Abstract
A method includes issuing write commands to DS storage units regarding encoded data slices. A write command causes a storage unit to store an encoded data slice, but not allow access to the stored encoded data slices. The method includes receiving write acknowledgements from at least some of DS storage units to produce received write acknowledgements. The method includes, when a write threshold number of the received write acknowledgements have been received within a given time frame, issuing commit commands to the DS storage units. A commit command causes the storage unit to allow access to the stored encoded data slice. The method includes, when the write threshold number of the received write acknowledgements have not been received within the given time frame, issuing rollback commands to the DS units. A rollback command causes the storage unit to continue to not allow access to the stored encoded data slice.
