Mongo例外

Question

私は最近、自分のPC上にいくつかのストレージの問題があったので、mongo.confファイルを変更してジャーナルのサイズを小さくしました。これらは、しかし、私は（変更なしそれだけで正常に動作します）このエラーを取得し、新たな変更でモンゴを実行しようとするたびに、私は入れライン。

mmapv1: 
    smallFiles: true 

です。何が問題なのか教えていただけますか？

Answer 1

私はディレクトリ/data/db/diagnostic.dataを削除しようとするだろう。

ます。また、オプションでモンゴを開始することにより、診断データの収集を無効にすることができますHDは100％件まで縮充されたときのMongoDBが失敗した後

と診断フォルダの内容をクリア：ここにログがある

のmongoログの再起動が示した後：

とモンゴ大丈夫だった。

Answer 3

nodejsを使用している場合は、サーバーコードでデバッグモードを無効/削除してみてください。

ステップ：

1. rm -rf /{your_db_name}/diagnostic.data/
2. 削除またはmongoose.set('debug', true);
3. 再起動モンゴとノードサーバ
