摘要： A method, system, and program are provided for managing a response to an email by a hidden email recipient. A hidden recipient manager detects a request to respond to an electronic communication by a hidden recipient of that electronic communication from among a plurality of recipients of the electronic communication. The hidden recipient detects whether the request to respond is addressed to at least one recipient other than a sender of the electronic communication. If the request to respond is addressed to at least one recipient other than a sender of the electronic communication, then the hidden recipient manager warns the hidden recipient that the request to respond is addressed to at least one recipient who is unaware of the recipient of the electronic communication by the hidden recipient.

摘要： An operating system manages virtualized instances of hardware resources and migration enabled applications partitioned into one of multiple partitions with a separate operating system kernel running in each of the partitions. A migration event controller of the operating system manages the checkpoint and restart process during migration of a virtualized instance of at least one migration enabled application from a departure partition to an arrival partition. The migration event controller supports migration enabled applications to separately specify at least one application specific checkpoint script and restart script to be triggered by checkpoint and restart events by the migration event controller so the at least one migration enabled application can participate in performing the checkpoint and restart process for additional state information during migration of the virtualized instance from the departure partition to the arrival partition.

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： 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： In a cluster that distributes fileset management, fileset managers will maintain a free block map and an in-flight block map to allocate blocks to clients writing to a relevant fileset. A fileset manager managing free block allocation for cluster clients that write to a fileset managed by the fileset manager. Since a clustered file system manager manages an initial free block map for the cluster (“cluster free block map”), the clustered file system manager provisions free blocks to fileset managers from the cluster free block map. The fileset manager then allocates free blocks from the provisioned free blocks to cluster clients that write to the fileset managed by the fileset manager.

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： Embodiments include a method for removing a file within a redirect-on-write file system. In some embodiments, a file removal operation is detected in a file management unit, which resides in a memory unit. It is then determined that the number of free data blocks in the persistent storage is below a minimum threshold. The file removal operation is written to a log used for storing system operations. A file management unit is notified of the successful write of the file removal operation to the log used for storing system operations. The data blocks are moved from the file selected for removal to a list of free data blocks. The indirect blocks from the file selected for removal are moved to a data block removal list.

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： Embodiments include a method comprising detecting addition of a new nonvolatile machine-readable medium to a data storage pool of nonvolatile machine-readable media. The method includes preventing from being performed a first operation of a file system that requires a first parameter that identifies a logical indication of a location within the nonvolatile machine-readable media for the file system, until logical indications of locations within the new nonvolatile machine-readable medium for the file system have been stored in the data storage pool. The method includes allowing to be performed, prior to logical indications of locations within the new nonvolatile machine-readable medium being stored in the data storage pool, a second operation of the file system that does not require a second parameter that identifies a logical indication of a location within the nonvolatile machine-readable media, wherein the second operation causes data to be written into the new nonvolatile machine-readable medium.
