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
data.
data.
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
partition.
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.
