环境：
VMWARE做的两台虚拟机 网卡类型选择的是HOST ONLY
用ocfs2console工具，将node1 的 cluser.conf 信息可以同步到node2的

[root@node1 /]# cat /etc/ocfs2/cluster.conf
node:
        ip_port = 7777
        ip_address = 192.26.26.10
        number = 0
        name = node1
        cluster = ocfs2

node:
        ip_port = 7777
        ip_address = 192.26.26.20
        number = 1
        name = node2
        cluster = ocfs2

cluster:
        node_count = 2
        name = ocfs2
