AFAIK just "adding a network" should not do anything<br>in itself.

Would that be the right way to do this ?<br><br>I'd say the right way is probably to plan beforehand and create your<br>storage network ahead. Choose nics for that, connect them to a separate vlan,<br>give them IP addresses, give these addresses names (different from the names<br>given to addresses of other nics), and use these names when configuring<br>the gluster storage.<br><br>> If that’s the case how could I<br>> move the engine bricks over to that network to get it off my ovirtmgmt<br>> bridge ? Or is there may be more prefered way to complete the HC-Setup ?<br><br>If you provided IP addresses of the wrong nics and now want to change that,<br>then I have no idea - no personal experience with gluster.
