Retry method, device and equipment of storage system, storage medium and program product

Abstract

Embodiments of the present application provide a retry method, device and equipment of a storage system, a storage medium and a program product. The method comprises: obtaining a token bucket state of a first device, the token bucket state being used to indicate parameters related to a flow limiting strategy of a storage system of the first device; constructing a dynamic state model according to the token bucket state, the dynamic state model being used to indicate a dynamic service state of the storage system; in response to a flow limiting error indication of a first data request sent by the first device, determining a predicted state of the first data request according to the dynamic state model; determining a predicted recovery duration of the storage system according to the predicted state; and resending the first data request to the first device according to the predicted recovery duration. The efficiency of retry is improved.
