    摘要： Methods, systems, and products for delayed deletion of extended attributes associated with a file in a file system are provided. Embodiments include identifying a file to delete, moving an extended attribute directory associated with the file to a background deletion directory, deleting the file, and deleting in the background the extended attribute directory. Some embodiments also include deleting an ACL associated with the file.

    摘要： An apparatus and method for distributing work on a doubly linked list to a plurality of worker threads are provided. With the apparatus and method, an initial thread obtains the list lock for the linked list and inserts a marker element at the beginning of the linked list. Elements in the linked list that are before the marker element in the linked list are considered work that has been assigned or work that has been completed. Elements of the linked list that are after the marker element in the linked list are work to be done. The initial thread spawns worker threads to perform the work on the linked list and passes the address of the marker element to each of the worker threads. Each worker thread then operates independently to perform work on the linked list based on the current position of the marker element in the linked list.

    摘要： A cluster server manages allocation of free blocks to cluster clients performing writes in a clustered file system. The cluster server manages free block allocation with a free block map and an in-flight block map. The free block map is a data structure or hardware structure with data that indicates blocks or extents of the clustered file system that can be allocated to a client for the client to write data. The in-flight block map is a data structure or hardware structure with data that indicates blocks that have been allocated to clients, but remain in-flight. A block remains in-flight until the clustered file system metadata has been updated to reflect a write performed to that block by a client. After a consistency snapshot of the metadata is published to the storage resources, the data at the block will be visible to other nodes of the cluster.

    摘要： Maintaining a generation value for each fileset that is distinct from a corresponding fileset manager preserves the independence of nodes while also allowing distributed fileset management. A fileset manager can maintain a value that reflects consistency snapshots for that node (“node generation”) separately from a value that reflects consistency snapshots for a particular fileset (“fileset generation”).

    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： Management of a file hierarchy for a clustered file system can be distributed across nodes of the cluster. A cluster file hierarchy is accessed to determine location of a file in response to a request to write to a file. A first node maintains the cluster file hierarchy. It is determined that management of a fileset object, which represents a fileset that includes the file, has been delegated to a second node based, at least in part, on said accessing the cluster file hierarchy. A node file hierarchy maintained by the second node is accessed responsive to determining the delegation. The cluster file hierarchy represents filesets of the clustered file system and the node hierarchy represents a subset of one or more of the filesets. Location of the file is determined based, at least in part, on said accessing the node file hierarchy.
