摘要： A cluster system including as few as two cluster nodes and a plurality of links, each one of the plurality of links coupling one of the cluster nodes to a voting device wherein a single surviving cluster node obtain a vote from the voting device. A method of establishing quorum in a cluster system including as few as two cluster nodes, the method comprising determining a single surviving cluster node of the as few as two cluster nodes, obtaining a vote from a voting device, and establishing quorum such that cluster operations are continued by the single surviving cluster node. A method for preventing a partition-in-time quorum establishment problem in a cluster system including as few as two cluster nodes, the method comprising determining that a revived cluster node is also a sole active cluster node of the cluster system, checking a last-surviving flag of the sole active cluster node, and if the last-surviving flag is set to FALSE, not restarting cluster operations.
摘要翻译： 包括少至两个群集节点和多个链路的群集系统，所述多个链路中的每一个将所述群集节点中的一个链接到投票设备，其中单个幸存群集节点从所述投票设备获得投票。 一种在包括少至两个集群节点的集群系统中建立仲裁的方法，所述方法包括：确定少至两个集群节点中的单个幸存集群节点，从投票设备获取投票权，并建立群集操作 由单个幸存的群集节点继续。 一种用于在包括少至两个集群节点的集群系统中防止时间段仲裁建立问题的方法，所述方法包括确定恢复的集群节点也是集群系统的唯一主动集群节点， 唯一活动群集节点的生存标志，如果最后一个生存标志设置为FALSE，则不重新启动集群操作。
