DISTRIBUTION OF DATA ON DISTRIBUTED STORAGE SYSTEM

PROBLEM TO BE SOLVED: To provide a data distribution method that allows a user to use a distributed storage system even if a part of the distributed storage system is in a maintenance period.SOLUTION: The method for distributing data includes a step of receiving a file in a non-transitory memory (802), a step of splitting the received file into chunks using a computer processor which communicates with the non-transitory memory (804), and a step of distributing the chunks to storage devices of a distributed storage system based on a maintenance hierarchy of the distributed storage system (806). The maintenance hierarchy includes maintenance units, each of which has an active state and an inactive state. Further, the individual storage devices are associated with the maintenance units. In order to maintain file accessibility of files when the maintenance units are in an inactive state, the chunks are distributed to a plurality of maintenance units.SELECTED DRAWING: Figure 8
