Abstract: Example embodiments relate to automatic WORM-retention state transitions. In example embodiments, a storage computing device may detect a request to access, via a file system, a file that is associated with a first retention state. The first retention state may indicate either a first type of WORM-retention protection for the file or no WORM-retention protection for the file. The storage computing device may determine, in response to the request, that the file should be designated with a second retention state. The second retention state may indicate a second type of WORM-retention protection for the file. The determination may be based on a retention policy file that is tightly integrated with the file system and metadata of the file. The storage computing device may transition the file (e.g., by communicating with the file system) to be associated with the second retention state instead of the first retention state.

Abstract: Systems, methods and computer program products are disclosed for associating unique identifiers to files of a file system to indicate that the contents of the files have changed. In some implementations, a counter value associated with a file is incremented or decremented each time the file contents are changed. The unique identifier may be stored with the file contents and file metadata in the cache. When a process requests access to the cached file contents, the process requests the unique identifier from a system component and compares the unique identifier with the unique identifier returned by the system component. If the two unique identifiers are the same, the cached file contents are deemed valid and can be used by the process. If the two unique identifiers are different, the cached file contents are deemed invalid.

Abstract: A file system that operates on an underlying volume that has multiple tiers, each tier including a particular trait set. Upon creating or otherwise identifying a file system namespace (such as a directory or file) that is in a volume or that is to be included within the volume, a storage trait set to be applied corresponding to the file system namespace is identified. Then, the storage trait set is compared against the trait sets for the multiple tiers to identify a tier into which to store the file system namespace. The file system namespace is then caused to be stored within the identified tier. Thus, the file system is provided with a volume that has multiple tiers (each having different trait sets) to choose from in storing files.

Abstract: A cluster of computer system nodes connected by a storage area network include two classes of nodes. The first class of nodes can act as clients or servers, while the other nodes can only be clients. The client-only nodes require much less functionality and can be more easily supported by different operating systems. To minimize the amount of data transmitted during normal operation, the server responsible for maintaining a cluster configuration database repeatedly multicasts the IP address, its incarnation number and the most recent database generation number. Each node stores this information and when a change is detected, each node can request an update of the data needed by that node. A client-only node uses the IP address of the server to connect to the server, to download the information from the cluster database required by the client-only node and to upload local disk connectivity information.

Abstract: When a file system manager responds to a request to write data to a specified number of blocks of a file, the file system manager determines that corresponding file system data block allocations exist and determines that the file is fragmented over the corresponding file system data block allocations. In response to determining that the file is fragmented over the corresponding file system data block allocations, the file system manager allocates and substitutes a single extent of contiguous file system data blocks for the corresponding file system data block allocations, and writes data to the newly allocated contiguous file system data blocks. For example, the file system manager compares a spread and a count of extent fragments of the file system data block allocations to appropriate thresholds to trigger the defragmentation upon file over-write.

Abstract: The management of data storage channel utilization in a computing system that has multiple users. The system receives file-level requests from requesters and then creates a history for each requester. Upon evaluating the history of each requester, the system determines whether to delay the file-level requests from entering the file system stack based on the result of the evaluation. The system delays one or more of the file-level requests if the history of the corresponding requester meets one or more criteria. If the history of the corresponding requester does not meet the criteria, the system allows the file-level requests to be passed to the file system stack without being delayed.
