Method, device and equipment for adaptively modifying erasure redundancy rule and medium

The invention provides a method, device and equipment for adaptively modifying an erasure redundancy rule and a readable medium. The method comprises the following steps: setting the number of adaptive erasure data blocks in a cluster; monitoring the state of each node in the cluster, and counting the number of fault nodes and the number of non-fault nodes; comparing the number of fault nodes with the number of verification blocks, comparing the number of non-fault nodes with the sum of the number of data blocks and the number of verification blocks, and comparing the number of non-fault nodes with the sum of the number of adaptive erasure data blocks and the number of verification blocks; and judging whether to change the erasure redundancy rule or not according to different comparison results. By using the scheme provided by the invention, the requirement of a customer on the security of the stored data can be met, the service interruption caused by data damage can be reduced, the service continuity is ensu
