Abstract

The invention provides a distributed file lock fault processing method and a system, a terminal and a storage medium. The method comprises the following steps: establishing a network state monitoringinteraction chain between a local end and an opposite end; receiving fault restart information sent by the opposite terminal locally through the monitoring interaction link after fault restart of theopposite terminal; and triggering a local file lock management protocol by the fault restart information, and restarting local and opposite file locks by utilizing the file lock management protocol. According to the method, data consistency is guaranteed, concurrent access of multiple clients and stability of the system are supported, after one party is restarted due to a fault, the authorized file lock is immediately recovered, and the situation that the file is lost due to the fact that operation is interrupted is avoided.

Description

technical field [0001] The invention relates to the technical field of distributed file systems, in particular to a distributed file lock fault handling method, system, terminal and storage medium. Background technique [0002] At present, as enterprise data becomes larger and larger, users have higher and higher requirements for data transmission performance and stability. The storage server will have a large number of clients, and multiple clients will simultaneously access files on the server. It is bound to cause file conflicts, and the cooperation of various clients to ensure the consistency of file data has become the focus of attention of software users and developers. Therefore, how to provide an efficient, reliable, easy-to-implement and maintain, and highly consistent network file system file lock is particularly important. [0003] File lock is a mechanism. In a multitasking operating system environment, if a process tries to write to a file that is being read by...
