Example Playbook

安装集群
- hosts: node1 node2 node3
  vars:
    - ipnames:
        '192.168.77.133': 'data-node1'
        '192.168.77.134': 'data-node2'
        '192.168.77.135': 'data-node3'
  roles:
   -  gluster
   
安装集群, 自定义副本
- hosts: node1 node2 node3
  vars:
    - ipnames:
        '192.168.77.133': 'data-node1'
        '192.168.77.134': 'data-node2'
        '192.168.77.135': 'data-node3'
    - gluster_volume_brick: '/export/sdb1/brick'
    - gluster_volume_create: >
        gluster volume create replvol repl 2 data-node1:/export/sdb1/brick data-node2:/export/sdb1/brick
    - gluster_volume_start: >
        gluster volume start replvol
  roles:
   -  gluster
   
客户端挂载
- hosts: node4
  vars:
    - ipnames:
        '192.168.77.133': 'data-node1'
        '192.168.77.134': 'data-node2'
