Rancher - NFS or convoy / nfs?

I have a question regarding rancher convoy-nfs.

What we have:

2 nodes (VM Ware using NetApp network storage) on two different machines
a NetApp NFS mountpoint (NFS service and mountpoint is provided by NetApp itself, no additional service needed)
What we want:

a network drive mapped into the filesystem of each node carrying the docker vm’s use data
As far as I understood, convoy-nfs does the nfs management inside of another docker instance, adding another layer of abstraction and overhead to it.

In this constellation, would you recommend convoy-nfs? does it make any sense using it here? Or is it smarter to have the nfs mounts done on each vm individually and then transparently mounted into the docker instance?
