Highly available NFS Share

A NFS share can be created on different volume types. This example shows how to create a NFS share on an arbiter volume.

- name: Setup NFS Ganesha
  hosts: servers
  remote_user: root
  gather_facts: false

  vars:
    gluster_features_ganesha_masternode: "{{ groups['servers'][0] }}"
    gluster_features_ganesha_clusternodes: "{{ groups['servers'] }}"

    # This has to be hostnames
    gluster_features_ganesha_haname: ganesha-ha-13-apr
    gluster_features_ganesha_volume: 'ganeshavol'
    gluster_features_ganesha_hostnames: "server1,server2,server3"
    gluster_features_ganesha_viplist: 10.70.44.121,10.70.44.122

    # Variables for backendsetup
    gluster_infra_stripe_unit_size: 128
    gluster_infra_pvs: /dev/vdb,/dev/vdc
    # Create a thin volume
    gluster_infra_lv_logicalvols:
       - { lvname: 'glusterstore_thinlv', lvsize: '500G' }
    gluster_infra_mount_devices:
       - { path: '/storage/ganesha',   lv: glusterstore_thinlv }

    # GlusterFS volume
    gluster_cluster_volume: 'ganeshavol'
    gluster_cluster_replica_count: 3
    gluster_cluster_arbiter_count: 1
    gluster_cluster_bricks: '/storage/ganesha/ganeshavol'
    gluster_cluster_hosts: "{{ groups['servers'] }}"
    gluster_cluster_force: 'yes'
  roles:
     - gluster.infra
     - gluster.cluster
     - gluster.features

The above playbook makes use of three roles: infra, cluster, and features for setting up backend, creating volume, and setting up NFS Ganesha respectively.

See gluster.cluster for setting up different types of volumes. And gluster.features for different variables and documentation on NFS Ganesha.
