Describe the bug
Changing movie's root folder is unable to move the files between drives in mergerfs pool. If hardlink enabled in media management then nothing happens, if disabled then root gets changed in the database but the files aren't moved physically.

To Reproduce

create a mergerfs pool with 2 drives
create 1 -differently named- folder on both drives, like "movies" on A drive and "Movies" on B drive
add both to Radarr as root
add a movie to one of them and try to move it to the other and choose "yes, move the files" option

Expected behavior
A move should be move, not hardlinking and then delete the original.

Platform Information (please complete the following information):

Version 3.0.1.4263
Package Version 3.0.1.4263-ls4 by linuxserver.io
.NET Core Yes (3.1.10)

Need to know if this is reproducible on sonarr as well

either upstream issue or something radarr (netcore?) specific

@bakerboy448 I am using Sonarr 3.0.7.1477 (mono 6.8.0.105 on the TrueNAS-12.0-U8) and the "Move" operation works just fine. I had seen this report, but I did not have the "mergerfs" type config, Thanks for handling this.

I can confirm the same thing happens on Sonarr 4.2.4.6635 if mergerfs is used.

The primary development team is engaged in over five applications, including Lidarr, Prowlarr, Radarr, and Sonarr. Currently, there is approximately no active developers contributing to these projects, with none of the contributors working on them full-time. Additionally, all members involved, whether in development or support roles, are volunteers and do not receive compensation for their contributions. Each team member balances their commitments alongside full-time jobs, family responsibilities, and other personal obligations.

As a result, the list of tasks to be completed across these projects, along with the various backends and modules, is extensive, while the available time for addressing these tasks is limited.

Unfortunately a toxic community and abusive users drove away the active developer into burnout.

The community also does not appear to believe this is an "important bug" as no community member has took it upon themselves to implement a solution upstream into Sonarr and/or PR downstream. This is an issue specific to edge cases and unique niche setup with certain merge file systems / configurations.
