проблеми:
1) сервери mongo config не синхронізовані:
Aug 14 09:46:48 server mongos.27017[10143]: Sun Aug 11 09:46:48.987 [CheckConfigServers] ERROR: config servers not in sync! config servers mongocfg1.testing.com:27000 and mongocfg3.testing.com:27000 differ#012chunks: "d2c08c5f1ee6048e5f6fab30e37a70f0"#011chunks: "7e643e9402ba90567ddc9388c2abdb8a"#012databases: "6f35ec52b536eee608d5bc706a72ec1e"#011databases: "6f35ec52b536eee608d5bc706a72ec1e"
2) Я використовую цей документ для синхронізації серверів: http://docs.mongodb.org/manual/tutorial/replace-config-server/ 3) Після синхронізації я перезавантажую один сервер mongos і бачу це в журналах:

Перші монгоси також мають цю помилку "попередження: помилка завантаження початкової інформації конфігурації бази даних :: викликана :: Не вдалося завантажити дійсну конфігурацію для collection.documents після 3 спроб. Будь ласка, спробуйте ще раз."
але працюйте поки що.
Другі монги після перезавантаження не працюють;

Які наступні кроки для відновлення серверів конфігурації?
Всі поради вітаються.
