Hello all,
I'm looking at really tight rack, power, and network requirements for an upcoming PVE4.2 deploy. I got the idea that I could deploy a 3 node cluster (with shared storage) with 1 of the nodes only acting to vote in the quorum for HA. The idea being that I don't currently have enough room for a 3rd real node until a date months from now, but have to deploy the system now.
My idea is to use an Intel NUC as the 3rd node, but obviously I don't want any VMs to actually run from there. I'm just looking to satisfy PVE's 3-node requirement, which is a good requirement to have, I understand why it's there, I just need to work around it for now and accept the risk that comes with it.
So is this a design that will work? How can I set that node to not allow VM's to run from it, but still participate in the cluster? I realize the NUC has single power supply, single network jack, etc. However, the alternative is not enabling HA on the VM's, which I would very much like to do. If there is a better way to go about running this system now, I'm all ears.
Thoughts? Criticisms?
