分布式文件系统一般使用分布式锁管理器技术为系统中的共享资源提供协同访问和一致性视图,并且保证数据并发访问的安全性,避免潜在的数据破坏的危险.本文首先分析了分布式文件系统Lustre分布式锁管理器的基本原理和实现,并针对发生冲突时锁请求的延迟存在的问题提出了改进的方案,它不仅提高了I/O性能,降低访问延迟,而且提高了文件锁服务的可靠性.

Distributed file systems usually use Distributed Lock Manager (DLM) to provide synchronized access and a consistent view for the sharing resource, and protect the data concurrent access security from potentially data corruption. In this paper, it first introduces the principle and implementation of Lustre Distributed Lock Manager (LDLM), and then proposes an improved strategy to resolve the problem of conflicting lock latency. Under the enhanced DLM, it can not only improve the I/O performance and reduce the access latency but also improve the reliability of lock service.
