A file system is simply a method for storing and organizing computer files and the data the contain to make it easy to find and access them. More formally, a file system is a set of abstract data types that are implemented for the storage, hierarchical organization, manipulation, navigation, access, and retrieval of data.
Veritas File System (VxFS) was the first commercial journaling file system. With journaling, metadata changes are first written to a log (or journal) then to disk. Since changes do not need to be written in multiple places, thougput is much faster as the metadata is written asynchronously.
VxFS major components include :
Loging
Extent
File system disk layouts
