Tracking Data Slices Affected By Changing A Decentralized Storage Protocol

Abstract:

A method for execution by a computing device includes changing a decentralized agreement protocol (DAP) of a storage network to a new DAP, where storage units of the storage network store encoded data slices. The method further includes performing, based on the changing, a DAP redistribution operation that is associated with transfer of affected ones of the encoded data slices from at least one storage unit to at least one other storage unit. The method further includes maintaining, based on the changing, at least one source name address map that includes a listing of source names in accordance with storage network addresses for the at least one storage unit. The method further includes updating the at least one source name address map based on performance of the transfer of the affected ones and storing the updated at least one source name address map in a memory of the storage network.
