What does your configuration file say     grep dbpath  etc mongodb conf   If it is not correct  try this  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   It s  var lib mongodb   on my default installation  Ubuntu 11 04    Note that there is also a  var lib mongodb mongod lock file holding mongod PID for convenience  however it is located in the data directory - which we are looking for

mongod defaults the database location to  data db    If you run ps -xa   grep mongod and 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

If you could somehow locate mongod log and the do a grep over it  grep dbpath mongod log   The value for dbpath is the data location for mongodb    All the best

I find db serverCmdLineOpts   the most robust way to find actual path if you can connect to the server  The  parsed storage dbPath  contains the path your server is currently using and is available both when it s taken from the config or from the command line arguments    Also in my case it was important to make sure that the config value reflects the actual value  i e  config didn t change after the last restart   which isn t guaranteed by the solutions offered here   db serverCmdLineOpts     Example output          argv                  --             parsed               config      your-config            storage                   dbPath      your actual db path                  --                       ok    1 0

Actually  the default directory where the mongod instance stores its data is  data db on Linux and OS X   data db on Windows To check the same  you can look for dbPath settings in mongodb configuration file   On Linux  the location is   etc mongod conf  if you have used package manager to install MongoDB  Run the following command to check the specified directory  grep dbpath  etc mongodb conf   On Windows  the location is  lt install directory gt  bin mongod cfg  Open mongod cfg file and check for dbPath option  On macOS  the location is  usr local etc mongod conf when installing from MongoDB   s official Homebrew tap    The default mongod conf configuration file included with package manager installations uses the following platform-specific default values for storage dbPath   -------------------------- ----------------- ------------------------            Platform           Package Manager   Default storage dbPath    -------------------------- ----------------- ------------------------    RHEL   CentOS and Amazon   yum                var lib mongo             SUSE                       zypper             var lib mongo             Ubuntu and Debian          apt                var lib mongodb           macOS                      brew               usr local var mongodb    -------------------------- ----------------- ------------------------   The storage dbPath setting in the configuration file is available only for mongod  The Linux package init scripts do not expect storage dbPath to change from the defaults  If you use the Linux packages and change storage dbPath  you will have to use your own init scripts and disable the built-in scripts  Source

When you start it up it shows you   But I don t know if it is something you can do or not on your host   If you have access to the command line and can restart the service  you will get something like       2016-11-15T12 57 09 182-0500 I CONTROL   initandlisten   MongoDB starting   pid 16448 port 27017 dbpath C  data db

While this question is targeted for Linux Unix instances of Mongo  it s one of the first search results regardless of the operating system used  so for future Windows users that find this   If MongoDB is set up as a Windows Service in the default manner  you can usually find it by looking at the  Path to executable  entry in the MongoDB Service s Properties
