An example playbook to deploy NFS Ganesha. Note to gather_facts should be set to true.

---
- name: Setting NFS Ganesha
  remote_user: root
  hosts: nfs_ganesha
  gather_facts: false

  vars:
     # Setting up NFS Ganesha
     gluster_features_ganesha_haname: ganesha-ha
     gluster_features_ganesha_volume: nfs_ganesha
     gluster_features_ganesha_hostnames: "server1,server2,server3,server4"
     gluster_features_ganesha_viplist: 10.70.44.121,10.70.44.122,10.70.44.123,10.70.44.124

     gluster_features_ganesha_masternode: "{{ groups['ganesha_nodes'][0] }}"
     gluster_features_ganesha_clusternodes: "{{ groups['ganesha_nodes'] }}"

  roles:
     - gluster.features

The above playbook assumes that a volume named nfs_ganesha is created and running.
