So I have a proxmox server configured in Software Raid that comes from Hetzner. Like when you pull the image you can figure a software RAID 1. Now the big issue how do I know if a disk stopped working and if I add 2 more SSDs do I need to configure anything or It won't boot at all ?

In this case you will see a degraded mdraid, and you will ask the guy from Hetzner for a replacement. Then you will need to add the new HDD/SSD to the existing mdraid. Also you may need to install grub boot loader on it:

grub-install /dev/sdX
