<title>Creating a File System on the Partition</title>

- <para>Now that a blank partition has been set up, the file system can be created.
|
|
|
- The most widely-used system in the Linux world is the second extended file
|
|
|
- system (<systemitem class="filesystem">ext2</systemitem>), but with newer
|
|
|
- high-capacity hard disks, journaling file systems are becoming increasingly
|
|
|
- popular. The third extended filesystem (<systemitem
|
|
|
- class="filesystem">ext3</systemitem>) is a widely used enhancement to
|
|
|
- <systemitem class="filesystem">ext2</systemitem>, which adds journaling
|
|
|
- capabilities and is compatible with the E2fsprogs utilities.
|
|
|
- We will create an <systemitem class="filesystem">ext3</systemitem>
|
|
|
- file system. Instructions for creating other file systems can be found at

|
|

|
|
|
