i'm quite new to Proxmox and have a very basic question.
imagine a "typical" scenario in a small company with maybe 5 to 10 VMs with a quite low average load.
not negotiable is to have two hosts (e.g. to have primary/secondary DC or NIS master and slave or...) on separate physical machines for redundancy.
the idea is to create a cluster, for easy movement of the VMs and so on.
i just did such a test setup (with V6.2) and after the first verve the big disapointment came up when i switched off one of the two machines!
the other one is not useable anymore, i can't even open a root shell to fix/adjust anything, wtf?!?
so instead of adding any kind of redundancy i achieved exactly the oposite: in case of one of two machines failing not 50% of the VMs are down but all 100%.
even if i would take 3 machines for a cluster (assuming 2 are still working in case a third one fails) it would be too risky for me.
i can setup the two machines as independend nodes but loose some highly appreciated features like transfering a live VM from one host to another, for example for "manual load balancing" in case it is useful.
am i missing anything or is this "typical" scenario not possible with Proxmox in cluster mode and with two completely independ machines only where i have to move machines via backup and restore?!?
