AI Technical Summary

Technical Problem

Existing CIFS file locking methods rely on full scans and retransmissions to restore the lock state after server failures, resulting in a time-consuming recovery process that consumes a lot of network resources, making it difficult to meet the high availability requirements of modern distributed systems.

Method used

By receiving lock operation requests from clients, the lock granularity of the target file is dynamically determined and adjusted based on file access characteristics and lock conflict information. Combined with a distributed consistency protocol, the lock state consistency is maintained, and the lock granularity is optimized to achieve efficient recovery.

Benefits of technology

It significantly improves the recovery efficiency of distributed file system lock management, reduces resource overhead, and meets the high availability and high concurrency access performance requirements of modern distributed systems.

Abstract

This application discloses a file lock management method, apparatus, electronic device, and storage medium, relating to the field of computer technology. Through this application, the lock granularity of the target file can be dynamically determined and adaptively adjusted based on the client's file access characteristics, and the lock granularity can be optimized in real time based on lock conflict information. Simultaneously, the consistency of lock states among multiple file servers in a distributed environment is maintained. Therefore, it can solve the problem of long recovery time and high network resource consumption caused by existing CIFS file lock methods relying on full scans and retransmissions to restore lock states after server failures. This significantly improves the recovery efficiency of distributed file system lock management and reduces resource overhead, thereby meeting the high availability and high concurrency access performance requirements of modern distributed systems.
