Hello guys,<div><br></div><div>I have been facing a problem with a server who can't sync at all due to network issues. The NIC (two Intel e1000e) is showing several errors and is being dropped off. Sometimes at the primary node, sometimes at the secondary. It will not sync.</div>
<div><br></div><div>I have an unused NIC on both servers, and I would like to use them instead. What should I do to move the configuration from one set of IP's to another??</div><div><br></div><div>So, that is my current <font class="Apple-style-span" face="'courier new', monospace">/etc/drbd.conf</font>:</div>

</div><div><br></div><div>Is it enough to just change the <font class="Apple-style-span" face="'courier new', monospace">/etc/drbd.conf</font> on both servers? What is the exact procedure? I'm using DRBD v8.2.6.</div>
<div><br></div><div>Thanks,</div><div>Marcelo</div>
