    摘要： A method begins by a dispersed storage (DS) processing module storing a data portion in a dispersed storage network (DSN), where the data portion is associated with a set of data index keys, a version index key, and with a set of portion index keys. The method continues with the DS processing module traversing, based on the set of data index keys, a plurality of index structures to determine whether an object retrieval structure exists for the data portion. When the object retrieval structure exists, the method continues with the DS processing module updating the object retrieval structure by determining whether a version record exists that corresponds to the version index key and when the version record exists, creating, within the version record, a new data portion record for the data portion to include an identifier of the data portion and the set of portion index keys.

    摘要： A method begins by a processing module of a dispersed storage network (DSN) ascertaining a decode threshold value for dispersed storage error encoding data for storage in storage units of the DSN. The method continues with the processing module determining a total width value for the dispersed storage error encoding based on the decode threshold value, a number of selected sites within the DSN, and a number of selected storage units of the selected sites. The method continues with the processing module determining logical storage slots within the selected storage units based on the total width value, the number of selected, and the number of selected storage units. The method continues with the processing module writing a set of encoded data slices to a total width value of the logical storage slots within at least some of the selected storage units of the selected sites based on a slice-to-slot mapping.

    摘要： A method begins by a dispersed storage (DS) processing detecting unavailability of a storage device of a site of dispersed storage network (DSN) memory to produce an unavailable storage device. The method continues with the DS processing module reassigning a fraction of a logical address sub-range of the unavailable storage device to one or more other storage devices, rebuilding one or more logically addressable data objects to produce one or more rebuilt data objects and storing the one or more rebuilt data objects in the one or more other storage devices. When the unavailable storage device becomes available, the method continues with the DS processing module reallocating the fraction of the logical address sub-range from the one or more other storage devices to the storage device and transferring the one or more rebuilt data objects from the one or more other storage devices to the storage device.

    摘要： A method begins generating a plurality of list digest request frames. Each list digest request frames includes a payload section and a protocol header. The payload section includes a start slice name field, an end slice name, and a response count field. The protocol header includes a payload length field and an operation code field to indicate the list digest request operation. The method continues by outputting the list digest request frames to storage units of a dispersed storage network.

    摘要： A method begins by a processing module generating a payload of a dispersed storage network frame regarding a conclusive write request operation by generating one or more slice name fields of a payload to include one or more slice names corresponding to one or more write commit responses of a write request operation, wherein the conclusive write request operation is a conclusive phase of the write request operation. The method continues with the processing module generating one or more slice revision numbering fields of the payload, wherein each slice revision numbering field includes a slice revision number corresponding to an associated slice name of the one or more slice names. The method continues with the processing module generating a protocol header of the DSN frame by generating a payload length field of the protocol header to include a payload length and generating remaining fields of the protocol header.

    摘要： A method begins by a dispersed storage (DS) processing module traversing multiple index structures based on search criteria to identify an object retrieval structure. The method continues with the DS processing module retrieving a set of encoded data slices corresponding to the object retrieval structure from a dispersed storage network (DSN) and decoding the set of encoded data slices in accordance with a dispersed storage error coding function to recover the object retrieval structure. The method continues with the DS processing module identifying one of one or more data version records of the recovered object retrieval structure based on the search criteria to produce an identified data version record and determining DSN addressing information for at least a portion of data based on information of the identified data version record.

    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。
