The purpose of the present application is to provide a method and a device for performing startup check on a computing device in a distributed storage system. Compared with the prior art, in the startup process of a computing device in a distributed storage system, the technical scheme of the present application performs startup check on the computing device, and performs corresponding processingon the startup process of the computing device according to a corresponding check result; the technical scheme performs the startup check before the distributed storage system starts, standardizes thesoftware and hardware requirements of the distributed storage system, avoids major failures after the distributed storage system starts, and improves the stability and performance of the distributedstorage system; and furthermore, the technical scheme performs corresponding processing on the startup process of the computing device according to the corresponding check result and security level information of the startup check, the startup is not allowed when the severely affected check result is discovered, and alarm processing is performed when the secondary affected check result is discovered.
