Hi Jamie,<br>
<br>
thanks for you answer.<br>
<br>
I did the steps you suggested and fail with an error - it seems that there's something messed up when deploying a vm.<br>
The error occures on cloning.<br>
<br>
Error executing image transfer script: Error cloning /dev//dev/vg01/master//dev/vg01/master to /dev//dev/vg01/master//dev/vg01/master-429-0<br>
<br>
I intended to clone /dev/vg01/master to /dev/vg01/master-429-0<br>
<br>
<br>
I'll have a look at the drivers - but maybe I'm doing something wrong?<br>
<br>
Thanks,<br>
