Example Playbook

Creating a NFS Ganesha Cluster:

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

---
- name: Setting NFS Ganesha
  remote_user: root
  hosts: ganesha_nodes
  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.

Note:

If you are using GlusterFS 4.0 (glusterd2) ensure to install python-gluster-mgmt-client package on the remote master host.

Or create a directory glusterapilib on the remote host and copy the files volume.py, peer.py, common.py,init.py, excpetions.py under glusterapilib in a python searchable path.
