起搏器节点不干净（离线）

Question

我正在关注http://clusterlabs.org/doc/en-US/Pacemaker/1.1-pcs/html/Clusters_from_Scratch/_verify_corosync_installation.html文档以在 AWS 中设置 2 节点集群。两个节点都安装了起搏器并启用了 FW 规则。当我在两个节点上运行 pcs status 命令时，我收到消息说另一个节点是 UNCLEAN（离线）。

我设置的两个节点是 ha1p 和 ha2p。

ha1p 上的输出

[root@ha1 log]# pcs status
Cluster name: mycluster
WARNING: no stonith devices and stonith-enabled is not false
Last updated: Wed Dec 24 21:30:44 2014
Last change: Wed Dec 24 21:27:44 2014
Stack: cman
Current DC: ha1p - partition with quorum
Version: 1.1.11-97629de
2 Nodes configured
0 Resources configured


Node ha2p: UNCLEAN (offline)

ha2p 上的输出

[root@ha2 log]# pcs status

/etc/cluster/cluster.conf 的内容如下：

[root@ha1 日志]# cat /etc/cluster/cluster.conf

<cluster config_version="9" name="mycluster">
  <fence_daemon/>
  <clusternodes>
    <clusternode name="ha1p" nodeid="1">
      <fence>
        <method name="pcmk-method">
          <device name="pcmk-redirect" port="ha1p"/>
        </method>
      </fence>
    </clusternode>
    <clusternode name="ha2p" nodeid="2">
      <fence>
        <method name="pcmk-method">
          <device name="pcmk-redirect" port="ha2p"/>
        </method>
      </fence>
    </clusternode>
  </clusternodes>
  <cman expected_votes="1" two_node="1"/>
  <fencedevices>
    <fencedevice agent="fence_pcmk" name="pcmk-redirect"/>
  </fencedevices>
  <rm>
    <failoverdomains/>
    <resources/>
  </rm>
</cluster>

任何帮助将非常感激。

发生这种情况是因为您的集群没有完整的 stonith 配置，处于不干净状态意味着集群不知道节点的状态。
