摘要： A method includes issuing write commands to DS storage units regarding encoded data slices. A write command causes a storage unit to store an encoded data slice, but not allow access to the stored encoded data slices. The method includes receiving write acknowledgements from at least some of DS storage units to produce received write acknowledgements. The method includes, when a write threshold number of the received write acknowledgements have been received within a given time frame, issuing commit commands to the DS storage units. A commit command causes the storage unit to allow access to the stored encoded data slice. The method includes, when the write threshold number of the received write acknowledgements have not been received within the given time frame, issuing rollback commands to the DS units. A rollback command causes the storage unit to continue to not allow access to the stored encoded data slice.
摘要翻译：一种方法包括向DS存储单元发出关于编码数据片的写入命令。写命令使存储单元存储编码数据片，但不允许访问存储的编码数据片。该方法包括从至少一些DS存储单元接收写入确认以产生接收到的写入确认。该方法包括：当在给定时间帧内接收到所接收的写入确认的写入阈值数量时，向DS存储单元发出提交命令。提交命令使存储单元允许访问存储的编码数据片。该方法包括：当在给定时间帧内尚未接收到接收到的写入确认的写入阈值数量时，向DS单元发出回滚命令。回滚命令使存储单元继续不允许访问存储的编码数据切片。

摘要： A dispersed storage (DS) method begins by issuing a plurality of write commands to a plurality of DS storage units. The method continues by receiving a write acknowledgement from one of the plurality of DS storage units to produce a received write acknowledgement. The method continues by issuing a plurality of commit commands to the plurality of DS storage units when a write threshold number of the received write acknowledgements have been received. 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： A distributed storage network generates a plurality of data segments from a data object and stores each of the plurality of data segments as a plurality of encoded data slices generated from an error encoding dispersal function. When the distributed storage network receives a modification request for the data object, it determines a size of the plurality of data segments of the data object from a segment size field and identifies one of the plurality of data segments requiring modification. The identified data segment is reconstructed from the plurality of encoded data slices and modified in accordance with the modification request.

摘要： A method begins with a processing module determining that storage of data requires updating, wherein the data is stored as a plurality of sets of encoded data slices in DSN memory. For a first type of updating, the processing module increases the total number while maintaining the decode threshold number. The processing module then, for each set of encoded data slices, creates another encoded data slice in accordance with the dispersed storage error encoding function and the increased total number and sends the new encoded data slices to the DSN memory. For a second type of updating, the processing module increases the total number and the decode threshold number. The processing module then recovers the data and encodes it in accordance with the dispersed storage error encoding function using the increased total number and the increased decode threshold number to produce an updated plurality of sets of encoded data slices.

摘要： A method for execution by one or more processing modules of a dispersed storage network (DSN) includes receiving a data access request for at least one data segment stored in the DSN. A vault associated with data access request is identified along with one of a plurality of sub-vaults associated with the vault. Access information corresponding to the one of the plurality of sub-vaults is retrieved to determine whether the access request is allowed. When the access request is allowed, a sub-vault directory associated with the one of the plurality of sub-vaults is retrieved to identify a DSN address corresponding to the data access request, and fulfilling the data access request based on the DSN address.

摘要： A method begins by a processing module of a computing device receiving a most current revision value for a data element, where a revision value for the data element is generated based on a current time of a storing device. The method continues with the processing module generating a new revision value for a currently revised version of the data element based on a current time of the computing device and comparing the current time of the new revision value with the current time of the most current revision value. When the current time of the new revision value precedes the current time of the most current revision value, the method continues with the processing module adjusting the new revision value to produce an adjusted revision value and facilitating storage of the currently revised version of the data element having the adjusted revision value.
