Research on Reliable Management Methods of File Systems
Aimed at solving the reliability problem of file systems in the event of sudden power outages,a reliable management method for file systems is researched.It adopts metadata transaction management technology,using write time copy technology to achieve remote updates during data updates.It uses PING-PONG log management technology,maintaining two-level logs for file system space and node allocation,and maintaining two transaction point log records.Redundant storage of critical data is managed through logical volumes to prevent the system from being unable to start normally due to the destruction of super block data during power outages.Testing has been shown that this method can solve the consistency prob-lem of file system status in case of sudden power outage,and achieve reliable management of file systems.
