Can not start mongod

[Dung Tran]

Hello,

   I got this message when I started mongo db 

"[initandlisten] Detected data files in /data/db created by the 'wiredTiger' storage engine, so setting the active storage engine to 'wiredTiger'."  . Could you suggest on how could I resolve it?

I did google search and someone adviced that I should remove the mongod.pid and mongod.log and granted permission to mongod to the data folder. However , it is confusing because mongod was not running so mongod pid did not exist ; there fore the advise is not applicable.

 So please suggest a way on how to resoleve it.

Many thanks!

Hi,

“[initandlisten] Detected data files in /data/db created by the ‘wiredTiger’ storage engine, so setting the active storage engine to ‘wiredTiger’.”

This message is basically saying that you have an existing data in the /data/db folder, which was created by the WiredTiger storage engine. It is not an error message.

Could you post a more complete log showing the exact error that happened? Additionally, could you post:

• Your MongoDB and your OS version
• How did you install MongoDB
• What command line parameters you use to start the mongod process
• The content of any configuration files

Best regards,
Kevin
