We recently configured a 2 node server 2012 Hyper V cluster attached to a Tegile SAN via ISCSI using CSV volumes. I can find little to no documentation as to deployment of server 2012 HV clusters. My questions are:
1. Does server 2012 hyper V require a physical domain controller in order to start the cluster in the event that all virtual domain controllers go offline?
2. What is the recommended configuration for the disk witness in quorum? Should it have a drive letter assigned? Should it be made a CSV volume? I recently live migrated all of my VMs to host 1 in order that I could update and restart host 2. When I restarted host two, all VM’s went down and I received the following error: “The Cluster service is shutting down because quorum was lost. This could be due to the loss of network connectivity between some or all nodes in the cluster, or a failover of the witness disk.”
I suspect that host 2 was the current “Owner” of the cluster disk 1 (Disk witness) and it didn’t automatically switch owners. Do I need to manually "move available storage" to the other host prior to reboot?
Any ideas? I cant have the entire cluster crashing whenever we need to update hosts.
