</span>It works on ovirt 3.5 and master and it should work also in all previous versions.<br>
<br>
Please open a bug for this:<br>
1. Describe the configuration you are modifying<br>
2. Describe the steps you take<br>
3. Include engine log<br>
4. Include vdsm log from the host trying to add new devices<br>
