    摘要： A technique is disclosed for restoring data of sparse volumes, where one or more block pointers within the file system structure are marked as ABSENT, and fetching the appropriate data from an alternate location on demand. Client data access requests to the local storage system initiate a restoration of the data from a backing store as required. A demand generator can also be used to restore the data as a background process by walking through the sparse volume and restoring the data of absent blocks. A pump module is also disclosed to regulate the access of the demand generator. Once all the data has been restored, the volume contains all data locally, and is no longer a sparse volume.

    摘要翻译： 公开了一种用于恢复稀疏卷的数据的技术，其中文件系统结构中的一个或多个块指针被标记为ABSENT，并且根据需要从备用位置获取适当的数据。 对本地存储系统的客户端数据访问请求根据需要启动从后台存储器恢复数据。 还可以使用需求生成器通过遍历稀疏卷并恢复缺席块的数据来将数据恢复为后台进程。 还公开了一种泵模块来调节需求发生器的通路。 一旦所有数据都已恢复，卷将包含本地的所有数据，并且不再是稀疏卷。

    摘要： A network cache is automatically configured so that the network cache is able to communicate with a database to authenticate a user. A user ID is received as input and is used to query a database for objects having the user ID. The user object corresponding to the user ID is selected and the attributes within the user object are output to a user interface. The attribute name corresponding to the user ID is selected. Attribute names corresponding to group IDs in the user object are selected. If other forms of group membership exist, a non-parent object is retrieved and the attribute name corresponding to the group ID in the object is selected. Once each attribute name is selected the attribute name is stored in a configuration file in the network cache.

    摘要： A system and method for storing and retrieving file system log information in a cluster computer system is provided. In response to an aborted takeover operation, a surviving storage system stores a set of file replay log information on storage devices associated with the surviving storage system. When the failed storage system re-initializes, it retrieves the file replay log information from the surviving storage system and utilizes the file replay log information to render its disks consistent.
