108    
109     <p>In the past restoring to a different location was not supported by <b>Clonezilla Live</b> at all. Because of that, a script called <b>reloc-img</b> was added to <b>Clonezilla-SysRescCD</b>, which would help the user perform this task.</p>
110    
111     <p>Recent versions of <b>Clonezilla Live</b> partly support restoring to a different location, so the <b>reloc-img</b> script is obsolete, and has been removed. <b>Clonezilla Live</b> now supports:</p>
112    
113     <ul>
114     <li>Relocation of a disk image (restoring a whole disk)</li>
115     <li>Relocation of a partition image (restoring a partition)</li>
116     </ul>
117    
118     <p><b>Clonezilla Live</b> does not support:</p>
119     <ul>
120     <li>Relocation of a single partition contained into a disk image.<br>
121     <br>
122     Imagine you have a disk backup image named <b>hda-2009-02-02</b>. The image contains three partitions, <span style="color: Red; font-weight: bold;">hda1</span> (operating system), <span style="color: Red; font-weight: bold;">hda2</span> (user data) and <span style="color: Red; font-weight: bold;">hda3</span> (other data).<br>
123     <br>
124     You want to restore your <b>other data</b> partition (<span style="color: Red; font-weight: bold;">hda3</span>), to a different system (partition <span style="color: Green; font-weight: bold;">sdb2</span>) but there is no way to restore (extract) a single partition from a disk image - you can only restore the whole disk.
125     </li>
126     </ul>
127    
128     <p>In order to address this situation, two new scripts have been written for <b>Clonezilla-SysRescCD</b>: <b>imginfo</b> and <b>imgconvert</b>
129

152     <p>The script will be used to convert an existing <b>disk</b> image file to a new <b>partition</b> image file.</p>
153    
154     <p><b>imgconvert</b> can create two type of images:</p>
155    
156     <ol>
157     <li><b>Temporary image</b><br>
158     This type of image is created by linking the data files of the existing disk image to the new partition image. This means that the original image <b>must</b> be present for the new image to be used. This is the default image type created by <b>imgconvert</b>.
159     </li>
160     <li><b>Permanent image</b><br>
161     This type of image is created by copying the data files from the existing disk image to the new partition image. This means that the original image is not needed in order to use the new one. Permenant image files are created using the command line parameter <b>-p</b>.</li>

341    
342     <p>A Linux system that has been restored to a new disk/partition, is usually not ready to be booted right after the restoration procedure is finished.</p>
343    
344     <p>There are two more steps that you may have to take:</p>
345    
346     <ul>
347     <li>Fix <b>/etc/fstab</b></li>
348     <li>Reinstall <b>GRUB</b>.<br>
349     I will assume GRUB is your boot manager, as it is the usual case nowadays.</li>
350     </ul>
351    
352     <p>For this example I will assume that you have restored a Linux system (that used to be in <font color="Red"><b>sdb</b></font>), to a new disk (<font color="Green"><b>hda</b></font>), and that it contains three partitions, <b>/</b> (the root partition), <b>/home</b> (user's partition) and a <b>swap</b> partition. You must be really careful here, as the name of the new disk depends on the system to be booted. If it uses one of the newest Linux kernels (using the libata disk driver), ALL your disks will be recognised as SCSI. More info: "<a href="annex-a-devices.html#annex-a-scsi-ata">Identifying devices in Linux</a>" section "<a href="annex-a-devices.html#annex-a-scsi-ata">SCSI disks when there are none!!!</a>".</p>
353    
354     <p>This is what we have:</p>
355    
356     <p class="newcode">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;root partition&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;home partition&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;swap partition<br>
357     Old system&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<font color="Red">/dev/sdb1</font>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<font color="Red">/dev/sdb2</font>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<font color="Red">/dev/sdb3</font><br>
358     New system&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<font color="Green">/dev/hda1</font>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<font color="Green">/dev/hda2</font>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<font color="Green">/dev/hda3</font></p>
359    
360    
361     <H3><a name="reloc-img-boot-fstab"></a>Fixing /etc/fstab <span class="hideprint">[<a href="#reloc-img-top" title="go to top of the page">^</a>]</span></H3>
362    
363     <p>Since we are still in <b>Clonezilla Live</b>, right after the restore procedure has finished, we will use it to mount our restored root partition, and edit its <b>/etc/fstab</b>. We issue the commands:</p>
364    
365     <p class="newcode">mkdir /new-root<br>
366     mount /dev/hda1 /new-root<br>
367     vi /new-root/etc/fstab</p>
368    
369     <p>The contents of <b>/etc/fstab</b> could be something like</p>
370    
371     <p class="newcode"><font color="Red">/dev/sdb1</font>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;/&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;reiserfs&nbsp;&nbsp;&nbsp;acl,user_xattr&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1&nbsp;1<br>
372     <font color="Red">/dev/sdb2</font>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;/home&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;reiserfs&nbsp;&nbsp;&nbsp;defaults&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1&nbsp;2<br>
373     <font color="Red">/dev/sdb3</font>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;swap&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;swap&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;defaults&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;0&nbsp;0</p>
374    
375     <p>and we have to change ti to</p>
376    
377     <p class="newcode"><font color="Green">/dev/hda1</font>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;/&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;reiserfs&nbsp;&nbsp;&nbsp;acl,user_xattr&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1&nbsp;1<br>
378     <font color="Green">/dev/hda2</font>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;/home&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;reiserfs&nbsp;&nbsp;&nbsp;defaults&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1&nbsp;2<br>
379     <font color="Green">/dev/hda3</font>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;swap&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;swap&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;defaults&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;0&nbsp;0</p>
380    
381     <p>Finally, we unmount the partition, and we are ready to reboot</p>
382    
383     <p class="newcode">umount /new-root<br>
384     reboot</p>
385

387    
388     <p>When <b>Clonezilla-SysRescCD</b> menu appears, we select <i><b>Tools &gt; Super Grub Disk</b></i></p>
389    
390     <p>Then we select <i><b>Super Grub Disk &gt; Super Grub Disk (WITH HELP) &gt; English Super Grub Disk &gt; Gnu/Linux &gt; Fix Boot of Gnu/Linux (GRUB)</b></i>. From this entry we will be able to reinstall GRUB to our hard disk.</p>
