摘要： A system and method for data storage in an array. A system includes a client coupled to a storage subsystem including data storage locations addressable as rows and columns in an array. Each column comprises a separate storage device. Each row includes redundant data. For a given row, a coordinating storage device coordinates the computation and storage of redundant data. The system detects a failure of a storage region and in response, configures an overlay storage device to temporarily overlay the failed region, maintains an association between the overlay device and the failed region, and maintains a record of changes made to the overlay device while the region is in a failed state. In response to detecting that the failed region has been restored, the system uses the association to identify the overlay device and uses the record of changes made to the overlay device to resynchronize the failed region.

摘要： Systems and methods for repairing a failed component within a data storage subsystem without interruption of service. A client device is coupled to a data storage cluster comprising a plurality of data storage locations addressable as rows and columns in an array. Each column of the array comprising a separate computer interconnected to other columns via a network. After both detecting a failure of a first column in the array and detecting a predetermined time threshold has elapsed, a predetermined reconstruction column coordinates reconstructing data storage locations within the reconstruction column. For a second row in the array, a predetermined coordinating column coordinates the execution of a received memory access requests from the client corresponding to the second row. In this manner, a column coming back online after a failure is able to repair without halting the servicing of read and write requests.

The storage subsystem comprises data storage locations addressable as rows and columns in an array. Each column comprises a separate storage device. Each row includes redundant data. For a given row, a coordinating storage device receives data from the client, coordinates computation and storage of redundant data, and forwards data to other storage devices. In response to receiving data targeted for storage in a given storage location, a non-volatile, temporary storage device that is associated with the separate storage device that includes the given storage location buffers the received data. The coordinating storage device conveys a write completion message to the client in response to detecting that the data has been buffered in the non-volatile, temporary storage devices. At least two storage devices are coordinating storage devices in separate rows.

摘要： Information identifying the inode of the parent directory of a file may be stored in that file's inode. A reverse pathname lookup from the file's inode identifier may be performed by reading a parent directory inode identifier of the file's parent directory from the file's inode and using the parent directory inode identifier to generate a pathname for the file. Generating the pathname may involve identifying the filename of the file by searching the parent directory identified by the parent inode identifier for the file's filename. A file's inode may include more than one parent directory inode identifier.

摘要： Various methods and systems for securing access to hash-based storage systems are disclosed. One method involves receiving information to be stored in a storage system from a storage system client and then generating a key. The key identifies the information to be stored. The value of the key is dependent upon a secret value, which is associated with the storage system. The key is generated, at least in part, by applying a hash algorithm to the information to be stored. The key can then be returned the key to the storage system client. The storage system client can then use the key to retrieve the stored information.

摘要： Various methods and systems for updating a search engine index based on a file change log are disclosed. One method involves accessing a file, which stores a file change log maintained by a file system. The file change log identifies one or more recently modified files. The method also involves updating an index, based on a recently-modified file identified in the file change log. The index is used to search files maintained by the file system. An application external to the file system accesses the file storing the file change log and updates the index.

摘要： A method and mechanism for managing a time-indexed block map in a file system configured to store multiple versions of file data. A file system includes inodes or other structures corresponding to files in the system. Responsive to creating a file, one or more blocks are allocated for use in storing the file data. A block map is maintained for the file and is updated to include an identification of the blocks storing the file data and a timestamp corresponding to the stored data. In response to creating a file, data corresponding block map is maintained. In addition, a new entry is created in the block map which identifies the newly allocated blocks. Further, an entry of the block map is updated to (i) identify the particular blocks to which the write was directed and (ii) include a timestamp corresponding to the time of the write.
