<p class="MsoNormal"><span style="font-size:8.0pt;font-family:"Arial","sans-serif"">Hello – first post here – I was referred to this group from xen-users.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:8.0pt;font-family:"Arial","sans-serif""><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:8.0pt;font-family:"Arial","sans-serif"">I started on xen-users, and then went to the testdisk forum. My issue is one of my own causing but has lead to the discovery of a problem I’m trying to understand / resolve
in interpreting lvm structure...<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:8.0pt;font-family:"Arial","sans-serif""><o:p> </o:p></span></p>

<p class="MsoNormal"><span style="font-size:8.0pt;font-family:"Arial","sans-serif""><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:8.0pt;font-family:"Arial","sans-serif"">In short, I allowed xen to reinitialize an HBA storage repository. I lost an important VM / some data which I thought was backed up.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:8.0pt;font-family:"Arial","sans-serif""><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:8.0pt;font-family:"Arial","sans-serif"">I have used photorec to recover VHD files, and some of them work / can be read by remounting them in xen or by using a tool like winimage.
<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:8.0pt;font-family:"Arial","sans-serif""><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:8.0pt;font-family:"Arial","sans-serif"">But some of them are damaged. I want to hopefully recover a few files from these LVMs<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:8.0pt;font-family:"Arial","sans-serif""><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:8.0pt;font-family:"Arial","sans-serif"">In some cases I suspect the LVM may be fragmented and testdisk may have recovered separate lvm files when there was really supposed to be a single file.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:8.0pt;font-family:"Arial","sans-serif""><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:8.0pt;font-family:"Arial","sans-serif"">I’m wondering if there is any way to stitch them back together. Testdisk is normally able to pull partition table data and then navigate through a damaged hard drive / partition
/ disk image to allow recovery of files and folders.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:8.0pt;font-family:"Arial","sans-serif""><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:8.0pt;font-family:"Arial","sans-serif"">In the case of my VHD files however it doesn’t work. I expect it’s got something to do with the way the VHD stores information like the partition table etc. Testdisk doesn’t
see a normal partition table / is unable to recognize the partition and when I try to force it too my options for recovery are limited.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:8.0pt;font-family:"Arial","sans-serif""><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:8.0pt;font-family:"Arial","sans-serif"">I’ve been seeking help from the testdisk forum – but can anyone confirm that lvm2 is what xen is using?<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:8.0pt;font-family:"Arial","sans-serif""><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:8.0pt;font-family:"Arial","sans-serif"">Are there any other recovery tools I should be aware of for this scenario particularly anything on recovering from damaged vhd’s or relinking parts of vhd’s to their parents,
etc.?<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:8.0pt;font-family:"Arial","sans-serif""><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:8.0pt;font-family:"Arial","sans-serif"">Any documentation / pointers would be appreciated! If there is an alternative to using testdisk / treating this like a “hardware failure” and more like a logical reconstruction
that would be great, however my attempt at googling / readking lvm2 command man pages didn’t show me anything obvious…<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:8.0pt;font-family:"Arial","sans-serif""><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:8.0pt;font-family:"Arial","sans-serif"">Thank you in advance!!<o:p></o:p></span></p>
