Mongo例外

标签： mongodb exception

我最近在PC上遇到了一些存储问题，因此我更改了mongo.conf文件以减小日志的大小。这些是我投入的。

mmapv1:
    smallFiles: true

但是，每次当我尝试使用新的更改运行mongo时，我都会收到此错误（没有更改它可以正常工作）。你能告诉我这是什么问题吗？

我会尝试删除目录/data/db/diagnostic.data。

您也可以通过以下选项启动mongo来禁用诊断数据集：

setParameter:
    diagnosticDataCollectionEnabled: false

MongoDb失败后，当HD达到100％时，我遇到了同样的问题。这是日志：

Shutting down the full-time diagnostic data capture subsystem.

我kill - 编辑了mongod并清除了诊断文件夹的内容：

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

mongo log重启后显示：

和mongo还可以。

答案 2 :(得分：1)

如果您使用的是nodejs，请尝试在服务器代码中禁用/删除调试模式。

步骤：

  1. rm -rf /{your_db_name}/diagnostic.data/
  2. 删除或评论mongoose.set('debug', true);
  3. 重新启动mongo和节点服务器
