[17.03] Error mounting NFS volume when creating service: read-only file system

Docker Engine Swarm

Hello,

I’m getting an error I don’t understand when trying to create a service and mounting
an NFS volume.

$ docker service create --mount 'type=volume,target=/mnt,volume-driver=local,volume-opt=type=nfs,volume-opt=device=10.30.216.171:/shares/sw,"volume-opt=o=addr=10.30.216.171,ro"' --name fedora1 fedora /bin/bash

The volume it is referring to doesn’t exist either, so I can’t inspect it.
Any ideas?
