11 | <title>Creating a File System on the Partition</title>
|
---|
12 |
|
---|
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
|
---|
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>
|
---|
22 | file system. Instructions for creating other file systems can be found at
|
---|
23 | <ulink url="&blfs-root;view/svn/postlfs/filesystems.html"/>.</para>
|
---|
24 |
|
---|
25 | <para>To create an <systemitem class="filesystem">ext3</systemitem> file
|
---|
26 | system on the LFS partition, run the following:</para>
|
---|
27 |
|
---|
28 | <screen role="nodump"><userinput>mke2fs -jv /dev/<replaceable><xxx></replaceable></userinput></screen>
|
---|
29 |
|
---|
30 | <para>Replace <replaceable><xxx></replaceable> with the name of the LFS
|
---|
31 | partition (<filename class="devicefile">hda5</filename> in our previous
|
---|
32 | example).</para>
|
---|
33 |
|
---|
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>
|
---|
41 |
|
---|
42 | <screen role="nodump"><userinput>debugfs -R feature /dev/<replaceable><xxx></replaceable></userinput></screen>
|
---|
43 |
|
---|
44 | <para>If the output contains features other than
|
---|
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>
|
---|
52 |
|
---|
53 | <screen role="nodump"><userinput>cd /tmp
|
---|
54 | tar -xjvf /path/to/sources/e2fsprogs-&e2fsprogs-version;.tar.bz2
|
---|
55 | cd e2fsprogs-&e2fsprogs-version;
|
---|
56 | mkdir -v build
|
---|
57 | cd build
|
---|
58 | ../configure
|
---|
59 | make #note that we intentionally don't 'make install' here!
|
---|
60 | ./misc/mke2fs -jv /dev/<replaceable><xxx></replaceable>
|
---|
61 | cd /tmp
|
---|
62 | rm -rfv e2fsprogs-&e2fsprogs-version;</userinput></screen>
|
---|
63 | </note>
|
---|
64 |
|
---|
65 | <para>If you are using an existing <systemitem class="filesystem">swap
|
---|
66 | </systemitem> partition, there is no need to format it. If a new
|
---|
67 | <systemitem class="filesystem"> swap</systemitem> partition was created,
|
---|
68 | it will need to be initialized with this command:</para>
|
---|
69 |
|
---|
70 | <screen role="nodump"><userinput>mkswap /dev/<replaceable><yyy></replaceable></userinput></screen>
|
---|
71 |
|
---|
72 | <para>Replace <replaceable><yyy></replaceable> with the name of the
|
---|
73 | <systemitem class="filesystem">swap</systemitem> partition.</para>
