cluster issues - second node lost

[kitkat]

hi all,
I have had issues with my cluster of 2 nodes, so today, i wanted to go back to a single node (2 individuals since the second one is having issues).
So I did not know how to disconnect the second node so I disabled the eno4 which is the interface between the 2 nodes (10.99.99.0/24).
Main management network is 10.0.9.0/24 (.3 is second node bad one, and .4 is first good node)
Now I can no login to the web interface, it keeps failing:

How do I brake the nodes and gain access to individuals separately via web interface (10.0.9.4)?

i tail -f the syslog and get what you see in picture attach

You need at least 3 hosts for a cluster. When you got just two and one is off, then you get into a split brain situation as there is no quorum so the remaining node will stop working too.
To fix that you would need to add a third PVE node or at least add a small thin client or SBC as a qdevice to act as a third voter: https://pve.proxmox.com/wiki/Cluster_Manager#_corosync_external_vote_support
