## Motivation 

 Thin Provisioning is an imporant feature and 
 as such it makes sense to have at least a basic test - meaning 
 deployment of the system, which will implicitly test the subsystem itself. 
 Yast team has fixed a bug in Yast in February about Thin Provisioned LVM 
 installation. It showed up that there is no test coverage for this in 
 OpenQA. 

 ## Acceptance criteria 
 * **AC1:** An openQA test scenario conducting installation on thin-LVM exists and is scheduled on SLE15, openSUSE Tumbleweed and openSUSE Leap 15.0 
 * **AC2:** Also on SLE12SP4 unless there is a clear message that thin-LVM is not supported on SLE12, see [bsc#1027586](https://bugzilla.suse.com/show_bug.cgi?id=1027586) 

 ## Tasks 
 * Understand thin provisioning, e.g. watch https://youtu.be/E4H6Ar7XIjU or read https://www.theurbanpenguin.com/thin-provisioning-lvm2/ 
 * Test thin-LVM installation manually on TW or SLE15 
 * Resurrect https://github.com/os-autoinst/os-autoinst-distri-opensuse/pull/2489 and adapt for storage-ng 
 * Get involved in https://bugzilla.suse.com/show_bug.cgi?id=1027586 to find out how tho handle the pre-storage-ng situation 
 * optionally keep it working for pre-storage-ng as necessary for SLE12SP4 
 * Add corresponding tests for all AC1 mentioned versions, distris
