摘要： A distributed storage integrity system in a dispersed storage network includes a scanning agent and a control unit. The scanning agent identifies an encoded data slice that requires rebuilding, wherein the encoded data slice is one of a plurality of encoded data slices generated from a data segment using an error encoding dispersal function. The control unit retrieves at least a number T of encoded data slices needed to reconstruct the data segment based on the error encoding dispersal function. The control unit is operable to reconstruct the data segment from at least the number T of the encoded data slices and generate a rebuilt encoded data slice from the reconstructed data segment. The scanning agent is located in a storage unit and the control unit is located in the storage unit or in a storage integrity processing unit, a dispersed storage processing unit or a dispersed storage managing unit.

摘要： A distributed storage network receives a data object and determines a size of the data object. The network then determines whether the data object should be segmented into fixed size segments or variable sizes segments based upon some variable-length algorithm. If the fixed approach is selected, the data object is segmented into two or more fixed size segments with attached header information and the information is further processed using error coding dispersal storage functions within the network. If the variable approach is selected, the data object is segmented into two or more variable-sized segments with attached header information and the information is further processed using error coding dispersal storage functions within the network. Both the variable and fixed approaches enable storage of error-correctable data slices in a distributed storage manner.

摘要： A distributed storage network contains a user device that has a computing core, a DSN interface and either an integrated or an externally-connected camera or sensor. The camera or sensor collects data from its surrounding environment and processes the data at least partially through error coding dispersal storage functions that include slicing the data into a plurality of error-coded data slices. The error-coded data slices are output by the user device for one or more of storage within a dispersed storage network (DSN) memory, playing on a destination player, or broadcast consumption over a network. A storage integrity unit manages the storage capacity, use, and/or throughput of the system to ensure that data is processing in a real time or near real time so that data can be accurately processed and perceived by targeted end users.

摘要： A computer a network interface and a central processing unit. The network interface communicates with a network. The central processing unit (CPU) is operable to receive a networked file system access request packet and to identify a root directory based on the networked file system access request packet. The CPU then identifies a file directory based on the root directory and the networked file system access request packet. The CPU then identifies file object metadata based on the file directory and identifies a set of slice servers based on the file object metadata and the networked file system access request packet. The CPU then issues, via the network interface, a set of commands to a set of slice servers regarding the networked file system access request packet.

摘要： A storage integrity system in a dispersed storage network scans an address range of data slices to identify errors in one of a plurality of encoded data slices, wherein the plurality of encoded data slices are generated from a data segment using an error encoding dispersal function. When the storage integrity system detects an error, it identifies one of the encoded data slices for rebuilding. The identified data slice is rebuilt in response to the type of error. For example, when the type of the error includes a temporary error, the storage integrity system waits a predetermined time period to determine whether the error still exists prior to rebuilding the identified data slice.

The method continues by receiving a commit acknowledgement from a DS storage unit of the plurality of DS storage units to produce a received commit acknowledgement. The method continues by issuing a plurality of finalize commands to the plurality of DS storage units when a write threshold number of the received commit acknowledgements have been received.

摘要： Multiple revisions of an encoded data slice are generated, with each revision having the same slice name. Each of the data slices represents the same original data portion, but each is encoded so that no single data slice can be used to reconstruct the original data portion. Appropriate revision numbers are associated with each encoded data slice, and the encoded data slices and associated revision numbers are transmitted for storage in selected storage units of a distributed storage network. If write confirmations are received from at least a write threshold number of storage units, a commit command is transmitted so that the most recently written data slices will be available for access. After a commit command is issued, a current directory used to access the encoded data slices can be sliced, encoded, and stored in the same way as the data slices.
