<p class="MsoNormal">Hi,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I had a number of Windows VMs running in oVirt 3.3 that required their preallocated OS disks to be extended. Each OS disk had a single partition taking up the entire drive. As per
<a href="http://www.ovirt.org/Features/Online_Virtual_Drive_Resize">http://www.ovirt.org/Features/Online_Virtual_Drive_Resize</a> I shut down all the VMs, extended each OS disk by 10GB (total 25GB) via the web interface, then clicked OK. The tasks appeared
to complete successfully and each of the OS disks had the expected real size on the Gluster storage volume.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">On startup however none of the VMs would recognize their OS disk as being a bootable device. Checking one of the OS disks via TestDisk (both quick and deep scans) revealed no partitions and the error ‘Partition sector doesn’t have the endmark
0xAA55’. It appears that each OS disk was wiped as part of the extension process although I’m really hoping that this isn’t the case!<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Are there any other approaches I could use to attempt to recover the OS disk data or at least verify whether the original disk partitions are recoverable?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Thanks,<o:p></o:p></p>
