我在 Centos7 中使用 Pacemaker + Corosync 使用以下命令创建集群：
pcs cluster auth pcmk01-cr pcmk02-cr -u hacluster -p passwd
pcs cluster setup --name my_cluster pcmk01-cr pcmk02-cr
[pcmk01]# pcs cluster start --all
[root@pcmk01 /]# pcs cluster cib clust_cfg
[pcmk01]# pcs -f clust_cfg property set stonith-enabled=false
[root@pcmk01 /]# pcs -f clust_cfg property set no-quorum-policy=ignore
[root@pcmk01 /]# pcs -f clust_cfg resource defaults resource-stickiness=200
当我检查集群的状态时，我看到节点之间的奇怪和不同的行为，看起来节点彼此不认识。
NODE1上的 pcs 状态：
[root@rvpcmk01 ~]# pcs status
Cluster name: my_cluster
Stack: corosync
Current DC: rvpcmk01-cr (version 1.1.15-11.el7_3.2-e174ec8) - partition WITHOUT quorum
Last updated: Mon Feb 6 15:18:18 2017 Last change: Mon Feb 6 15:03:03 2017 by root via cibadmin on rvpcmk01-cr
2 nodes and 0 resources configured

PCSD Status:

rvpcmk02-cr: Online

NODE2上的 pcs 状态：
[root@rvpcmk02 ~]# pcs status

我也在两个节点上运行这个命令：
节点1：
[root@rvpcmk01 ~]# pcs status corosync
Membership information
----------------------
Nodeid Votes Name
1 1 rvpcmk01-cr (local)
节点2：
[root@rvpcmk02 ~]# pcs status corosync
Membership information
----------------------
Nodeid Votes Name
2 1 rvpcmk02-cr (local)
据我所知，两个节点都应该出现在上述状态。
你能帮忙并告诉我我在这里缺少什么吗？为什么节点似乎彼此不认识？
这也是我在两台服务器上的 /etc/hosts 文件：
[root@rvpcmk01 ~]# cat /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6

172.17.235.119 rvpcmk01-drbd
172.17.235.46 rvpcmk02-drbd
我检查了授权（当我开始配置集群时肯定是授权的，现在我可以看到有问题，但我不明白它是什么以及它的根本原因是什么：
[root@rvpcmk02 drbd.d]# pcs cluster auth rvpcmk01-cr rvpcmk02-cr -u hacluster -p passwd --debug
