Question

How do I know if my Ubuntu droplet is using the XFS filesystem?

I recently set up the one-click MongoDB 4.0.2 droplet on Ubuntu 18.04. When I enter the MongoDB shell I get the startup warning:

** WARNING: Using the XFS filesystem is strongly recommended with the WiredTiger storage engine

I have three questions:

  1. How do I know if I’m using the XFS filesystem?
  2. If I’m not using it, how do I switch to it?
  3. If I don’t use XFS, will MongoDB still function properly?

Greetings!

Great question. By default our droplets use ext4, and you can confirm this with the following command:

df -Th

I found an article that suggests a path for converting the filesystem:

I cannot guarantee that using alternate file systems will not interfere with certain functions of our cloud panel.
