Abstract:
A method is provided for efficiently recovering information in a distributed storage system where a list of values that should be stored on a storage device is maintained. A first convergence round is scheduled to be performed on the list of values to bring each value to an At Maximum Redundancy (AMR) state. A second convergence round is scheduled to be performed on the list by selecting a wait time interval from a predefined range of wait time intervals between starts of convergence rounds.
