摘要： When a client requests creation of a production file system or logical unit number (LUN) of storage, a sparse metavolume and a container file system built on the sparse metavolume are implicitly created for containing the production file system or LUN. By implicitly creating one container file system for each production file system or LUN, it is possible to hide the management of the container file system from the client or end user. The creation of snapshot copies in the container file system can also be hidden from the client or end user. Customer service level expectations and thin provisioning can be met automatically by storage policies implemented upon the container file system and the underlying sparse metavolume.

摘要： A file server provides access to a file system built on a logical volume of data storage. The file system includes multiple cylinder groups of file system blocks, and the logical volume includes slices of the cylinder groups. The file server has a storage reorganizer for identifying allocated file system blocks in a selected slice, and evacuating the identified allocated file system blocks from the selected slice. The selected slice is evacuated by reverse mapping each identified allocated block to identify a file to which the identified allocated block is allocated, allocating a new block in another slice, copying data from the identified allocated block to the new block, and substituting the new block for the identified allocated block in the file.

摘要： Storage tiering uses file system awareness of storage class for storage allocation or migration of a storage object from one class of storage to another. For example, the storage object is a production file system, a logical unit number (LUN) of storage, or a snapshot copy of the production file system or LUN. Each storage class may comprise a different back-end disk type, such as Fiber Channel, ATA, etc. Storage allocation or migration is based on storage class to implement a storage policy, such as: (a) move snapshots off the class of storage of the production object and onto a different class of storage; (b) direct new writes to a specified class of storage; or (c) writes targeting a particular storage object are targeted to a particular class of storage.

摘要： A self healing file system is designed for proactive detection and containment of faults, errors, and corruptions, in order to enable in place (online) and non-intrusive recovery. For proactive fault detection, the file system maintains certain per-block metadata of each file system block. The per-block metadata includes a redundancy check, and for file system data blocks, an inode identifier, and an offset of the file system data block in the file including the file system data block. The redundancy check is used to detect and mark bad file system blocks. The inode identifier and offset is used for validating connectivity of the file system blocks to the inodes, and for tracing bad blocks to files that contain the bad blocks.

摘要： A container file system is built on a sparse metavolume for enhanced decoupling of logical storage from physical storage and for providing common supplementary storage services for iSCSI block access and for NFS or CIFS file system access. The container file system contains a production file system or iSCSI LUN and may also contain snapshot copies of the production file system or iSCSI LUN. The container file system manages storage space among the production file system or iSCSI LUN and its snapshot copies, and also improves fault containment. The sparse metavolume provides thin provisioning of the container file system. A slice map indicates whether or not each slice of logical storage in the sparse metavolume is provisioned with an associated configured slice of data storage.

摘要： When a directory tree is migrated from a source file system to a target file system, the directories of the directory tree are retained in the source file system, and handle translation entries are substituted for the regular data files of the directory tree in the source file system. The handle translation entries provide new file handles for the regular data files when the source file system is accessed with old file handles of the regular data files. For example, each handle translation entry includes the old file handle, a file system identifier, and the new file handle. The old file handle provides verification of the file handle being used for accessing the handle translation entry, and the file system identifier identifies the target file system in which the new file handle is valid.

摘要： A data storage server is programmed for management, version control, and scheduling of replication of multiple types of data storage objects including iSCSI LUNs and file systems. The version control determines if two data storage objects are the same or have a common base so that only a difference needs to be transmitted for replication or restoration. A replication job may specify a “one-to-many” replication or a cascaded replication, and any snapshot retention policy is propagated during a cascaded replication. Concurrent replication sessions to the same destination are paced in accordance with respective allocation shares of the reception bandwidth. File handle information is replicated so that a file handle issued by a primary data storage server can be used for accessing a replicated file in a secondary data storage server.

摘要： In response to detection of an error in a filesystem file of a virtually provisioned volume or iSCSI LUN host, where the filesystem file is represented in a container filesystem, a Media Sector Error is returned at the virtual volume layer or the virtual iSCSI layer. The error may be a file allocation correction because of a shared block detected by a filesystem check of the container filesystem. The container may flag the shared block to prompt return of the Media Sector Error in response to attempted access of the block by the host. The host is operative to process the Media Sector Error like a storage subsystem Read Media Error, such that the flagged block is overwritten by the host to clear the error.

摘要： A file is initially created to have metadata and a data block allocation for direct mapping without access to any indirect blocks. Therefore file access performance is increased because the direct mapping eliminates delay otherwise caused by fetching one or more indirect blocks. When needed, the functionality enabled by indirect mapping is provided by creating an indirect mapping for the file and then accessing the file using the indirect mapping. When the functionality enabled by the indirect mapping is no longer needed, the file is reorganized to a direct mapping and then accessed using the direct mapping. For example, a container file for a network attached SCSI LUN is created and accessed without a performance degradation until conversion to an indirect mapping occurs automatically and seamlessly upon activation of a supplementary storage service such as a file-based snapshot copy and replication facility.
摘要翻译：最初创建文件以具有元数据和数据块分配，用于直接映射，无需访问任何间接块。因此，文件访问性能增加，因为直接映射消除了由于获取一个或多个间接块而导致的延迟。当需要时，间接映射启用的功能是通过为文件创建一个间接映射，然后使用间接映射来访问该文件来提供的。当不再需要通过间接映射启用的功能时，将文件重组为直接映射，然后使用直接映射进行访问。例如，创建并访问用于连接SCSI LUN的网络的容器文件，而不会降低性能，直到在激活补充存储服务（例如基于文件的快照副本和复制工具）后，自动和无缝地转换到间接映射。

摘要： Consistency errors may arise during replication of diverse data storage objects from servers in a data network. For preventing consistency errors, a server is programmed for responding to a request for a report of whether or not the server can replicate the dataset without causing a consistency error. Such a report is useful for replicating a consistency group of objects from more than one server. Preparation for replication can be begun at each of the servers, and if any of the servers fail to report that replication can be done without causing a consistency error, the preparation can be aborted so that write access by applications will not be disrupted while the potential problem is diagnosed and eliminated.
摘要翻译：在数据网络中的服务器复制各种数据存储对象时可能会出现一致性错误。为了防止一致性错误，服务器被编程为响应关于服务器是否可以复制数据集的报告的请求而不引起一致性错误。这样的报告对于复制来自多个服务器的对象的一致性组很有用。可以在每个服务器上开始准备复制，如果任何服务器无法报告可以在不导致一致性错误的情况下完成复制，则可以中止准备工作，以便应用程序的写入访问不会中断，同时潜在的问题被诊断和消除。
