摘要： A method begins by processing module determining data to migrate, wherein the data is stored as a plurality of sets of encoded data slices in a first set of dispersed storage (DS) units. The method continues with the processing module retrieving at least a read threshold number of encoded data slices for each set of the plurality of sets of encoded data slices and dispersed storage error decoding the at least the read threshold number of encoded data slices in accordance with error coding dispersal storage function parameters to reproduce the data. The method continues with the processing module dispersed storage error encoding the data in accordance with second error coding dispersal storage function parameters to produce a plurality of sets of second encoded data slices and sending at least a write threshold number of second encoded data slices to a second set of DS units for storage therein.

摘要： Multiple revisions of an encoded data slice can be stored in a distributed storage unit. Before writing a new revision of an encoded data slice to storage, the distributed storage unit can invoke a write lock for all encoded data slices having the same slice name as the slice being currently written. The slice being currently written can be stored in temporary storage, and a rollback timer started. If a commit command is received before expiration of the rollback timer, the currently written slice can be permanently stored and made accessible for read requests. If the rollback timer expires prior to the storage unit receiving a commit command, however, a previously stored revision will be used.
摘要翻译：编码数据切片的多个修订可以存储在分布式存储单元中。在将编码数据切片的新版本写入存储之前，分布式存储单元可以调用具有与当前写入的切片相同的切片名称的所有编码数据切片的写入锁定。当前写入的片可以存储在临时存储器中，并且回滚定时器开始。如果在回滚定时器到期之前接收到提交命令，则可以永久存储当前写入的片段，并使读取请求可访问。但是，如果回滚定时器在存储单元接收到提交命令之前到期，则将使用先前存储的版本。

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 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.
