I googled many times but couldn't find an answer. What I want is cloning an LVM thin provisioning volume to another thin volume.
For now I know
dd can clone a thin volume as following:
dd if=/dev/mapper/vg_thin01 of=/dev/mapper/vg_thin02 bs=1M
But the new cloned volume will be full size! How can I make it to sparse/thin volume?
(Actually the thin volume will be used for DomU storage in Xen or KVM )
