Step by step

On Unraid

Enable NFS

Go to Settings > Network Services > NFS

Enable NFS

I'm just going to create a share that stays on the cache where files don't get moved to the array.

Set the NFS settings. The IP address is the address of the Proxmox node. RW will allow PVE to view this share and read/write to it.

On Proxmox

I'm going to try and run an LXC with NFS as the volume

Configure NFS Storage

Go to Datacenter > Storage > NFS

Set the ID to whatever you want. Enter the the IP of the Unraid server. After doing so, we should be able to see the path of the share we created and configured for access earlier.

Not sure what content is for but i selected Disk Image and container.

Creating an LXC with NFS storage

Create a standard LXC. In this case im just creating a debian LXC.

Click next for the next few pages. Then create.

Success. Test that we can run it.

On Unraid, if we check the share we can see there is a folder being created by the LXC id.
