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.

Hello list,
i've got a (hopefully not) serious problem with my lvm installation.
I did some changes in my XEN-networking and wanted to reboot my
server.
For this I did shutdown every DOM-U and tried to stop lvm with
'vgchange
-a n'. At this point lvm states 'Incorrect metadata area header
checksum', before this every worked fine. I tried to start lvm
immediately without success, a reboot didn't help either.
I searched the net (almost two days now) for a solution, without
success.
1) It's not a filter-issue (lvm.conf), only loop-devices are scanned.
2) vgcfgrestore doesn't work either (tried only testrun)
3) pvcreate --uuid xxx --restorefile /etc/lvm/archive/xxx_00039.vg xxx
says, the uuid is already in use on /dev/loopX (correct device). I
didn't try the '--force'-option, I'm a coward at last :(
The last change (and reboot) was in november. I added two new drives
and
growed the raid, rebooted the server and growed one lv. All without
any
error. There's only one PV.
If you need any information (configs etc), I'll post everything ;)

$>pvscan
Incorrect metadata area header checksum
Incorrect metadata area header checksum
WARNING: Volume Group alice is not consistent

Any help is appreciated!
