Creating a File System on the Partition </h1> </div> <p> 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 (ext2), but with newer high-capacity hard disks, journaling file systems are becoming increasingly popular. We will create an <tt class="systemitem">ext2</tt> file system. Build instructions for other file systems can be found at <a href= "http://www.linuxfromscratch.org/blfs/view/svn/postlfs/filesystems.html"> <i>http://www.linuxfromscratch.org/blfs/view/svn/postlfs/filesystems.html</i></a>. </p> <p> To create an <tt class="systemitem">ext2</tt> file system on the LFS partition, run the following: </p> <pre class="userinput"><kbd class="command">mke2fs /dev/<em class="replaceable"><tt>[xxx]</tt></em></kbd></pre> <p> Replace <em class="replaceable"><tt>[xxx]</tt></em> with the name of the LFS partition (<tt class="filename">hda5</tt> in our previous example). </p> <div class="note"> <div class="admonhead"> <img alt="[Note]" src="../images/note.png" /> <h3 class="admontitle"> Note </h3> </div> <div class="admonbody"> <p> Some host distributions use custom features in their filesystem creation tools (E2fsprogs). This can cause problems when booting into your new LFS, as those features will not be supported by the LFS-installed E2fsprogs; you will get an error similar to <tt class="computeroutput">unsupported filesystem features, upgrade your e2fsprogs</tt>. To check if your host system uses custom enhancements, run the following command: </p> <pre class="userinput"><kbd class="command">debugfs -R feature /dev/<em class="replaceable"><tt>[xxx]</tt></em></kbd></pre> <p> If the output contains features other than: dir_index; filetype; large_file; resize_inode or sparse_super 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: </p> <pre class="userinput"><kbd class="command">cd /tmptar xjf /path/to/sources/e2fsprogs-1.38.tar.bz2cd e2fsprogs-1.38mkdir buildcd build../configuremake #note that we intentionally don't 'make install' here!./misc/mke2fs /dev/<em class="replaceable"><tt>[xxx]</tt></em>cd /tmprm -rf e2fsprogs-1.38</kbd></pre> </div> </div> <p> If a swap partition was created, it will need to be initialized for use by issuing the command below. If you are using an existing swap partition, there is no need to format it. </p> <pre class="userinput"><kbd class="command">mkswap /dev/<em class="replaceable"><tt>[yyy]</tt></em></kbd></pre> <p> Replace <em class="replaceable"><tt>[yyy]</tt></em> with the name of the swap partition. </p> </div> <div class="navfooter"> <ul> <li class="prev"> <a accesskey="p" href="creatingpartition.html" title= "Creating a New Partition">Prev</a> <p> Creating a New Partition </p> </li> <li class="next"> <a accesskey="n" href="mounting.html" title= "Mounting the New Partition">Next</a> <p> Mounting the New Partition </p> </li> <li class="up"> <a accesskey="u" href="chapter.html" title= "Chapter 2.
