How can I tell where mongoDB is storing data? (its not in the default /data/db!)

Question

My host came with a MongoDB instance and there is no /db directory so now I am wondering what I can do to find out where the data is actually being stored.

Answer 1

You can use the below-mentioned way to tell wg=here MongoDB is storing:-

By default, mongod sets the database location to /data/db/.

For checking by yourself you should run ps -xa | grep mongod and if you don't see a --dbpath which explicitly tells mongod to look at that parameter for the db location and you don't have a dbpath in your mongodb.conf, then the default location will be: /data/db/ and you should look there.

Answer 2

First, you have to see your configuration file:

$ grep dbpath /etc/mongodb.conf

Generally, your database files will be present on the list:

$ sudo lsof -p `ps aux | grep mongodb | head -n1 | tr -s ' ' | cut -d' ' -f 2` | grep REG

By default it gets stored at /var/lib/mongodb/* 

Note: There is a /var/lib/mongodb/mongod.lock file in MongoDB that basically holds the mongod PID.
