蒙古异常 [英] Mongo Exception

问题描述

我最近在我的电脑上有一些存储问题，所以我改变了mongo.conf文件以减少日志的大小。这些是我输入的行。

  mmapv1：
 smallFiles：true 
  

然而，每次当我尝试运行mongo与新的更改，我得到这个错误（没有改变它的工作正常）。你能告诉我有什么问题吗？

解决方案

我会尝试删除目录 /data/db/diagnostic.data 。

您还可以通过启动mongo来禁用诊断数据收集选项：

  setParameter：
 diagnosticDataCollectionEnabled：false 
  

I recently had some storage issues on my PC so I changed the mongo.conf file to reduce the size of the journal. These are the lines which I put in.

mmapv1:
    smallFiles: true

However, every time when I try to run mongo with the new changes I get this error(without the change it works just fine). Can you tell me what's the problem?

I would try deleting the directory /data/db/diagnostic.data.

You can also disable the diagnostic data collection by starting mongo with the option:

setParameter:
    diagnosticDataCollectionEnabled: false
