If you’re wondering why hard links aren’t working or why a simple move is taking far longer than it should.
Here we will try to explains it.
The paths you use on the inside matter. Because of how Docker’s volumes work, passing in two or three volumes such as the commonly suggested `/tv`, `/movies` and `/downloads` makes them look like two or three file systems, even if they aren’t. This means hard links won’t work and instead of an instant move, a slower and more I/O intensive copy + delete is used.
So you want one of the following ?
- Instant moves (Atomic-Moves) during import of the *arr (useful when using Usenet)?
- You don't want to use twice the storage when using torrents. (hardlinks)?
- Short answer is "having a file in multiple folders" without using up your storage, [Long Answer](https://medium.com/@krisbredemeier/the-difference-between-hard-links-and-soft-or-symbolic-links-780149244f7d){:target="_blank"}.
## Unraid - How To Set Up Hardlinks and Atomic-Moves
!!! note
The first thing you need to do is forget the suggested paths from the Spaceinvader One YouTube Tutorials,
And don't use the predefined paths from the unraid templates.
(Spaceinvader One YouTube guides are great to learn how to start with unraid or how to setup certain applications, and yes I did and still do use them. Probably the main reason why he's using those path is because they are predefined in the template)
!!! attention
To get Hardlinks and Atomic-Moves working with Unraid you will need to make use of **ONE** share with subfolders.
### Create the main share
For this example I'm using my own setup and preferred share `data`.
go to your dashboard and on the top select `shares` select `add share` .
1. if you got a cache drive and want to make use of it put it on `Yes` or keep it disabled (Hardlinks will stay in tact if you're using the cache)
1. click on `ADD SHARE`
!!! note
Keep in mind regarding the use of the Cache drive, The mover can't move files that are in use, like when `seeding` with torrents. You will need to shutdown your client or stop/pause the torrents so the mover can move them to your Array.
With Usenet you won't have any issues.
### Folder Structure
On the host (Unraid) you will need to add `/mnt/user` before it.
The `data` folder has sub-folders for `torrents` and `usenet` and each of these have sub-folders for `tv`, `movie` and `music` downloads to keep things neat. The `media` folder has nicely named `TV`, `Movies` and `Music` sub-folders, this is your library and what you’d pass to Plex, Emby or JellyFin.
These subfolders you need to create your self, you can use krusader or winscp to create them or any other way you prefer.
```none
data
├── torrents
│ ├── movies
│ ├── music
│ └── tv
├── usenet
│ ├── movies
│ ├── music
│ └── tv
└── media
├── movies
├── music
└── tv
```
*I'm using lower case on all folder on purpose, being Linux is case sensitive.*
### Setting up the containers
After you created all the needed folders it's time to setup the paths in the docker containers.
Go to your dashboard and select your docker container you want to edit or if you're starting fresh add the docker containers you want to use or prefer.
Unraid makes it actually pretty clear what's the Host Path and what's the Container Path.
`Container Path:` => The path that will be used inside the container.
`Host Path`: => The path on your Unraid Server (The Host).
The reason why we use `/data/torrent` for the torrent client is because it only needs access to the torrent files. In the torrent software settings, you’ll need to reconfigure paths and you can sort into sub-folders like/data/torrents/{tv|movies|music}.
The reason why we use `/data/usenet` for the usenet client is because it only needs access to the usenet files. In the usenet software settings, you’ll need to reconfigure paths and you can sort into sub-folders like/data/usenet/{tv|movies|music}.
Sonarr, Radarr and Lidarr get's access to everything because the download folder(s) and media folder will look like and be one file system. Hard links will work and moves will be atomic, instead of copy + delete.
Plex, Emby, JellyFin and Bazarr only needs access to your media library, which can have any number of sub folders like Movies, Kids Movies, TV, Documentary TV and/or Music as sub folders.
