Host failure caused reboot on other host in 2 node cluster

[hgztk]

Hello,
We deployed a cluster consists 2 hosts. Yesterday one of them suddenly rebooted itself (might be caused by a hardware malfunction or power outage), after that the other one. We conducted few tests after incident occurred, observed that when the first node was rebooted, the second node also triggered to reboot.
Do you have any suggestion for resolve that issue?

Thanks in advance.

There is no such thing as a primary and secondary node. All nodes are equal: https://pve.proxmox.com/pve-docs/pve-admin-guide.html#_quorum
This is a very common issues with two-node clusters: when one node goes down (or a network issue() the other node is (also) not quorate. Please search the forum and read about adding a third vote: https://pve.proxmox.com/pve-docs/pve-admin-guide.html#_qdevice_technical_overview

Sorry about wrong term. We added third node, now it's working as it should. Thanks for your suggestions.
