[QUESTION] How do you add a new node to Longhorn?

Question

Environment:

• Longhorn version: 1.1.1
• Kubernetes version: 1.20.6
• Node config
  • OS type and version: CentOS7
  • CPU per node: 8
  • Memory per node: 64
• Underlying Infrastructure (e.g. on AWS/GCE, EKS/GKE, VMWare/KVM, Baremetal): oVirt

I apologize as I wasn't able to find this information somewhere else. I have Longhorn 1.1.1 working just fine but we had to add a fourth node and it's not recognized by Longhorn. Is there an auto-discovery and if not how do I get this latest node and nodes afterward added into Longhorn?

Longhorn was installed via helm.

This was my mistake, I had forgotten:

yum install iscsi-initiator-utils
