Abstract
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.
