Portainer: Invalid Argument Error when Deploying Portainer with Volume to Persist Data (Docker Swarm)

Description

Hello,

I am currently attempting to deploy Portainer as part of a swarm on a local Vagrant environment (3 Ubuntu 16.04 machines, one manager and two workers). When I specify a volume to persist Portainer data the service continuously fails with task: non-zero exit (1) and when I run docker service logs I see the following error: invalid argument. The section of the stack YAML file pertaining to Portainer is like so:

portainer:
    image: portainer/portainer:latest
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock
      - /volumes/monitor/portainer/data:/data
    deploy:
      placement:
        constraints:
          - node.role == manager
    networks:
      - monitor

It should also be noted that when I do not specify the volume for Portainer data the service runs with no issues at all.

Additional Info: The root of the portainer volume /volumes is within a shared folder on vagrant that has permissions set to 777 for both directory and file mode.

Any help anyone could give would be greatly appreciated. Thank you.

1. Start Vagrant Environment (I can provide more details here if needed)
