    • A system for replicating a filesystem running on multiple nodes comprising an originator system and a replica system. The originator system includes a plurality of nodes. The replica system includes a plurality of nodes and a processor. The plurality of nodes of the replica system are paired with the plurality of nodes of the originator system. The processor is configured to receive an indicator of a node of the plurality of nodes of the replica system finishing replication for a view of a filesystem at a point in time. The processor is further configured to indicate that replication for the view of the filesystem is complete in the event that all replica system nodes have received their indication for the view.
    • 用于复制在包含发起者系统和副本系统的多个节点上运行的文件系统的系统。 发起者系统包括多个节点。 复制系统包括多个节点和处理器。 复制系统的多个节点与发起者系统的多个节点配对。 所述处理器被配置为接收所述副本系统的所述多个节点中的节点的指示符,以完成针对文件系统的视图在某个时间点的复制。 处理器还被配置为指示在所有副本系统节点已经接收到其对于视图的指示的情况下,用于文件系统的视图的复制是完整的。

    • Data replication comprises: redistributing one or more originator data subsets among a plurality of originator nodes; determining data redistribution information pertaining to redistribution of the one or more originator data subsets among the plurality of originator nodes; and sending data redistribution information to a replica system. The data redistribution information is used by the replica system to redistribute one or more corresponding replica data subsets among a plurality of replica nodes; and the one or more corresponding replica data subsets are redistributed among the plurality of replica nodes without requiring the one or more originator data subsets to be sent to the replica system during redistribution.
    • 数据复制包括:在多个发起者节点之间重新分配一个或多个发起者数据子集; 确定与所述多个发起者节点中的所述一个或多个发起者数据子集的再分配有关的数据再分配信息; 并将数据再发布信息发送到副本系统。 复制系统使用数据再分配信息来重新分配多个复制节点之中的一个或多个对应的副本数据子集; 并且在多个副本节点之间重新分配一个或多个对应的副本数据子集,而不需要在再分配期间将一个或多个发起者数据子集发送到副本系统。
