Mongo異常

我最近在我的電腦上有一些存儲問題，所以我更改了mongo.conf文件以減小日誌的大小。這些都是我放了行。Mongo異常

mmapv1: 
    smallFiles: true

然而，每次當我嘗試有了新的變化，我得到這個錯誤（不只是正常工作變動）運行蒙戈。你能告訴我有什麼問題嗎？

2016-02-11T22:32:14.002+0000 I FTDC [ftdc] Unclean full-time diagnostic data capture shutdown detected, found interim file, some metrics may have been lost. OK

我會嘗試刪除該目錄/data/db/diagnostic.data。

您也可以通過使用選項開始蒙戈禁用診斷數據收集：

setParameter: 
    diagnosticDataCollectionEnabled: false

你碰巧知道我是否刪除該目錄究竟發生了什麼？安裝時我不認爲我檢查了發送診斷。 –

如果您刪除該目錄，它將被重新創建。我建議您只在服務器停止時刪除該目錄。診斷數據收集默認啓用。它不會在任何地方「發送」，它只在本地收集。 – helmy

爲了澄清，'diagnostics.data'目錄本質上包含了一個定期的'db.serverStatus（）'輸出記錄，並且它不會被髮送到任何地方。如果您與MongoDB有支持協議，可能會要求您上傳此目錄的內容以獲得支持/疑難解答。 –

我有同樣的問題後，當HD是溢滿高達100％的MongoDB失敗。下面是日誌：

我kill -ed的mongod和清除診斷文件夾的內容：

> rm -f /var/lib/mongo/diagnostic.data/*

和蒙戈沒問題。

如果您使用nodejs，請嘗試禁用/刪除服務器代碼中的調試模式。

步驟：

rm -rf /{your_db_name}/diagnostic.data/
刪除或註釋掉mongoose.set('debug', true);
重啓蒙戈節點服務器
