<div class="WordSection1">
<p class="MsoNormal">We have created 200+ resources on our new a 5-node Linstor cluster. The database servers each have 4 NICs in 2 bonded sets. There’s a bond on the “front” (client-facing) side of the server and a bond on the “back” (replication network)
side of the server. When I built the cluster, I didn’t know about NIC management. I wanted the servers to use their “back” bonds for DRBD traffic, so I created separate DNS names for the back bonds. For example, if a server is named “server-a,” then the DNS
name “server-a” resolves to the IP address of the front bond, and “server-a-repl” resolves to the IP address of the back bond.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">When I created the cluster, I used node names server-a-repl, server-b-repl, server-c-repl, server-d-repl, because I thought that was the way to make sure DRBD used the back bonds. That was dumb. I should have left the node names alone and
just created additional NICs and Linstor could have used PrefNic to assign the proper replication links.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">So here’s the question. Is there an easy, non-disruptive way to re-name cluster nodes and re-assign replication links without rebuilding almost everything from scratch?<o:p></o:p></p>
