I have 2 host in a cluster. I migrate all the VM and containers to 1 host then reboot the second host. After 1 minute the first host also reboots and I lose the datacenter until it comes back and of course all vm and containers are rebooted.
How do I avoid main host hosting the current vm not to reboot when I reboot the second host to apply upgrades for example.

Im a proxmox noob by the way and Im learning but I fell in love with it hehe. I just want to remove all these little quirks before i go in prod
