摘要： A method and system for increasing server cluster availability by requiring at a minimum only one node and a quorum replica set of replica members to form and operate a cluster. Replica members maintain cluster operational data. A cluster operates when one node possesses a majority of replica members, which ensures that any new or surviving cluster includes consistent cluster operational data via at least one replica member from the immediately prior cluster. Arbitration provides exclusive ownership by one node of the replica members, including at cluster formation, and when the owning node fails. Arbitration uses a fast mutual exclusion algorithm and a reservation mechanism to challenge for and defend the exclusive reservation of each member. A quorum replica set algorithm brings members online and offline with data consistency, including updating unreconciled replica members, and ensures consistent read and update operations.

摘要翻译： 通过至少要求一个节点和副本成员的仲裁复制集来形成和操作集群，来提高服务器集群可用性的方法和系统。 副本成员维护集群操作数据。 当一个节点拥有大多数副本成员时，集群就会运行，从而确保任何新的或存活的集群通过至少一个来自紧接在前的集群的副本成员包括一致的集群操作数据。 仲裁提供复制成员的一个节点的独占所有权，包括在集群形成时以及所有节点出现故障时。 仲裁使用快速互斥算法和保留机制来挑战和保护每个成员的独家保留。 仲裁复制集算法使成员在线和离线具有数据一致性，包括更新未协调的副本成员，并确保一致的读取和更新操作。
