I suspect that a quorum<br>disk is not necessary, though if you have a SAN anyway, I wouldn't argue<br>against using it. Unless you need the heuristics though, it's probably<br>not needed. You
can safely build a 2-node cluster, you just need to make<br>sure your fence devices work (which is needed, regardless).<br><br>I have a tutorial that shows how to implement a cluster using cman,<br>clvmd and other components. It also discusses the cluster components<br>from a high-level, which may help.<br><br><a href="https://alteeve.com/w/2-Node_Red_Hat_KVM_Cluster_Tutorial" target="_blank">https://alteeve.com/w/2-Node_Red_Hat_KVM_Cluster_Tutorial</a><br><br>-- <br>Digimer<br>Papers and Projects: <a href="https://alteeve.com" target="_blank">https://alteeve.com</a><br><br><br> </div> </div> </div></body></html>
