Abstract: The disclosed embodiments relate to systems and methods for coordinating management of a shared disk storage between nodes. Particularly, a messaging protocol may be used to communicate notifications regarding each node's perception of the shared storage's state. The nodes may use the messaging protocol to achieve consensus when recovering from a storage device failure. Some embodiments provide for recovery when localized failures, such as failures at an adapter on a node, occur.

Abstract: A parity pattern defines a repeated distribution of parity blocks within a distributed parity disk array (“DPDA”). The parity pattern identifies on which disks the parity block or blocks for a stripe are located. When a new disk is added to the DPDA, the parity pattern is modified so that the distribution of parity blocks within the parity pattern is even. Parity blocks within the DPDA are then redistributed to conform with the modified parity pattern.

Abstract: A storage server resizes an array of mass storage devices and distributes data blocks stored in the array of mass storage devices evenly in a declustered organization across the resized array of mass storage devices. Resizing the array of mass storage devices may include adding a new mass storage device to the array or removing a mass storage device from the array. During resizing a data block is moved from one mass storage device to another mass storage device to minimize the imbalance of parity groups shared by the new mass storage devices in the array, as well as minimize the number of data blocks to be moved to uniformly balance the load across the new mass storage device.

Abstract: A data access request is received specifying a data block stored in a stripe of a parity group that includes a plurality of data storage devices to store data blocks and a parity storage device to store parity information for the data. The stripe includes a data block from each of the plurality of data storage devices and the stripe includes a parity block from the parity storage device. An error is detected in the data block specified by the data access request. The error is identified as a lost write error for the data block or a lost write error for the parity block. Identifying the error includes comparing a first storage device signature stored in a metadata field associated with the data block to a second storage device signature stored in a label block identifying a data storage device where the data block is stored.

Abstract: A slice manager module, in the operating system of a storage server, manages the virtual slicing of a mass storage device. The slice manager module receives a notification that a mass storage device has been added to an array of mass storage devices coupled to the storage system. The slice manager module reads header information in the mass storage device to determine a format of the mass storage device. If the mass storage device has not been previously sliced, the slice manager module virtually slices the mass storage device into a plurality of slices, where virtually slicing the mass storage device includes specifying an offset in the mass storage device where each of the plurality of slices is located.

Abstract: The present invention provides a system and method for virtual block numbers (VBNs) to disk block number (DBN) mapping that may be utilized for both single and/or multiple parity based redundancy systems. Following parity redistribution, new VBNs are assigned to disk blocks in the newly added disk and disk blocks previously occupied by parity may be moved to the new disk.

Abstract: Some aspects of the disclosure relate to a data storage system that includes multiple memory device storage devices. If a memory device of a memory device array fails within a first data storage device, some portions of the lost or corrupted data from the failed memory device are recovered by reading them from a second data storage device. Other portions of the lost or corrupted data from the failed memory device are recovered from parity information in the first data storage device.

Abstract: A storage server stores data in a stripe of a parity group that includes a plurality of data storage devices to store data and a parity storage device to store parity information. The stripe includes a data block from each of the data storage devices and a parity block from the parity storage device. The storage server receives a data access request specifying a data block in the stripe, and a lost write detection module detects an error in the data block. The lost write detection module compares a first storage device signature stored in a metadata field associated with the data block to a second storage device signature stored in a global field of the data storage device containing the data block. If the first storage device signature matches the second storage device signature, the lost write detection module compares a consistency point count stored in the metadata field to a reconstructed consistency point count.

Abstract: A parity pattern defines a repeated distribution of parity blocks within a distributed parity disk array (“DPDA”). The parity pattern identifies on which disks the parity block or blocks for a stripe are located. When a new disk is added to the DPDA, the parity pattern is modified so that the distribution of parity blocks within the parity pattern is even. Parity blocks within the DPDA are then redistributed to conform with the modified parity pattern.

Abstract: A triple parity (TP) technique reduces overhead of computing diagonal and anti-diagonal parity for a storage array adapted to enable efficient recovery from the concurrent failure of three storage devices in the array. The diagonal parity is computed along diagonal parity sets that collectively span all data disks and a row parity disk of the array. The parity for all of the diagonal parity sets except one is stored on the diagonal parity disk. Similarly, the anti-diagonal parity is computed along anti-diagonal parity sets that collectively span all data disks and a row parity disk of the array. The parity for all of the anti-diagonal parity sets except one is stored on the anti-diagonal parity disk. The TP technique provides a uniform stripe depth and an optimal amount of parity information.
