Error on startup for mongodb server

Question

totally new to mongodb. I'm trying to install locomotive CMS on my server, which is cool, but I've always used SQL/MySQL so mongo is totally new to me.

I installed all the needed mongodb modules, but when I run: sudo service mongod start I get an error code. When I look in the logs for the error, here is what is output:

Also, I run: sudo service mongod status and the output is mongod is stopped so I know it's not running.

Following the stack, it looks like the error has something to do with insufficient space, but my server has 15gb free and im running sudo, so i know it's not a permission error....how can I allocate more space...or better yet, what should i allocate more space to?

Any help is appreciated.

Answer 1

Add smallfiles = true to "/etc/mongodb.conf".

Now try to start the service, I assume this should fix the issue!!

Set to true to modify MongoDB to use a smaller default data file size. Specifically, smallfiles reduces the initial size for data files and limits them to 512 megabytes. The smallfiles setting also reduces the size of each journal files from 1 gigabyte to 128 megabytes.
