I have a homeserver running under XenServer control with 3x1TB discs inside, one for XenServer and two mirrored(using Intel's fakeRAID and dmraid) for VMs and a user data(but now I think RAID didn't work). I tried to pass PCI card to VM using PCI-passthroug and I read somewhere that I need to recompile kernel with pciback module but something went wrong(I made mistake in /boot/extlinux.conf and server couldn't run) and I had to use LiveCD of GPartEd(I already had it on USB key) to correct this. But when I re-run the server all VDIs were gone. I have completly no idea what could go wrong.

I tried to repair RAID using dmraid -R in the hope that everything will return to noramal but now I think this done more bad than good(and corrupted rest of LVM table...).

Is there any possibility to recover this SR or only data from one(~100GB) of VDI?

I also wants to apologise for my English, I'm not from English-speaking country and I'm only 16 years old, so I hadn't "time" to learn it(school isn't good place to do this) in sufficient way.
