Hi Newbie here.
I've set up Unraid on a purpose-built NAS as my QNAP was getting old and tired. I found most things very straightforward. I tested a couple of other NAS OS but decided on Unraid due to its easy learning curve.

I've set up my shares and can see them in the Unraid dashboard. When I install apps from Docker, they install perfectly and tell me where the data will be stored /mnt/usr/Media. This is very good, however... when I attempt to point the app to these folders, they just do not appear. I'm used to a dropdown or auto-complete when using QNAP.

It is very frustrating as I want to start populating my apps with data.
Apps used: Stash-S6 all the ARRs, Syncthing.

My question is, how do I determine the shares address, so I can enter it into these apps?

Apologies if this question is formatted incorrectly or vital information is missing. I'm a newbie

mnt/usr/Media

I assume this is a typo.

 

The user shares are /mnt/user

 

But, that part of the "mapping" is the host path. 

 

Within the container application you will find that data at the container path. 

 

For example, if you have a user share named Media, then its path is /mnt/user/Media.

 

But that is the host path. If the container maps that to /Media, then inside the container application, it would find the data at /Media.

 

https://docs.unraid.net/unraid-os/manual/docker-management/#volume-mappings

Further to this I have noticed that the mappings of the Docker container do not match the mappings from Stashapp.
My question is which mappings should I alter, container or app?

Your first screenshot shows you trying to access /mnt/user from the container application. That path is the host path to the user shares. The container has no direct access to host paths.

Your second screenshot shows the application trying to use paths /data/(VIDEOS) and /data/(PHOTOS).

Your third screenshot show you do actually have a container path /data, mapped to /mnt/user0/Media/Adult. Why do you want to user /mnt/user0? /mnt/user0 only includes those parts of the user shares that are on the array and excludes those parts of the user shares that are on any pools.

With that mapping, anything inside the container path /data would be at the host path /mnt/user0/Media/Adult. So, using the paths specified in your second screenshot, /data/(VIDEOS) is at the host path /mnt/user0/Media/Adult/(VIDEOS), and /data/(PHOTOS) is at the host path /mnt/user0/Media/Adult/(PHOTOS).

You have several other host paths specified in your third screenshot, but it isn't clear what if anything those correspond to as container paths.

Post docker run for that container.

This seems a little confused. Stashapp, the application, does not have "mappings" exactly. The container has mappings, that map container paths to host paths. The container paths are paths you want the application to use, and the mapped host paths correspond to the container paths.

What paths do you want the application to use? Those in your second screenshot labeled Library?
