摘要： After a clone file is created from a file, a write request targeting the clone file can be handled. It is determined that the write request indicates the clone file that was cloned from a file in a first fileset. The clone file is of a second fileset and a clustered file system comprises the first fileset and the second fileset. A data block of the clone file affected by the write request is determined. It is then determined that the data block at a current location cannot be modified. The write request is implemented with respect to the data block at a different location. It is indicated that the data block at the different location can be modified for subsequent write requests that indicate the clone file

摘要： Embodiments include a computer program product and an apparatus for cloning files across different filesets and maintaining the clone files. After a clone file is created from a file, a write request targeting the clone file can be handled. It is determined that the write request indicates the clone file that was cloned from a file in a first fileset. The clone file is of a second fileset and a clustered file system comprises the first fileset and the second fileset. A data block of the clone file affected by the write request is determined. It is then determined that the data block at a current location cannot be modified. The write request is implemented with respect to the data block at a different location. It is indicated that the data block at the different location can be modified for subsequent write requests that indicate the clone file.

摘要： One embodiment is for using a sparse file as a clone. The method includes creating, by an application associated with a computer system, a snapshot of a file, such as an individual file, a collection of files, file system, directories, and so forth. Further, the method includes requesting, by the application, a clone of that created snapshot. Further still, the method includes generating, by the application, an empty sparse having at least one inode identifying the empty sparse file as the clone and pointing to the snapshot associated with the clone. Thereby, the requested clone is created using the created sparse file, which begins as an empty sparse file.
摘要翻译：一个实施例是使用稀疏文件作为克隆。该方法包括通过与计算机系统相关联的应用来创建诸如单个文件的文件的快照，文件集合，文件系统，目录等。此外，该方法包括由应用程序请求创建的快照的克隆。此外，该方法还包括由应用程序生成具有至少一个标识空稀疏文件作为克隆并指向与克隆相关联的快照的空的稀疏。因此，使用创建的稀疏文件创建所请求的克隆，该稀疏文件以空稀疏文件开头。

摘要： A method, data processing system, and computer program product for managing data. A processor unit copies a data structure within a hierarchy of data structures to form a copy of the data structure. The data structure belongs to a level within a plurality of levels in the hierarchy of data structures. The processor unit associates an identifier with the data structure within the hierarchy of data structures. The processor unit increments a portion of the identifier for the data structure in response to copying the data structure to form the copy of the data structure and associating the identifier with the data structure within the hierarchy of data structures. The portion of the identifier that is incremented is based on the level within the plurality of levels in which the data structure is located.

摘要： Some embodiments of the inventive subject matter allow a redirect-on-write file system to continue processing file transactions while writing a snapshot to persistent storage. Thus, embodiments do not block file transactions while flushing snapshots to persistent storage. To avoid blocking, some embodiments the file system can maintain two snapshot generations. The first snapshot generation is the snapshot being written to persistent storage. The second snapshot generation may reside in main memory, and store data for file transactions occurring after the file system began writing the first snapshot generation.

摘要： A client node on which a file system is mounted can be configured to efficiently handle content access requests after a snapshot is created. The client node can maintain generation numbers at a data block, a file, and a fileset level to determine whether a data block is part of a snapshot generation and consequently whether the data block is writable in a current generation. Data block mappings and write access permissions associated with the data blocks need not be revoked at the client node prior to creating the snapshot. Cached data block mappings can be accessed to identify data blocks for servicing a read request. The data block can be updated in place if the data block is not part of the snapshot generation. The write request can be serviced at a new data block if the data block is part of the snapshot generation.
摘要翻译：安装文件系统的客户端节点可以配置为在创建快照后高效地处理内容访问请求。客户端节点可以在数据块，文件和文件集级别上维护生成号，以确定数据块是否是快照生成的一部分，并且因此数据块是否在当前一代中是可写的。在创建快照之前，不需要在客户机节点撤消与数据块相关联的数据块映射和写访问权限。可以访问缓存数据块映射以识别用于服务读请求的数据块。如果数据块不是快照生成的一部分，则可以更新数据块。如果数据块是快照生成的一部分，则可以在新的数据块处理写入请求。
