的MongoDB服務失敗後DB移動

Question

我的MongoDB安裝在Amazon EC2上開始跑出來的磁盤空間，所以我創建了一個新的EBS卷，完全關閉MongoDB的服務，複製數據庫文件到新的卷，在重新安裝相同的位置，以前的分區，並試圖重新啓動該服務，但我得到這個錯誤：

目錄對於MongoDB的用戶相應的權限。任何人都可以闡明爲什麼這不是開始？我可以使用配置

我應該指出，這樣做的工作手動啓動爲根：

$ sudo su mongodb 
$ mongod --config /etc/mongodb.conf & 

而且我使用的MongoDB 2.0.5從10根Apt庫。

Answer 1

「」 「 目錄對於MongoDB的用戶相應的權限。 」「」

顯然你的假設是錯誤的。我們是否應該相信你的假設或明確的錯誤信息？ 想想吧！

Answer 2

問題是由不足夠的權限對​​MongoDB的固定的權限應該做的伎倆後user.Restarting MongoDB的服務造成的。
