Mongosが起動してエラーをスローしていないため、分散ロックピンガーでpingが失敗しました。 MongoDB 3.4.3の問題

Question

設定サーバーのレプリカセットへの接続に問題があり、Mongosが多くのエラーを投げています。 Mongodbのバージョンは3.4.3です。私はAmazon LinuxとUbuntu 14.04で同じ問題に直面しています。 この問題は、スタンドアロンのMongoDB設定サーバーでも発生します。

エラーは以下のとおりです。

すべてのヘルプは非常に高く評価されます。以下のconfigサーバのいずれかの設定がある

さて、問題は設定していました。設定サーバーに書かれている懸念事項「過半数」の書き込みがありました。そして、私は、 "最適化"するために、設定サーバー上のジャーナルを無効にしました。
