Missing slice reconstruction in a dispersed storage network
Abstract:
A method for execution by a processing system of a dispersed storage network includes receiving first slices encoded via a first information dispersal algorithm (IDA) in a response to an access request corresponding to an associated data object and determining when a number of the first slices is less than a read threshold corresponding to the first IDA and that the data object is also encoded into second slices via a second IDA. If so, the processing system identifies missing slices encoded via the first IDA corresponding to the access request; determines at least one of the second slices encoded via the second IDA corresponding to the missing slices; retrieves the at least one of the second slices; and generates the data object based on the first slices encoded via the first IDA and the at least one of the second slices encoded via the second IDA.
