四个节点，有两个是新增加的节点，两个老节点间组成集群没有问题，新增加了两个节点，无论是四个组成集群
# --------------------------------- Discovery ---------------------------------- # # Pass an initial list of hosts to perform discovery when new node is started: # The default list of hosts is ["127.0.0.1", "[::1]"] # discovery.zen.ping.unicast.hosts: ["10.96.91.208","10.96.91.209","10.96.91.210","10.96.91.211"] # # Prevent the "split brain" by configuring the majority of nodes (total number of master-eligible nodes / 2 + 1): # discovery.zen.minimum_master_nodes: 3 # # For more information, consult the zen discovery module documentation. #
还是两个节点集群(新旧搭配)

查看日志，可以发现是网络问题。
排查网络
网卡的网络配置
cd /etc/sysconfig/network/ more ifcfg-eth0
网络路由配置
more routes
网关配置
more /etc/resolv.conf
这些配置四台服务器基本都是一样的。所以不是配置问题
继续检查ping 和 traceroute
ping没有问题
traceroute显示不一样，发现有了一个空跳。怀疑是防火墙的问题
查看防火墙的状态
chkconfig --list|grep fire
关闭防火墙
cd /etc/init.d/ ./SuSEfirewall2_setup stop ./SuSEfirewall2_init stop
开机关闭防火墙
chkconfig SuSEfirewall2_setup off
chkconfig SuSEfirewall2_init off
至此，解决问题
