Proxmox HA without autobot

[mcmyst]

Hi,

I am looking for a way to enable HA without auto boot for VM.

In fact, I want to be sure that we (easiest way possible) decide to start the VM (manually) in case of failure on main server. In that way we would never be in a situation of split brain.

Do you know a way to do that ?

Thank you

If you have to start the VM manually, you'll never get HA.
Just put the VM on a storage shared between hosts and don't enable any HA on the VM itself. Just start it manually on one host.

The way you are talking about doesn't allow to start VM on second host. Because the VM config files will stay on primary host that is down. The only way to have VM on secondary host are:
- copy VMID to secondary host : not a clean way
- restore backup : too long
- another way : HA without autoboot

I think you are right.
What if you set 'disable' to the VM HA resource ?

Never tested... It the reason why I am asking .
