PRIORITIZING REBUILDING OF STORED DATA IN A DISPERSED STORAGE NETWORK

摘要

A method begins by a dispersed storage (DS) processing module of a dispersed storage network (DSN), when in a rebuilding mode, determining a level of rebuilding urgency, where the level of rebuilding urgency is based on an inversely proportional function of a level of error encoded redundancy for error encoded data giving rise to the rebuilding mode. When the level of rebuilding urgency is at or above a critical level, the method continues with the DS processing module placing a set of storage units of the DSN in a critical rebuilding mode, where, when in the critical rebuilding mode, the set of storage units prioritize rebuilding of the error encoded data giving rise to the rebuilding mode over other error encoded data operations.

1. A method for execution by one or more processing modules of one or more computing devices of a dispersed storage network (DSN), the method comprises:
when in a rebuilding mode, determining a level of rebuilding urgency, wherein the level of rebuilding urgency is based on an inversely proportional function of a level of error encoded redundancy for error encoded data giving rise to the rebuilding mode; and when the level of rebuilding urgency is at or above a critical level, placing a set of storage units of the DSN in a critical rebuilding mode, wherein, when in the critical rebuilding mode, the set of storage units prioritize rebuilding of the error encoded data giving rise to the rebuilding mode over other error encoded data operations.
