Based on recent forum postings/conversations it seems that the best strategy I've been able to come up for a multinode setup is:
- have a cheap $10 a month vps just the Master Node for the cluster(amazon/togglebox). This is the one machine that must never change or go down, etc.
I came to this conclusion based on the fact that Proxmox is clustering is based on having a master node. And, once you remove a node from a cluster they must never see each other again.
This would allow you to add/remove nodes freely without worrying about which one you want to upgrade or down-grade as it will never be the master node as that one will never change and be static.
- have multiple dedicated servers (rented or your own in colo). This way you can add/change/remove nodes at will just migrating your vms to the new servers as you bring them online and remove the old nodes as you go. Since your master node is static, you should never have to worry about upgrading or downgrading it.
