How to check if hardlinks are working

You've followed the guide step by step but still want to check if hardlinks are working, or someone on the Sonarr/Radarr support team asked you to check if your files are hardlinked?

You can use 2 options to check if you got working hardlinks.

Both ways requires you to login to your terminal with PuTTY or similar software.


Method 1: Using ls

This is the easiest to check in my opinion.

In your terminal cd to your download location and run ls-al or type ls -al /path/to/your/download/location/

You will get a listing of all your files and on the left side you will see a couple of numbers, every file with a number above 1 are hardlinks.

Hardlinks check ls -al

  • Red rectangle - Not Hardlinked
  • Green rectangle - Hardlinks
  • Blue rectangle - Folders/Directories you will need to go in to them to check if the files are hardlinked.

Method 2: Using stat

This way requires a bit more work.

  • On the terminal type: stat /path/to/your/download/location/file.mkv

  • On the terminal type: stat /path/to/your/media/location/file.mkv

You will get 2 results you can use to compare several things.

Hardlinks check stat

  1. Links: Everything above 1 means it's a hardlink
  2. Inode: if the numbers match you know the files are hardlinked
