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
