However, the kernel module added by this method can only be executed in the kernel mode. If the process processing of the added kernel module is abnormal, the shutdown process will be blocked; in addition, if the added kernel module performs the operation before shutdown, the process of the user mode application has exited, this method cannot handle the exception handling requirements of the user-mode application before shutting down

The present application provides a shutdown processing method and device, which are applied to a server, and the server includes a kernel and a user mode application program. Whether the first state information about shutdown is confirmed. When it is confirmed that the value of the first state information is used to indicate that the server is about to shut down, then perform the operation that the user state application program needs to process; after performing the operation, modify the first The value of the second state information in the second state file, so that the modified value is used to indicate that the operation has been completed; the kernel queries the second state information, and when it is confirmed that the value of the second state information is used to indicate the user mode application When the program completes the operations that need to be processed, it executes a shutdown process to complete the shutdown operation of the server. In this way, it is realized that the user-mode application program completes the operations to be performed before shutting down, and the shutting down process will not be blocked.
Description
technical field [0001] The present application relates to the field of computer communication technologies, and in particular, to a shutdown processing method and device. Background technique [0002] With the popularization of computer technology, the degree of informatization of daily work in society is gradually improving. Especially in the field of enterprise and public applications, user-mode applications based on general server architecture are becoming more and more abundant. Typically, the programs of the enterprise application system are usually distributed on one or more servers. When the server is shut down, the user-mode applications running on it often cannot sense it in time, or cannot complete what needs to be done before the system shuts down. For example, IO exceptions in a distributed cluster storage system are processed quickly to reduce the impact of a single node exit on the performance of the entire cluster system. In this way, before the server is sh...
