The Linux ext3 file system is the default system in many linux derivatives. It allows for journalling, which the ext2 system did not. It also allows in-situ upgrades without asking for a backup first.

What is the default file system type in SLES?
ext3.
Why are Linux partitions ext3?
Not all Linux partitions are ext3. It just happens to be the most popular file system. ext3 was created especially for Linux, so it is free from any patent issues involved with some other file systems.
What file system does Red Hat Enterprise Linux use?
ext3 is the default file system for Red Hat Enterprise Linux.
What is the primary file system used by Fedora 12?
The primary file system for Fedora 12 is ext4 but you may also use ext3.
How do you create an ext3 partition?
You would have to create a partiotion using fdisk or some other partition program. then you can format it for ext3 file system sudo mkfs.ext3 /dev/sda1
What file system does Ubuntu or Debian use?
By default it should be using the ext3 file system, but you have a choice of several, including ext2, reiserfs, etc. Newer versions of Ubuntu tend to install as ext4 file systems, however if you've upgraded from an older version then you'll keep your original file system.
What software do you need to write files to a Linux ext2 or ext3 file system from Windows XP?
There are a couple different IFS (Installable File System) drivers that can be used to do this. Links to them are posted in the "Related links" section below.
What is the ext2 file system?
The ext2 file system was a common file system for Linux systems. It has been supplanted for the most part by ext3 and ext4, which are backwards-compatible with it. It is still used on USB drives since it is not journaled, reducing the number of writes made to the drive (but thus increasing corruptibility).
What is the Ext4?
Ext4 (fourth extended filesystem) is file system used in Linux and it was introduced as the successor to ext3. Ext 4 is a deeper improvement over ext3, many of them was originally developed by Cluster file system from 2003 to 2006, aiming to extend storage limitation and improving performance. But some developer of Linux kernel did not accept extensions to ext3 for the reason of stability. They advised to fork the ext3's source code and rename it as ext4. Then the ext3 filesystem maintainer announced the new plan of ext4 in 2006. In the year 2008, the ext4 file system was released, which is contained in Linux 2.6.28. Ext4 filesystem is an improved design with better performance, reliability and features. The follow part talks about several main features of ext4 file system.Backward compatibility. Ext4 filesystem is backward compatible with ext3 and ext2. Ext 3 filesystem can be migrated to ext4 with the help of several commands in read-only mode. Thus you can convert ext3 to ext4 without reformatting or reinstalling operating system. But you cannot go back to ext3 once it is has upgraded to ext4.Journal checksumming. Journal is one of the most used parts of the disk, which makes block that form part of it more prone to hardware failure. Sine recovering from corrupted journal can cause massive corruption, ext4 checksums the journal data to make sure whether journal blocks are corrupted. Besides, it is able to safely avoid disk I/O waiting during journaling, improving performance.Larger filesystem / file size. Ext3 supports 16TB maximum filesystem size and 2TB maximum file system, while ext4 can support up to 1EB (1EB = 1024PB = 1024*1024TB =1024*1024 GB) file system size and 16TB of maximum file size, as ext4 adds 48-bit block addressing. 1EB = 1024PB = 1024*1024TB =1024*1024 GB
What are the 3 most popular Native Linux File Systems?
ext2, ext3, ReiserFS, are some native file systems
What file is used on a Linux system?
Linux systems have access to a wide range of filesystems, however most Linux distributions default to ext3 or ext4. In the future it is our hope that the "standard" Linux filesystem will be btrfs.Linux supports many different file systems, including ext, ext3, ext4, ReiserFS, Reiser4, JFS, btrfs, and XFS.
Does ext3 provide journaling in Linux?
Yes,ext3 provide journaling in linux. there are 3 types of journaling provided by ext3 1) Journal-full journal mode,all data can be recovered. 2) Writeback-it only recover metadata(data about data),corrupted file can not be stored. 3) Ordered-recover metadata and specific file data.
