Should hardlinks be working with this setup?

Issue: Hardlinks not working

Setup: Sonnar, Qbit and other Starrs running natively on MacOS. Downloads and media are on a Synology NAS connected via SMB.

File structure:
/Volumes/video/media/TV Shows (Sonarr root folder 1)

/Volumes/video/media/TV Documentaries (Sonarr root folder 2)

/Volumes/video/torrents/temp (incomplete downloads)

/Volumes/video/torrents/tv-sonarr (complete downloads)

MacOS User has read/write access to the /video volume. "Use Hardlinks instead of copy" is enabled under Sonarr Media Management Settings.

I don't have much experience with Terminal but was able to follow guides to check the inode numbers on files in the /Volumes/video/torrents/tv-sonarr folder and none of them show a value greater than 1, so hard links don't seem to be working.

Is this setup generally supposed to support hardlinks? Or are there changes to folder structure, or app settings that need to be made for this to work as intended?
