Hmmm.., shouldn't be the case.
Could you send me all the metadata of your VG "server" attached in private email
(mge at sistina.com) for further investigation?
You can create the copies running this script:
#!/bin/sh
for d in $(pvscan|sed '/server1/!d;s!^.* PV "!!;s!" .*$!!'); do
dd if=$d of=$(basename $d).VGDA bs=1k count=512
done
Thanks,
