MongoDB : A Service Specific error occurred :100

Question

I have just installed "mongodb" on Windows, while starting it, the following error appears

A Service Specific error occurred :100

Any Suggestions?

Answer 1

Please try running the below commands as Administrator in the comment prompt.

1. mongod --repair

2. mongod --remove

then like @Yahya did, specify the log path,

3. mongod --install --logpath C:\data\db\log\mongo.log

4. net start mongodb

Hope it helps.

Answer 2

For me, somehow directories I have specified for db and log config file were not auto created.

dbpath=\data\db

logpath=\data\log\mongo.log

so I created them manually then ran the command again and service started.

I am using v3.4.9 om Windows 10

Answer 3

The reason for this error message is that you have another process already established. In my case it was the mongod.exe file I had opened in CMD, when I closed it and restarted the net start MongoDB command, it connected successfully. BTW i am using Windows 10 current build as of July 2017 with MongoDB 3.4
