Node majority with witness (disk or file share)节点多数+见证 Nodes have votes. In addition, a quorum witness has a vote. The cluster quorum is the majority of voting nodes in the active cluster membership plus a witness vote. A quorum witness can be a designated disk witness or a designat...
官方文档给出的建议, 可以在以下情况下,使用文件共享见证: A Cloud Witness can't be used because your cluster nodes don't have a reliable internet connection or an internet connectivity. A disk witness can't be used because there aren't any shared drives to use for a disk witness. For examp...
A Disk Witness isn't supported with Storage Spaces Direct. 如果所有节点都可以访问该磁盘,则通常建议使用磁盘见证。当你需要考虑使用复制存储进行多站点灾难恢复时,建议使用文件共享见证。仅当存储供应商支持从所有站点对复制存储进行读写访问时,才可以配置具有复制存储的磁盘见证。存储空间直通(Storage Spaces Direct...

当Windows故障群集(WSFC)包含偶数个投票节点时,应配置仲裁见证。 如果一半的群集节点同时关闭或断开连接,则添加见证投票会使该群集继续运行。 一般来说,奇数个节点(一般奇数大于或等于3)时无需配置仲裁见证。只有当偶数个节点时需要配置仲裁见证,防止WSFC出现脑裂。一般来说,常见的仲裁见证有下面三种:磁盘见证磁盘见证...
With that said, for a 2-node cluster I would use the same thing regardless of type of cluster. I would add a disk witness to every cluster using shared storage. The cluster services and the disk witness can be hosted on either server and will automatically failover as needed. ...

2016 WSFC开始向最新的技术看齐整合了,存储副本,超融合技术,可以和Azure相配合,实现WSFC on Azure,Azure witness,除了这些还改变了群集默认的检测机制,新导入了瞬断机制,防止由于瞬时中断而导致群集应用故障转移,可以设定在指定时间内群集的故障不需要执行故障转移,如果某时间内发生了某次数的瞬时中断,则判定节点为检疫隔...
