If you create a proxmox cluster of nodes that have a VM, will it be easy to work with?

Question

Proxmox

Good afternoon!
There are 2 proxmox nodes, I want to unite them into a cluster. How will the guests behave? Will they get hurt? Will there be a break in the work of the guests?

Answer 1

if you need shared storage, then it will have to be done by drbd or something like that, then you can’t do without downtime.
and if it just drives virtual machines from one console, then it seems there will be no downtime

Answer 2

If there are already running machines there, you will not be able to connect two nodes. He will swear and say delete all machines from the node. So if you need to connect two nodes into a cluster, you need to do this immediately after installation, and then transfer the machines there!
