I'm not an expert of this area and not sure if you can rescue it or not,
but the following document might be helpful to you.

Chapter 6. LVM Troubleshooting
http://www.redhat.com/docs/en-US/Red_Hat_Enterprise_Linux/5.5/html/Logical_Volume_Manager_Administration/troubleshooting.html

6.4. Recovering Physical Volume Metadata

Thanks,
