摘要： A method for performing file lookups based on tags indicative of file characteristics may involve: a file system storing an association between a tag and a file, where the tag is indicative of a characteristic of the file; the file system storing an additional association between the tag and an additional file that also has the characteristic; the file system searching for files having the tag; and in response to searching, the file system returning identifiers of both files associated with the tag. The returned identifiers may include the files' pathnames or inode identifiers of the files' inodes.

摘要： A bridge in a file server provides a direct link to data storage devices in satisfaction of data requests. The file server has one or more function-specific processors, including network processors (NPs) and file storage processors (FSPs), all operating in parallel and communicating over an interconnect bus. Each FSP is also connected to one or more disk controllers which in turn manage one or more data storage devices. To minimize local bus contention between data storage devices and network communications, separate internal buses are provided in the FSP, one internal bus connected to the interconnect bus for network communications and one internal bus connected to disk controllers for performing I/O operations on data storage devices. The bridge provides a path between the FSP's internal buses so that, for disk access requests, data from a particular data storage device may be sent by the disk controller via the bridge over the interconnect bus to the NP servicing the request with minimal involvement of the local FSP processor.
摘要翻译：文件服务器中的一个桥接器可以直接链接到满足数据请求的数据存储设备。文件服务器具有一个或多个功能特定的处理器，包括网络处理器（NP）和文件存储处理器（FSP），所有这些处理器都通过并行运行并通过互连总线进行通信。每个FSP还连接到一个或多个磁盘控制器，磁盘控制器又管理一个或多个数据存储设备。为了最小化数据存储设备和网络通信之间的局部总线争用，FSP中提供单独的内部总线，一条内部总线连接到互连总线进行网络通信，一条内部总线连接到磁盘控制器，用于对数据存储执行I / O操作设备。该桥提供了FSP内部总线之间的路径，因此，对于磁盘访问请求，来自特定数据存储设备的数据可以由磁盘控制器通过互连总线上的桥发送到NP，以最少的参与本地FSP处理器。

摘要： A node in a server cluster is designated as a quorum disk. The node stores a list of other nodes in the server cluster also designated as quorum disks. The node can replace the first list with a second and more recent list of quorum disks only if the second list is updated on at least a simple majority of quorum disks on the first list.

摘要： Embodiments of a system and method for distributed file system I/O recovery in storage networks. Embodiments may detect loss of access to a server in the storage network and recover application I/O requests in real-time once access to the server is restored. Embodiments may detect server and/or network failures and store failed and new I/O requests. Recovery from the failure (e.g. network reconnect, server node reboot, or failover, if this is a clustered environment) may be detected and, after recovery is detected, any stored failed and new I/O requests may be sent to the server. In one embodiment, to detect recovery from the failure, a failed I/O request may be repeatedly re-issued until the I/O request succeeds. Embodiments may be implemented in a variety of storage environments, including environments where clients issue direct I/O over a storage network to storage and control I/O over a network to a server.
摘要翻译：存储网络中分布式文件系统I / O恢复的系统和方法的实施例。实施例可以检测对存储网络中的服务器的访问的丢失，并且恢复对服务器的访问时实时地恢复应用I / O请求。实施例可以检测服务器和/或网络故障并存储失败的和新的I / O请求。可以检测到从故障恢复（例如，网络重新连接，服务器节点重新启动或故障转移（如果是集群环境）），并且在检测到恢复之后，可以将任何存储的故障和新的I / O请求发送到服务器。在一个实施例中，为了从故障中检测恢复，可能会重复发出失败的I / O请求，直到I / O请求成功。实施例可以在各种存储环境中实现，包括客户端通过存储网络发出直接I / O以将网络上的I / O存储和控制到服务器的环境。
