[CentOS] HowTo copy a Logical Volume to another LV

hello all,

Hoping for some help on copying Logical Volumes.

I would like to copy an existing LV to a newly formed LV.

I don't want to do a snapshot of an existing LV.

Only way I've seen is to mount the to LV and:
mount /dev/vg00/lv00 /mnt/orig
mount /dev/vg00/lv01 /mnt/copy

cd /mnt/orig
tar cf - ./ |(cd /mnt/copy; tar xf - )

Is there a LV tool to do this?
Or an option used with lvcreate, such as --autobackup?
Or maybe pvmove, but that seems more for moving To LV from PV or vesa versa?

Thanks in advance,

Jesse Waters
