<question id="ccd-disklabel">
<para>Why can I not edit the disklabel on my ccd?</para>
<para>Why can I not edit the disklabel on my &man.ccd.4;?</para>
</question>
<answer>
<para>The symptom of this is:</para>
<screen>&prompt.root; <userinput>disklabel ccd0</userinput>
<screen>&prompt.root; <userinput>disklabel <replaceable>ccd0</replaceable></userinput>
(it prints something sensible here, so let us try to edit it)
&prompt.root; <userinput>disklabel -e ccd0</userinput>
&prompt.root; <userinput>disklabel -e <replaceable>ccd0</replaceable></userinput>
(edit, save, quit)
disklabel: ioctl DIOCWDINFO: No disk label on disk;
use "disklabel -r" to install initial label</screen>
<para>This is because the disklabel returned by ccd is actually
<para>This is because the disklabel returned by &man.ccd.4; is actually
a <quote>fake</quote> one that is not really on the disk.
You can solve this problem by writing it back explicitly,
as in:</para>
<screen>&prompt.root; <userinput>disklabel ccd0 &gt; /tmp/disklabel.tmp</userinput>
&prompt.root; <userinput>disklabel -Rr ccd0 /tmp/disklabel.tmp</userinput>
&prompt.root; <userinput>disklabel -e ccd0</userinput>
<screen>&prompt.root; <userinput>disklabel <replaceable>ccd0</replaceable> &gt; <replaceable>/tmp/disklabel.tmp</replaceable></userinput>
&prompt.root; <userinput>disklabel -Rr <replaceable>ccd0</replaceable> <replaceable>/tmp/disklabel.tmp</replaceable></userinput>
&prompt.root; <userinput>disklabel -e <replaceable>ccd0</replaceable></userinput>
(this will work now)</screen>
