[linux-lvm] "System ID" entry missing in metadata (LVM2) ?!

thanks for your response Jonathan, but I want to share the VGs between 
the hosts. So I hoped that there is something like this functionality:
-> "vgimport VG" writes some kind of hostid (system_id?) in the metadata
-> other hosts can´t access the VG
-> "vgdeport VG" removes the ID, so anyone else can import the VG

My C knowledge isn´t very good, but the sources seem to include a 
functionality like the one mentioned above.

Kind regards,
