<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 journalling
|
|
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
|
|
<ulink url="&blfs-root;view/svn/postlfs/filesystems.html"/>.</para>
|
|
|
|
<para>To create an <systemitem class="filesystem">ext3</systemitem> file
|
|
system on the LFS partition, run the following:</para>
|
|
|
|
<screen role="nodump"><userinput>mke2fs -jv /dev/<replaceable><xxx></replaceable></userinput></screen>
|
|
|
|
<para>Replace <replaceable><xxx></replaceable> with the name of the LFS
|
|
partition (<filename class="devicefile">hda5</filename> in our previous
|
|
example).</para>
|
|
|
|
<note>
|
|
<para>Some host distributions use custom features in their filesystem
|
|
creation tools (E2fsprogs). This can cause problems when booting into your new
|
|
LFS in Chapter 9, as those features will not be supported by the LFS-installed
|
|
E2fsprogs; you will get an error similar to <quote>unsupported filesystem
|
|
features, upgrade your e2fsprogs</quote>. To check if your host system
|
|
uses custom enhancements, run the following command:</para>
|
|
|
|
<screen role="nodump"><userinput>debugfs -R feature /dev/<replaceable><xxx></replaceable></userinput></screen>
|
|
|
|
<para>If the output contains features other than
|
|
<option>has_journal</option>, <option>ext_attr</option>,
|
|
<option>resize_inode</option>, <option>dir_index</option>,
|
|
<option>filetype</option>, <option>sparse_super</option>,
|
|
<option>large_file</option> or <option>needs_recovery</option>, then your
|
|
host system may have custom enhancements. In that case, to avoid later
|
|
problems, you should compile the stock E2fsprogs package and use the
|
|
resulting binaries to re-create the filesystem on your LFS partition:</para>
|
|
|
|
<screen role="nodump"><userinput>cd /tmp
|
|
tar -xjvf /path/to/sources/e2fsprogs-&e2fsprogs-version;.tar.bz2
|
|
cd e2fsprogs-&e2fsprogs-version;
|
|
mkdir -v build
|
|
cd build
|
|
../configure
|
|
make #note that we intentionally don't 'make install' here!
|
|
./misc/mke2fs -jv /dev/<replaceable><xxx></replaceable>
|
|
cd /tmp
|
|
rm -rfv e2fsprogs-&e2fsprogs-version;</userinput></screen>
|
|
</note>
|
|
|
|
<para>If you are using an existing <systemitem class="filesystem">swap
|
|
</systemitem> partition, there is no need to format it. If a new
|
|
<systemitem class="filesystem"> swap</systemitem> partition was created,
|
|
it will need to be initialized with this command:</para>
|
|
|
|
<screen role="nodump"><userinput>mkswap /dev/<replaceable><yyy></replaceable></userinput></screen>
|
|
|
|
<para>Replace <replaceable><yyy></replaceable> with the name of the
|
|
<systemitem class="filesystem">swap</systemitem> partition.</para>
