|
---|
[87bae31] | 13 | <para>Now that a blank partition has been set up, the file system can be created.
|
---|
| 14 | The most widely-used system in the Linux world is the second extended file
|
---|
| 15 | system (<systemitem class="filesystem">ext2</systemitem>), but with newer
|
---|
| 16 | high-capacity hard disks, journaling file systems are becoming increasingly
|
---|
[1b737e6] | 17 | popular. The third extended filesystem (<systemitem
|
---|
| 18 | class="filesystem">ext3</systemitem>) is a widely used enhancement to
|
---|
| 19 | <systemitem class="filesystem">ext2</systemitem>, which adds journalling
|
---|
| 20 | capabilities and is compatible with the E2fsprogs utilities.
|
---|
| 21 | We will create an <systemitem class="filesystem">ext3</systemitem>
|
---|
[bb009c9] | 22 | file system. Instructions for creating other file systems can be found at
|
---|
[87bae31] | 23 | <ulink url="&blfs-root;view/svn/postlfs/filesystems.html"/>.</para>

[a92b3e7] | 25 | <para>To create an <systemitem class="filesystem">ext3</systemitem> file
|
---|
[87bae31] | 26 | system on the LFS partition, run the following:</para>

[a92b3e7] | 28 | <screen role="nodump"><userinput>mke2fs -jv /dev/<replaceable><xxx></replaceable></userinput></screen>

[87bae31] | 34 | <note>
|
---|
| 35 | <para>Some host distributions use custom features in their filesystem
|
---|
| 36 | creation tools (E2fsprogs). This can cause problems when booting into your new
|
---|
| 37 | LFS in Chapter 9, as those features will not be supported by the LFS-installed
|
---|
| 38 | E2fsprogs; you will get an error similar to <quote>unsupported filesystem
|
---|
| 39 | features, upgrade your e2fsprogs</quote>. To check if your host system
|
---|
| 40 | uses custom enhancements, run the following command:</para>
|
---|
[d6b76b1] | 41 |
|
---|
[0090db5] | 42 | <screen role="nodump"><userinput>debugfs -R feature /dev/<replaceable><xxx></replaceable></userinput></screen>
|
---|
[d6b76b1] | 43 |
|
---|
[c226182] | 44 | <para>If the output contains features other than
|
---|
[f0fecc7] | 45 | <option>has_journal</option>, <option>ext_attr</option>,
|
---|
| 46 | <option>resize_inode</option>, <option>dir_index</option>,
|
---|
| 47 | <option>filetype</option>, <option>sparse_super</option>,
|
---|
| 48 | <option>large_file</option> or <option>needs_recovery</option>, then your
|
---|
| 49 | host system may have custom enhancements. In that case, to avoid later
|
---|
| 50 | problems, you should compile the stock E2fsprogs package and use the
|
---|
| 51 | resulting binaries to re-create the filesystem on your LFS partition:</para>
