RH236 glusterfs存储配置
主机规划
其中前四个节点为配置glusterfs 分布式、复制、分布+复制、Geo异地同步等。其中前四个节点用于几种类型存储配置，第五台主机用作client访问、和Geo异常容灾模拟。需要注意的是，如下所有的配置中，我使用的都是IP，现网中建议使用主机名或域名的方式配置，这个IP发生变更时，无需在glusterfs中进行修改，只在dns中修改下指向IP即可。
| 主机名 | IP地址 | |

| node2 | server2-b.example.com | 172.25.2.11 |

| node4 | server2-d.example.com | 172.25.2.13 |
| node5 | server2-e.example.com | 172.25.2.14 |
