just note - please never use version 1 metadata format for new LVM2 config,
you will avoid problems in future, limits is one of them:-)

The only situation where this is really needed is compatibility
with lvm1 (2.4 kernel - RHEL3 for example).
(and after upgrade you can always use vgconvert to upgrade to LVM2 text
metadata format)
