<div>Hi,<br></div><div><br></div><div>I am reading the user's guide for DRBD and there is something I want to clarify.</div><div><br></div><div>In Chapter 8 ("Integrating DRBD with Pacemaker clusters"), section 8.1.4 "OpenAis communication channels", it is said that "the absolute minimum requirement for stable cluster operation is two independent communication channels in a redundant ring"</div>
<div><br></div><div>Does it mean that if I have a cluster composed of two nodes, I need two NIC on each node? (one for DRBD replication as well as Pacemaker and the other one only for Pacemaker)?</div><div><br></div><div>
Thank you.</div><div><br></div><div>Romain Chanu</div><div><br></div><div><br></div><div><br></div>
