失敗した修復dbのクリーンアップ：パス：/ var / lib / docker / wesfgr / repair / _tmp_repairDatabase_0

Dockerコンテナー（単一ノード）でMMAPを使用してMongoDB 3.0.6を実行します。ファイルシステムがいっぱいで、他のパスで修復を行いました。

エラーはたくさんありますが、MongoDBは修復後に正常に起動しました。このエラーはどういう意味ですか？長期的に一貫性のないDBはありますか？

名前空間ファイルがまだ壊れているようですが、MMAPv1のデータベースのコレクションの最大数に達したときに同様のエラーが発生します。これを修正してより一貫した状態のデータベースを取得するには、新しいデータベースでコレクションを再作成してみてください。

認証を有効にしている場合は、管理データベースでこれを行う必要があります。ここでの実際のキーは、to:フィールドの新しいデータベースであることに注意してください。

use admin;
db.runCommand( { renameCollection: "db1.collection1", to: "db2.collection1" });

現在、データベース内のコレクションごとにこれを繰り返し、既存のファイルシステムにコレクションを再作成するための十分なスペースがあることを確認してください。それが完了したら、（念のため）バックアップして古いデータベースを削除することをお勧めします。
