    摘要: A system provides referencing from one file system server to another through the use of a file system location database improving movement and replication of file systems. When a file system is moved from a first file system server a data object that references the file system remains in the first server and contains information used to find the current location of the file system. The actual location of the file system is stored in the separate file system location database which contains the locations of file systems on a number of file system servers. This allows the data in a file system to be replicated or moved without requiring updates to the data in any redirecting or referencing servers.

    摘要: A method and system for replicating a file system organized as a data structure from a source server to a target server. The replication process preserves the order of the inode table entries in the target file system at all stages of the replication process, as well as the internal consistency of the replica of the data structure on the target server.

    摘要: An apparatus, graphical user interface, system, and method are provided for presenting a mapping between a namespace and a set of computing resources. The apparatus includes an input module, a format module, and an output module. The input module obtains a mapping between namespace identifiers and a set of computing resources. The format module associates a namespace identifier and a computing resource according to the mapping. The output module provides the namespace identifiers and the associated computing resource corresponding to each namespace identifier. A graphical user interface includes a window with a file system pane and a fileset pane. The file system pane includes a first tree control that displays the components of the file system. The fileset pane includes a second tree control that displays the filesets. The tree controls are updated in response to user input in either the file system pane or the fileset pane.

    摘要: A method and system for managing availability of a dependent thread to service a nested request is provided. A plurality of reply threads are maintained in a single thread pool. In addition, a counter is provided to track availability of a reply thread from the thread pool. A service thread that requires at least one reply thread to complete execution of a request must check the counter to determine availability of the reply thread prior to execution of the request. The process of determining availability of a reply thread prior to execution of a service thread request avoids initiating execution of a request that cannot be completed in a timely manner, or at all.

    摘要: Multiple data access techniques are communicated to a client machine requesting access to a shared resource. In response to the returned techniques, the client machine may select one technique for accessing the shared resource. Although the client machine may implement one or more of the techniques to read or write data to the shared resource, different techniques may be preferable based upon protection and privacy associated with the access. A method for the client machine selecting a preferred data access technique may be based upon a topological relationship of the client machine to data storage or a server selected technique.

    摘要: A source site employs a source server and a source storage system, and a target site employs a target server and a target storage system. The source server manipulates data that is stored within a source logical unit of the source storage system. The target server generates a flashcopy of a replica volume and performs a recovery of the flashcopy of the replica volume in response to the replica volume being a replication of a storage volume received by the target storage system from the source storage system. The target server further exports data of the recovered flashcopy of the replica volume whereby the recovered flashcopy of the replica volume is made available to a client.

    摘要: Improved techniques are disclosed for accessing content in file systems, allowing file system clients to realize advantages of file system referrals even though a file access protocol used by the client is not specifically adapted for referral objects. (For example, the client may have a legacy file system protocol or a proprietary file system protocol which does not support referrals.) These advantages include a uniform name space view of content in a network file system, and an ability to locate content in a (nearly) seamless and transparent manner, even though the content may be dynamically moved from one location to another or replicated in different locations. A file system server returns a symbolic link in place of a referral, and an automated file mounting process on the client is leveraged to access the content using the link. Built-in crash recovery techniques of the file system client are leveraged to access moved content.

    摘要: Extensions are provided to a lock for supporting concurrency of read and write operations of a shared resource in a computer system. Both reader and writer modes are maintained. In addition, an append mode and a prefix mode are provided. The append mode supports non-exclusive access to the shared resource while enabling modification of the shared resource after a marker. The prefix mode supports non-exclusive access to read the shared resource prior to the marker. Lock mode requests to the shared resources are mediated to ensure compatibility of granted lock modes with lock mode requests.

    摘要翻译: 扩展被提供给用于支持计算机系统中的共享资源的读写操作的并发的锁。 读写器模式都保持不变。 此外,还提供了附加模式和前缀模式。 附加模式支持对共享资源的非独占访问,同时在标记之后修改共享资源。 前缀模式支持非独占访问,以在标记之前读取共享资源。 对共享资源的锁定模式请求是中介的,以确保授权的锁定模式与锁定模式请求的兼容性。
