In this state "hard restart" is always necessary.

But unfortunatelly the server was in unusable state, was not responding to keystrokes, after 15 minutes of waiting just some enter keys came through. I went physically to "prox3" server, thinking that i can do something about the situation via terminal. Yesterday we performed a test - we restarted server "backup" and in few seconds we lost the connection with servers "pve, prox3, prox2-brno". When we restart node or corosing on some host (systemctl restart corosync), then on some other nodes ethernet adapter crashes and does not recover himself. We are facing pretty curios troubles in Proxmox cluster.
