More Information
Summary:The invention discloses a node repairing method, device and equipment and a readable storage medium, and the method is applied to repairing a request node, and comprises the steps: obtaining the expected downloading time and the expected uploading time corresponding to each stripe node in a plurality of stripe nodes; determining a repair node from the plurality of stripe nodes according to the expected downloading time and the expected uploading time; allocating the to-be-allocated stripe repair task to a repair node; according to the invention, the strip repair is taken as a basic unit, and the network transmission time of the strip during repair on each strip node is compared based on the greedy algorithm, so that the strip node with the minimum network transmission time can be selected as the repair node of the strip, and a plurality of strips can be uniformly distributed on different strip nodes to be repaired; therefore, the bandwidth use of each strip node is relatively balanced, the network transmissio
