Systems and methods of performing lightweight fault monitoring and analysis are described. In certain embodiments, the lightweight fault monitoring and analysis system and method include a crash dump component operable to generate a lightweight core file for a machine without generating a complete core file. The lightweight core file is smaller in size than a complete core file and contains information relevant for fault monitoring and analysis. The lightweight core has a data structure portion reflecting the state of only a portion of actual working memory at the time of a problem. The lightweight core file contains both regions in memory specific to the problem encountered and some standard regions.

A method and apparatus for retention of active data stored in memory using multiple indexing systems for data storage. An embodiment of a method for retention of active data in a storage server includes reading data into a first location of a main memory of the storage server. The data in the first location indexes data elements in a long-term data storage in a first manner. The method further provides for copying the data from the first location into a second location in the main memory of the storage server, where the data in the second location indexing the data elements in the long-term data storage in a second manner.

Methods of operating a computer storage system where an identical copy of a mirror source filesystem is maintained on a mirror destination storage volume managed by a mirror destination server. A modification to the mirror source filesystem is planned and executed, and a corresponding change to the mirror destination filesystem is accomplished by storing data directly to the mirror destination storage volume, bypassing filesystem logic that interprets the data stored on the volume. Systems that implement these methods are also described.

A network caching system has a multi-protocol caching filer coupled to an origin server to provide storage virtualization of data served by the filer in response to data access requests issued by multi-protocol clients over a computer network. The multi-protocol caching filer includes a file system configured to manage a sparse volume that “virtualizes” a storage space of the data to thereby provide a cache function that enables access to data by the multi-protocol clients. To that end, the caching filer further includes a multi-protocol engine configured to translate the multi-protocol client data access requests into generic file system primitive operations executable by both the caching filer and the origin server.

A volume metadata manager manages volume metadata including antivirus attributes. When a volume is to be relocated, the volume metadata manager updates a generation indicator in volume-level metadata for the volume but does not update a generation indicator in file-level metadata for a file in the volume. After the volume is relocated, the volume metadata manager updates the generation indicator and antivirus attributes of the file when the file is requested for access.

A technique for efficiently scanning various datasets in a storage system to generate metadata for shared data blocks is provided. In one embodiment, data containers in an active file system of a storage object are first scanned. Remaining images (e. g. , snapshots of the file system) are arranged in a chronological order based on the age of such images in the storage object. In some instances, to perform a metadata scan of a given image, the storage server compares each data container in the given image to a corresponding data container in a prior image (from the chronological order) to identify any non-identical data blocks (i. e. , blocks that are not common between the data containers of the two images) in each data container. The metadata scanner then generates metadata only for the non-identical data blocks in each data container and skips metadata generation for any remaining data blocks.
