摘要: 提出了一种管理层数据热备份的高可靠文件系统.与传统的高可靠文件系统不同，提出的高可靠文件系统对管理层数据进行了热备份，能够避免因管理层数据损坏导致的文件系统崩溃，该文件系统能够动态检测管理层数据的完整性，当发生因单粒子翻转或物理器件损坏引起的管理层数据损坏时，实时切换到备份的管理层数据，能够保证高可靠文件系统的无缝切换和运行.Abstract: In this paper,we propose a high-reliable file system,which hot backups its own management data.With the difference from traditional works,the file system proposed here can avoid the crash by the damage of management data.It detects the damage of management data dynamically,and switches to the backup one when the damage of management data happens,leading to continuum of the file system.
