How do I figure out about Data directory /data/db not found., terminating

Answer 1

I ran into this same issue a few days ago. I am using Mac OS. Apparently, there was a permission problem with having my data directory in the root of my home folder. So what i did was i just created a directory in a folder in a location where i definitely have permissions and then ran mongo db with the the --dbpath option set to that location. for example:

mongod --dbpath ~/documents/data/db

Hope this helps :D

Answer 2

The problem is that by default, Mongo points to that /data/db folder, and it either forgets to create or set ownership of it on installation.

sudo mkdir -p /data/db/

And then, we'll set the ownership of the folder to the user that's going to start the mongod service. Since I only use if for local development in my computer, I set myself as the owner:

sudo chown `id -u` /data/db

Now, just running mongod should do the job. Hope that helps you!

Answer 3

Just create a new folder in the data directory (the disk which was given in the error - for me, suggested to create these folders on the E disk). First create data the create db folser in data. Then start mongod again.
