Highly available SMB share on replica 3 volume

An SMB share can be created on different volume types. This example shows how to create a highly available SMB share on a replica 3 volume.

---
- name: Setup CTDB backed by an arbitrated volume
  hosts: ctdb_hosts
  remote_user: root
  gather_facts: false

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

    gluster_features_ctdb_nodes: 192.168.1.1,192.168.2.5
    gluster_features_ctdb_publicaddr: '10.70.37.6/24 eth0,10.70.37.8/24 eth0'
    gluster_features_ctdb_volume: samba

    # GlusterFS volume
    gluster_cluster_volume: 'ctdb'
    gluster_cluster_replica_count: 3
    gluster_cluster_bricks: '/storage/ctdb/ctdbvol'
    gluster_cluster_hosts: "{{ groups['ctdb_hosts'] }}"
    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 highly available SMB share respectively.

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