Good luck.FTA, thanks for your tips. and I really wonder whether these errors "Incorrect metadata area header checksum,Volume group VolGroup00 metadata is inconsistent" is impossible to recover.Or what I need to deal, is to follow: http://thread.gmane.org/gmane.linux.redhat.fedora.general/196481 to recover all lvm's data?

FWIW, I did recover data from an LVM that was removed (on purpose) in part of an upgrade. I couldn't mount the drive as the LVM recovery procedures listed and I thought I was toast. If I left the drive in the computer, the computer would try to add the drive back into the LVM no matter what I tried.
To complicate things even further, the drive was part of a RAID 1 array. I put the drive into a carrier. As the drive was SATA, I ended up getting a Thermaltake carrier that supports SATA and IDE (end product plug). :)
It was many months ago but I used normal recovery tools to pull the data off of the drive. I would have to look at my notes which are at home. If I remember I will see if I can find my notes.
Basically, it is possible but I don't know if it is harder as this was my first time.
