A.9.5 Linux Ext2

Ext2, one of the main file systems for the Linux operating system, is a 32-bit file

system. Its maximum size is 16 Terabytes. The main data structure that describes

a file is an INODE. A place to store the table of all INODEs has to be allocated in

advance (during formatting).Linux Ext3

Officially introduced with Red Hat Linux version 7.2, Ext3 is the Red Hat

journaling file system. It is forward- and backward-compatible with Linux ext2.

It has multiple journaling modes and broad, cross-platform compatibility in both

32- and 64-bit architectures.

A.9.6 Linux ReiserFS

ReiserFS was officially introduced to Linux in 2001. ReiserFS overcomes many

Ext2 disadvantages. It is a 64-bit journaling file system that dynamically allocates

space for data substructures.
