底层为提供心跳功能的corosync,pacemaker在底层还需要依赖Resource Agent和Cluster Glue这两个组件来实现将本身不具备高可用能力的资源构建成高可用服务;其中Resource Agent是依赖于Cluster Glue的;pacemaker在上层还支持集群共享文件系统:cLVM2、GFS2、OCFS2(只能在集群中使用);集群共享文件系统需要分布式锁管理器来解决多节点...

1、DRS:分布式资源调度,用于动态调整Cluster中ESX主机负载,自动把负载较重的主机上的虚拟机通过VMotion迁移到负载较轻的主机上,最终达到整个Cluster中的主机资源消耗平衡。 2、HA:高可用性,用于意外故障切换,当监控到Cluster中有主机意外故障时,会自动在其他主机上启动故障主机上之前承载的虚拟机。
HA cluster authcode The value is automatically generated by the system and is used for mutual verification between the primary and secondary nodes. When configuring HA parameters for the primary node, record the verification key of the HA group and configure the parameters for the secondary node ...
Cluster中的Master角色主机通过网络心跳检测Slaver主机和VM虚拟机的健康状态,当我们创建vKernel端口组的时候,里面有一个Management Traffic选项就是将该端口组声明为网络心跳。 3.存储心跳 有时可能我们的Esxi主机是正常的但是由于网络的故障,无法与Master进行通讯,为了避免误判,所以从vSphere5.0以后引入了存储心跳,当网络心...
