摘要： A system and method for managing file data during consistency points in a file system is provided. A buffer data control structure is modified to include a flags array that tracks various status flags for both a current and a next consistency point (CP). By utilizing multiple pointers within a buffer control structure, the file system may permit write operations to continue to a file undergoing write allocation. Received writes during a write allocation procedure are stored in raw data buffers and the buffer control structure is marked as being dirty for a next CP.

摘要： A system and method for managing data during consistency points in a storage system is provided. A buffer data control structure is modified to include a flags array that tracks various status flags for both a current and a next consistency point (CP). By utilizing multiple pointers within a buffer control structure, the storage system may permit write operations to continue to a data container undergoing write allocation. Received writes during a write allocation procedure are stored in raw data buffers and the buffer control structure is marked as being dirty for a next CP.

摘要： A network storage filer implements a four-phase commit protocol to coordinate consistency points among a group of volumes (a “group consistency point”) such that, upon recovery, all volumes of the group reflect consistency points taken at the same time. The filer records progress at each phase while creating the consistency points of the volumes. Upon recovery, the same or a different filer uses the last recorded progress indicator to ascertain whether the consistency points were completed on all of the volumes in the group. If all the volume consistency points of the group consistency point were completed, the filer users the volume consistency points to mount the volumes. Otherwise, the filer uses an earlier group consistency point to mount the volumes. In either ease, the volumes are consistent with each other.
摘要翻译：网络存储文件管理器实现四阶段提交协议来协调一组卷（“组一致性点”）中的一致性点，以便在恢复时，组中的所有卷都反映了同时采用的一致性点。文件管理器记录每个阶段的进度，同时创建卷的一致性点。恢复后，相同或不同的文件管理器使用最后记录的进度指标来确定组中所有卷的一致性点是否完成。如果组一致性点的所有卷一致性点都已完成，则文件管理器将使用卷一致性点来装载卷。否则，文件管理器使用较早的组一致性点来装载卷。容易，体积相互一致。

摘要： A method for transferring data of a hybrid virtual volume of a computer data storage system from a source to a destination is disclosed. The method first translates intermingled virtual and physical volume block numbers of the hybrid virtual volume into a data stream having only virtual volume block numbers. The method then sends the data stream to a destination computer.

摘要： A system and method for detecting buffer leaks in a files system utilizing consistency points is provided. Upon receipt of a write operation, a buffer check control structure is written to a raw data buffer. The buffer check control structure comprises a set of magic numbers and a consistency point counter identifying the current CP. At write allocation time, the buffer check control structure is examined to determine that the buffer is being committed to disk during the correct CP.

摘要： A technique translates a hybrid virtual volume (vvol) having a file system that contains intermingled virtual and physical volume block numbers (vbns) into a “pure” stream of virtual vbns (vvbns). The stream of vvbns is illustratively embodied as an output file system data stream of a vvol image that is transferred by a source storage system (“source”) to a destination storage system (“destination”) in accordance with image transfer operations, such as volume copying and synchronous or asynchronous mirroring, provided by a volume replication facility. The blocks that are sent as part of the image transfer are selected from a container file of the hybrid vvol on the source. In particular, the invention is directed to a technique for translating physical vbns (pvbns) of a source aggregate on the source to pure vvbns of the output file system data stream that can be used on a destination aggregate of the destination, where embedded pvbns in the source hybrid vvol image are not valid.

摘要： A technique converts a stream of virtual volume block numbers (vvbns) into a hybrid virtual volume (vvol) file system containing both physical volume block numbers (pvbns) and vvbns. The stream of vvbns is illustratively embodied as a file system data stream of a vvol that is transferred by a source to a destination in accordance with image transfer operations, such as volume copying and synchronous or asynchronous mirroring. Transfer of the vvol involves converting a file system on the source vvol into the file system data stream (i.e., a “pure” vvol stream), where all blocks of the vvol are represented by vvbns. The file system data stream is then transferred to the destination, where the vvbns of the pure vvol stream blocks are converted to pvbns of a hybrid stream.
