    摘要： A method begins by a dispersed storage (DS) processing module receiving a request to copy a data object in a dispersed storage network (DSN). The method continues with the DS processing module identifying one or more sets of at least a decode threshold number of slice names for one or more sets of encoded data slices of the data object and generating one or more sets of at least a decode threshold of new slice names. The method continues with the DS processing module sending the one or more sets of at least a decode threshold of new slice names to storage nodes of the DSN and instructing the storage nodes to link the one or more sets of at least a decode threshold of new slice names to the one or more sets of encoded data slices thereby producing a non-replicated copy of the data object.

    摘要： A method begins by a processing module detecting a potential dispersed storage network (DSN) protocol issue that effects access of dispersed storage error encoded data within a DSN. The method continues with the processing module identifying a DSN entity based on the DSN protocol issue and generating a DSN protocol inquiry frame. The method continues with the processing module transmitting the DSN protocol inquiry frame to the DSN entity. The method continues with the processing module receiving a DSN protocol response frame from the DSN entity and resolving the DSN protocol issue based on the DSN protocol response frame.

    摘要： A method begins by a processing module receiving a data storage request, wherein the data storage request includes data and a data identifier (ID). The method continues with the processing module dispersed storage error encoding the data to produce a set of encoded data slices and determining a data dispersed storage network (DSN) address. The method continues with the processing module sending the set of encoded data slices to a DSN memory for storage at the data DSN address and updating a directory file with path information corresponding to the data ID and the data DSN address to produce an updated directory file. The method continues with the processing module dispersed storage error encoding the updated directory file to produce a set of encoded updated directory slices and sending the set of encoded updated directory slices to the DSN memory for storage at a directory DSN address.

    摘要： A method begins by a processing module dispersed storage error encoding data to produce a set of encoded data slices and generating a transaction identifier regarding storage of the set of encoded data slices. The method continues with the processing module outputting a plurality of write request messages to a plurality of dispersed storage (DS) units, wherein each of the plurality of write request messages includes the transaction identifier and a corresponding one of the set of encoded data slices. The method continues with the processing module receiving write response messages from at least some of the DS units, wherein each of the write response messages includes a reference to the transaction identifier. The method continues with the processing module updating directory information regarding storage of the data to produce updated directory information when at least a write threshold number of the write response messages have been received.

    摘要： A method begins by a processing module dispersed storage error encoding data to produce encoded data slices and updating directory metadata regarding storing the data in a dispersed storage network (DSN) memory to produce updated directory metadata. The method continues with the processing module dispersed storage error encoding the updated directory metadata to produce encoded directory metadata slices and transmitting one or more data slice write requests to the DSN that each include a first transaction number. The method continues with the processing module transmitting one or more directory metadata write requests to the DSN memory, wherein the one or more directory metadata write requests includes a second transaction number, and when a favorable write response condition exists, transmitting a commit request to the DSN memory to commit storage of at least one of: the encoded data slices and the encoded directory metadata slices.
