    • A computer network file system is described. The computer network file system includes first metadata, which is managed primarily by a first file server that is operably connected to a network fabric. The first metadata includes first file location information, and the first file location information includes at least one server id. The computer network file system also includes second metadata, which is managed primarily by a second file server that is operably connected to a network fabric. The second metadata includes second file location information, and the second file location information includes at least one server id. The first metadata and the second metadata are configured to allow a requestor to locate files that are stored by the first file server and files that are stored by the second file server in a directory structure that spans the first file server and the second file server.
    • 描述了计算机网络文件系统。 计算机网络文件系统包括主要由可操作地连接到网络结构的第一文件服务器管理的第一元数据。 第一元数据包括第一文件位置信息,并且第一文件位置信息包括至少一个服务器ID。 计算机网络文件系统还包括主要由可操作地连接到网络结构的第二文件服务器管理的第二元数据。 第二元数据包括第二文件位置信息,第二文件位置信息包括至少一个服务器ID。 第一元数据和第二元数据被配置为允许请求者将由第一文件服务器存储的文件和由第二文件服务器存储的文件定位在跨越第一文件服务器和第二文件服务器的目录结构中。

    • A system and method for replacing file system processors, also known as hot swapping, is described. The system and method operate on a fault-tolerant network file system that includes a first file server that is operably connected to a network fabric and a second file server that is operably connected to the network fabric. The fault-tolerant network file system includes a first disk array that is operably coupled to the first file server and to the second file server and a second disk array that is operably coupled to the first file server and to the second file server. First file system information is loaded on the first file server. The first file system information includes a first intent log of proposed changes to first metadata. Second file system information is loaded on the second file server. The second file system information includes a second intent log of proposed changes to second metadata. The first file server has a copy of the second metadata, and the second file server maintains a copy of the first metadata, thereby allowing the first file server to access files on the second disk array in the event of a failure of the second file server.
    • 描述了用于替换文件系统处理器(也称为热插拔)的系统和方法。 系统和方法在容错网络文件系统上操作,所述容错网络文件系统包括可操作地连接到网络结构的第一文件服务器和可操作地连接到网络结构的第二文件服务器。 容错网络文件系统包括可操作地耦合到第一文件服务器和第二文件服务器的第一磁盘阵列和可操作地耦合到第一文件服务器和第二文件服务器的第二磁盘阵列。 第一个文件系统信息被加载到第一个文件服务器上。 第一文件系统信息包括对第一元数据的建议改变的第一意图日志。 第二个文件系统信息被加载到第二个文件服务器上。 第二文件系统信息包括对第二元数据的建议改变的第二意图日志。 第一文件服务器具有第二元数据的副本,并且第二文件服务器维护第一元数据的副本,从而允许第一文件服务器在第二文件服务器发生故障的情况下访问第二磁盘阵列上的文件 。
