Some Notable Reliability Techniques for Disk File Systems
File system operations include data operations and metadata operations. Data operations act upon actual user data while metadata operations modify the structure of the file system, like creating, deleting, or renaming files, directories, etc. During a metadata operation, the system must ensure that data are written to disk in such a way that the file system can be recovered to a consistent state after a system crash. In this paper we look at some most notable techniques which ensure reliability of disk file systems against system crashes and failures.
