<div>
<div>I am trying to setup a cluster of two nodes, with self hoste Engine.</div>
<div>Things went fine for the first machine, but it as rather messy about the second one.</div>
<div>I would like to have load balancing and failover for both management network and storage (NFS repository).</div>
<div> </div>
<div>So what should I exactly do to get a working network stack which can be recognized when I try to add this host to the cluster ?</div>
<div> </div>
<div>Have tried configuring bonds and briges using Cockpit, using manual "ifcfg" files, but all the time I see the bridges and the bonds not linked in the Engine interface, so the new host cannot be enrolled.</div>
<div>If I try to link "ovirtmgmt" to the the associated bond, I have a connectivity loss because it is the management device, and I have te restart the network services. As management configuration is not OK, I can't setup the storage connection.</div>
<div> </div>
<div>And if I just try to activate the host, I will install and configure things and then complain about missing "ovirtmgmt" and "nfs" networks, which both exist and work and Centos level.</div>
<div> </div>
<div>The interface, bonds and bridge names are copy/paste from the first server.</div>
<div> </div>
<div># brctl show ovirtmgmt<br>bridge name bridge id STP enabled interfaces<br>ovirtmgmt 8000.44a842394200 no bond0</div>
<div># ip addr show bond0<br>33: bond0: <BROADCAST,MULTICAST,MASTER,<wbr>UP,LOWER_UP> mtu 1500 qdisc noqueue master ovirtmgmt state UP qlen 1000<br> link/ether 44:a8:42:39:42:00 brd ff:ff:ff:ff:ff:ff<br> inet6 fe80::46a8:42ff:fe39:4200/64 scope link <br> valid_lft forever preferred_lft forever<br># ip addr show em1<br>2: em1: <BROADCAST,MULTICAST,SLAVE,UP,<wbr>LOWER_UP> mtu 1500 qdisc mq master bond0 state UP qlen 1000<br> link/ether 44:a8:42:39:42:00 brd ff:ff:ff:ff:ff:ff<br># ip addr show em3<br>4: em3: <BROADCAST,MULTICAST,SLAVE,UP,<wbr>LOWER_UP> mtu 1500 qdisc mq master bond0 state UP qlen 1000<br> link/ether 44:a8:42:39:42:00 brd ff:ff:ff:ff:ff:ff</div>
<div> </div>
<div>By the way, is it mandatory to stop and disable NetworkManager or not ?</div>
<div> </div>
<div>Thanks for any kind of help :-)</div>
