PhotoPrism Plugin for OpenMediaVault

Hello,

I am very new to OpenMediaVault. I am running OMV inside a Proxmox VM. I have passed a dedicated 2TB HDD to this VM for Sharing (over the network using SMB) purposes. Now my question is during the PhotoPrism configuration, I see that it's asking for 3 paths... 1)Images 2) Application Data, 3) Import

Question 1:

I would like all my images to be saved on the HDD that I have passed to the vm... How can I do that? Do I need to create a "Shared Folder" for that?

Question 2:

For Application Data, should I be using the same 2TB HDD? or should the application data will be on the same drive where VM is running (it's a 16gb drive). Ideally I would like to keep the application data on the VM (16gb drive) and Photos/Videos to be on the 2TB HDD

Question 3:

I already have Photos save on my 2TB HDD (not through photoprism but just by copying over SMB). Do I need to re-upload all the images again through PhotoPrism so it saves everything according to it's own naming convention/indexing etc? Or is there a way that PhotoPrism can take the all existing photos in my photos directory and import it... and than late I delete all the existing Photos (since it's now already imported by PhotoPrism)

Thanks.
