Hi Mark, Thank you so much for explaining the CSV at great length. I was hoping to understand, if there are any changes in the below cluster processes and sub-interactions among the nodes. The reason why ask I is, no one mentions it and I spoke to multiple PFE who happen to be friends/acquaintances who tell me that if there is not documentation on the new docs / techcommunity.microsoft.com/ means there have not been much changes. Plus I had luckily read "How a Server Cluster Works", so just asking: Nodes Forming a cluster. Nodes Joining a cluster. Nodes Leaving a cluster. Heartbeats mechanism in the Node for keep alive. Regroup events in nodes in case of failures. Quorum Arbitration in a cluster. Disk Arbitration in a cluster. Monitoring the health of resources (polling). Bringing a resource group online. Taking a resource group offline. Failing a resource group over. Failing a resource group back.
