* Have a (virtual) machine with 2 disk drives
* Install openSUSE choosing "Guided Setup" ��� LVM ��� non-BtrFS for root on
"partitioning" stage leaving everything else default
* boot to installed system
* run following commands as root (basically following lvmcache(7) man page)

# pvcreate /dev/sdb
# vgextend system /dev/sdb
# lvcreate --type cache-pool -l 100%FREE -n lvc_root system /dev/sdb
# lvconvert --type cache --cachepool system/lvc_root system/root
(type yes)

then run `lvs` or `lvdisplay` command to trigger the issue
