Abstract: A cluster based file service may operate on a cluster of two or more independent devices that have access to a common data storage. The file service may have a namespace definition with each device in the cluster, but may be modified by any device operating the file service. Each instance of the file service may identify and capture a command that changes the namespace structure and cause the change to be propagated to the other members of cluster. If one of the devices in the cluster does not successfully perform an update to the namespace structure, that device may be brought offline. The cluster based file service may permit adding or removing devices from the cluster while the file service is operating, and may provide a high throughput and high availability file service.

Abstract translation: 基于集群的文件服务可以在具有访问公共数据存储的两个或更多个独立设备的集群上操作。 文件服务可能具有集群中每个设备的命名空间定义，但可由任何操作文件服务的设备进行修改。 文件服务的每个实例可以识别和捕获改变命名空间结构并使更改传播到群集的其他成员的命令。 如果集群中的某个设备未成功执行命名空间结构的更新，则该设备可能会脱机。 基于集群的文件服务可以允许在文件服务运行时从集群添加或删除设备，并且可以提供高吞吐量和高可用性文件服务。

Abstract: The present invention extends to methods, systems, and computer program products for implementing persistent reservation techniques for establishing ownership of one or more physical disks. These persistent reservation techniques can be employed to determine ownership of physical disks in a storage pool as well as in any other storage configuration. Using the persistent reservation techniques of the present invention, when a network partition occurs, a defender of a physical disk does not remove a challenger's registration key until the defender receives notification that the challenger is no longer in the defender's partition. In this way, pending I/O from applications executing on the challenger will not fail due to the challenger's key being removed until the proper ownership of the physical disk can be resolved.
