Abstract:
A method for use in a dispersed storage network operates to select a recovery of selected ones of one or more first sets of encoded data slices in response to detecting a storage error associated with the selected ones of the one or more first sets of encoded data slices; issue requests for a second decode threshold number of encoded data slices of selected ones of one or more second sets of encoded data slices corresponding to the selected ones of the one or more first sets of encoded data slices; decode the second decode threshold number of encoded data slices to produce recovered data in response to receiving the second decode threshold number of encoded data slices; encode the recovered data utilizing first IDA parameters associated with the first IDA to produce one or more rebuilt encoded data slices corresponding to the selected ones of the one or more first sets of encoded data slices; and facilitate storage of the one or more rebuilt encoded data slices.
