Hello, I am having the darnest time getting rancher-nfs working. The NFS share is off a FreeNAS system and while the following test docker-compose actually works with it:
docker-compose.yml
version: ‘2’
volumes:
test_volume:
external: true
driver: rancher-nfs
services:
test:
image: ubuntu
volumes:
- test_volume:/data
tty: true
command:
- bash
However the Docker gives me this (apparently common) chown error. Is there a known issue that would cause this? I am able to mount the NFS location from all hosts containing these containers (even added nfs-utils to the container itself just incase). I dont believe this to be a permissions issue since I am able to test functionality using the ubuntu image above - just lost on getting this going 
Error:
(Failed to allocate instance [container:1i299]: Bad instance [container:1i299] in state [error]: Error response from daemon: chown /var/lib/rancher/volumes/rancher-nfs/cacti_tmp: invalid argument)

cacti_tmp:

This is using Centos7 has the agent nodes and Rancher 1.5.3, any help would be greatly appreciated.
