<div>thanks for you quick response.</div>

<div>Now there's something going on after creating an image. It fails with an error. I'll investigate this and get back to you soon with results :)</div>

<div>Hi Yves,<br>
<br>
in the image template (im.conf) do PATH = /var/lib/one/Master.raw,<br>
instead of SOURCE = /var/lib/one/Master.raw<br>
<br>
The rest looks fine.<br>
<br>
cheers,<br>
