Changing MongoDB data store directory

🏆 Changing MongoDB Data Store Directory: A Simple Guide for the Space-Strapped 🚀

Running out of space on your MongoDB data directory? Feeling stuck in a disk space black hole? Fear not, fellow explorer! In this guide, we will show you how to transfer your MongoDB data to a new disk without disturbing your existing installation. Let's blast off! 🚀

The Problem: Out of Space, New Disk Ready to Roll 😱

So, you've hit the limits of your current data store directory at /var/lib/mongodb/ and you just added a spacious new hard disk? Awesome move! But how do you make the switch without causing chaos? We've got your back! 🔌

The Solution: Data Transfer in 3 Simple Steps 🔄

Follow these three 🎯 steps to successfully transfer your MongoDB data to the new disk:

Step 1: Stop MongoDB ⛔

First things first, we need to put MongoDB into hibernation before we start shuffling data around. Open your command-line interface, tighten your grip, and run the following command:

sudo service mongod stop

Step 2: Move Data to the New Disk 📦

With MongoDB asleep, it's time to delicately transfer those precious data files. Execute the following script, making sure to substitute /new/data/directory 😎 with the path to your new, spacious disk:

sudo rsync -av /var/lib/mongodb/ /new/data/directory

Double-check that the data migration went smoothly by verifying that all data files have been successfully moved to the new disk.

Step 3: Update MongoDB Configuration ⚙️

We're almost there! Now, we need to inform MongoDB about its rocking new data store location. Open the MongoDB configuration file using your favorite text editor (let's say it's Vim for the sake of coolness):

sudo vim /etc/mongodb.conf

Within the configuration file, locate the line defining the dbPath parameter. Modify the path to the new data directory:

dbPath: /new/data/directory

Save and close the configuration file. MongoDB is now aware of its new home! 🏠

Take Control of Your MongoDB Galaxy 🌌

Congratulations, space commander! You have successfully transferred your MongoDB data store directory to a new disk without causing any damage to your existing installation. Now, you can fully enjoy the depths of space without worrying about disk space shortages. 🎉
