<h3>Resizing filesystems</h3>
</center>
You may want to resize a UML filesystems because it isn't large
enough. This is a common complaint with the filesystems available for
download here since they tend to be just big enough to hold what's
pre-installed in them, making it tough to install more stuff.
<p>
<ul>
<li>
Shut down the uml guest
<blockquote>
<tt>
<font color="#000000" where="UML">UML# halt</font>
</tt>
</blockquote>
</li>
<li>
Make a backup of the file you want to resize.
</li>
<li>
If you have any COW files which have the file you want to resize as a
backing file then make a backup of the cow files, too.
</li>
<li>
If you want to merge the cow file with uml_moo, do it now. Otherwise
remove the cow file to avoid confusion.
</li>
<li>
Make sure the filesystem is in a clean state.
<blockquote>
<tt>
<font color="#000000" where="host">host% e2fsck -f <i>filename</i>
</font>
</tt>
</blockquote>
</li>
<li>
Resize the file.
<tt>
<pre>
<font size="-1">
<font color="#000000" where="host">host%
dd if=/dev/zero of=<i>filename</i> bs=1 count=1 seek=<i>newsize</i> conv=notrunc
</font>
0+0 Records in
0+0 Records out
</font>
</pre>
</tt>
<i>newsize</i> can be any size recognized by "dd", such as "256M",
"4G", or "2T". The length of the file should have changed, but not
the actual filesize as with "ls -ls".
</li>
<li>
Resize the filesystem.
<blockquote>
<tt>
<font color="#000000" where="host">host% resize2fs -p <i>filename</i>
</font>
</tt>
</blockquote>
</li>
<li>
If you don't trust your luck and/or your computer run:
<blockquote>
<tt>
<font color="#000000" where="host">host% e2fsck -f <i>filename</i>
</font>
</tt>
</blockquote>
</li>
<li>
Start the uml with the new filesystem
</li>
</ul>
