<br>
cockpit is enabled by default when you use ovirt-node. You will<br>
probably have to install the necessary cockpit packages yourself on<br>
pure CentOS - you will need cockpit and ovirt + gdeploy cockpit<br>
plugins (sadly I do not recall the exact package names).<br>
<br>
With regards to arbiter and the wizard.. I really do not know, but I<br>
will alert my colleagues who might have more detailed knowledge of the<br>
gluster part.<br>
<br>
Denis, Sahina: can you please help me here?<br>
<br>
Best regards<br>
