File System Types in AIX
File systems represent a convenient way to store and access data from a logical volume. A file system is comprised of files, directories, and other data structures. File systems maintain information and identify the location of a file or directory's
File system types
The following types of file systems are supported on an AIX 5L Version 5.3:
Journaled file system
This type of file system is named journaled because the system uses journaling techniques to maintain the integrity of control structures. Each journaled file system must reside on a distinct jfs logical volume. Therefore, the file system size will be a multiple of the size of a logical
Enhanced journaled file system
This is the enhanced version of the initial journalized file system. It uses extent based allocation to allow higher performance, larger file systems, and a larger file size. Each enhanced journaled file system must reside on a distinct jfs2 logical volume. When the operating system is
installed using the default options, it creates JFS2 file systems.
Network file system
The network file system (NFS) is a distributed file system that allows users to access files and directories located on remote computers and use those files and directories as though they are local.
CD-ROM file system
The CD-ROM file system (CDRFS) is a file system type that allows you to access the contents of a CD-ROM through the normal file system interfaces.
