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： In one form, in a method for mapping file handles, protocol data elements are created for respective file system protocols. Such a protocol data element identifies a structure of server handles for the data element's corresponding protocol. File system data elements are created for server file systems. Such a file system data element includes a file system identification (FSID) attribute. Responsive to accessing an object of one of the server file systems, a value for the FSID attribute of the corresponding file system data element is created for reconstructing the object's server handle. Creating the value includes parsing, responsive to one of the protocol data elements, an FSID of a server handle for the object.

摘要： A method and system for allocating blocks of disk in persistent storage to requesting threads. A primary data structure is provided for organizing and categorizing blocks of disk space. In addition, a secondary data structure is provided for maintaining a list of all active file system processes and blocks of disk space used by those processes. Blocks of disk space are assigned to pages. At such time as a thread may request allocation of disk space, both data structures are reviewed to determine if the requested disk space is available and to limit access of available disk space to a single page of memory to a single thread at any one time.

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.
摘要翻译：系统通过使用文件系统位置数据库提供从一个文件系统服务器引用另一个文件系统服务器，从而改善文件系统的移动和复制。当文件系统从第一个文件系统服务器移动时，引用该文件系统的数据对象将保留在第一个服务器中，并包含用于查找文件系统当前位置的信息。文件系统的实际位置存储在单独的文件系统位置数据库中，其中包含多个文件系统服务器上的文件系统的位置。这允许复制或移动文件系统中的数据，而无需更新任何重定向或引用服务器中的数据。

摘要： In a cluster of computing nodes having shared access to one or more volumes of data storage using a parallel file system, a method for managing the data storage includes initiating a data management application in the cluster using a data management application programming interface (DMAPI) of the parallel file system. When a request submitted to the parallel file system is received on one of the nodes to perform an operation on a file in one of the volumes of data storage, a data management access right is obtained from the DMAPI responsive to the request The operation is performed on the file using the access right.

摘要： In one form, in a method for making file systems accessible, a referring file system attribute is created, responsive to a first file system having a referral object referring to a second file system. The referring file system attribute describes referring file system identification for the first file system. A path attribute is created, responsive to the first file system having the referral object, describing a path from a root of the first file system to the referral object. A referred file system attribute is created, responsive to the first file system having the referral object, describing a referred file system identification for the second file system. A parent attribute is created, responsive to the first file system having the referral object, describing a parent flag for the second file system.
