[linux-lvm] Please help, [Incorrect metadata area header checksum]

[Jonathan Brassow]

Could you do a 'pvscan -vvvv' and post (attach) the output?

You could also copy the first several MB of the PVs that compose  
"alice".  We could then either look directly at them, or you could  
feel free to be more brave with #2 and #3 below - given that you will  
have a backup of the front of each disk.
