Embodiments of the present disclosure provide a method, a device and a computer program product for managing a storage system. A method of managing a storage system comprises: determining whether a response time of a file system operation occurring in the storage system exceeds a first predetermined threshold, wherein the storage system comprises at least a memory and a plurality of storage devices and wherein the file system operation synchronizes data stored in the memory to at least one storage device from the plurality of storage devices. The method comprises: in response to the response time exceeding the first predetermined threshold, obtaining trace information related to the file system operation. In addition, the method further comprises determining, by analyzing the trace information, one or more factors that cause timeout of the file system operation. Embodiments of the present disclosure are capable of automatically determining a cause for the timeout of the file system operation in the storage system, thereby improving the management efficiency of the storage system.
