What is not clear to me is how to combine lvm-vdo with lvmthin (for fast CoW snapshots) and/or lvmcache (for SSD caching of an HDD pool). For example, with the old /dev/mapper/vdo style volumes (ie: the one created via vdo create) one can do something as physical_dev -> vdo -> lvmthin -> lvmcache. How to do the same with lvm-vdo?
