I'd like to know how it's possible using the lvm cli tool to clone an existing lvm thin volume, creating another thin-volume with the same contents (but possibly a larger size) as the original one.

So something like LXC does when you execute lxc-clone.

The only information I could find about creating a thin volume with another as its origin was about creating snapshots.

Apparently, this is done by simply creating a new volume and then copying over the data from the original one with:

dd if=/dev/mapper/original_thin_volume of=/dev/mapper/new_thin_volume conv=sparse

Best way:

virt-sparsify indisk outdisk
