send / receive process can be triggered with the following command;
$ thin_send ssd_vg/CentOS7.6 ssd_vg/li0 | ssh root@target-machine thin_recv kubuntu-vg/li0
or you can use socat for streaming;
target-machine$ socat TCP-LISTEN:4321 STDOUT | zstd -d | thin_recv kubuntu-vg/li0
source-machine$ thin_send ssd_vg/CentOS7.6 ssd_vg/li0 | zstd | socat STDIN TCP:10.43.8.39:4321
