问题
I am trying to take dump of my mongo DB. As i am using meteor so i used the meteor command for taking dump i.e:-
mongodump -h 127.0.0.1 --port 3001 -d meteor
I also try to save the dump in a different location i.e:-
mongodump -h 127.0.0.1 --port 3001 -d meteor --out /home/parveen/Desktop/
But both time it will create a directory with name meteor and that directory is blank. I am just wondering to know why this is happening because i tried the same command few months before that time i got the dump as expected. But now its not working, i guess that might be because of new meteor update.
would appreciate if anybody give me any answer or guess why is this happening.
Thanks

I get the answer why this is happening to me. Actually this issue is not related to meteor. This is because of mongod version that is not updated . Once i upgrade my mongod version to v3.2.0 and after that i hit the above given command for mongo dump . Its create a directory and not blank directory this time with theDB files.
For checking the monngod version simply type:-
mongod --version
For upgarde your version of Mongod just do following:-
sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv EA312927
udo apt-get update
sudo apt-get install -y mongodb-org=3.2.0 mongodb-org-server=3.2.0 mongodb-org-shell=3.2.0 mongodb-org-mongos=3.2.0 mongodb-org-tools=3.2.0
Hope it will help!
Thanks

First, you need to spin up meteor.
Then if you run
meteor mongo
you will get an output something like this:
MongoDB shell version: 2.2.1
connecting to: 127.0.0.1:3001/meteor
Meteor DB host is at 127.0.0.1 with a port of 3001. Exit the mongo shell and use mongo dump from your terminal.
mongo dump -h 127.0.0.1 --port 3001 -d meteor
Dumps will be located under the dumps folder in the folder you executed the above command.
You can import your DB back to meteor with
mongorestore -h 127.0.0.1 --port 3001 -d meteor dump/meteor
