The primary objective of DATA storage systems is to persist data PERMANENTLY (or at least until specifically destroyed). But hardware is imperfect, disks fail, servers crash, which leads to inconsistencies in the file-system metadata. The traditional ways to deal with errors require the system to go offline – not a PLEASANT scenario.

Traditionally, each operating system has its own flavor of storage software architecture, including file systems, to address the challenge. File systems make sure that a user's data is accessible under a user-defined name-space on underlying disk(s). UFS, ext2, NTFS, xfs, and VxFS are some file-system examples.
