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.
摘要翻译：本发明主题的一些实施例允许写入时重写文件系统在将快照写入持久存储器的同时继续处理文件事务。因此，实施例在将快照刷新到持久存储器时不阻止文件事务。为了避免阻塞，文件系统的一些实施例可以维护两个快照世代。第一个快照生成是将快照写入持久存储。第二个快照生成可以驻留在主存储器中，并存储在文件系统开始写入第一个快照生成之后发生的文件事务的数据。

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.

摘要： Hierarchical recovery of failed computing nodes to operative computing nodes within a cluster of computing nodes is managed by initiating a recovery leader at an operative node that retrieves management information from the operative nodes and applies the management information to recover filesets of a meta-fileset in a hierarchical filesystem. The use of hierarchical filesets throughout the cluster provides more rapid failover by distributing recovery load across computing nodes and supporting recovery of nodes in parallel.

摘要： Various embodiments are directed to maintaining versions of data within a solid state memory. At least one request to write at least one dataset to a logical page of a solid state memory is received from a file system. At least one physical page in a data block of the solid state memory associated with the logical page is identified. A processor stores the dataset in the at least one physical page. At least one data versioning tag is associated with the at least one dataset in a data structure associated with the logical page. The data versioning tag identifies the at least one dataset as a given version of the logical page. The at least one dataset is maintained as accessible from the at least one physical page irrespective of subsequent write operations to the logical page in response to associating the at least one data versioning tag.

摘要： One or more embodiments are directed to managing data in a solid state memory supporting data versioning. A file system residing at an information processing system reserves a plurality of logical pages from a solid state memory. Each logical page in the plurality of logical pages is associated with a plurality of physical pages in the solid state memory. Each logical page in the plurality of logical pages is assigned to one group in a plurality of groups. A request is sent to a flash translation layer for an operation to be performed by the flash translation layer on a group in the plurality of groups.
