So this is a bit after you pulled the plug on node 3?
Okay, could you also post the info I requested above plus the logs/journals (at least from the master node) around the time you pulled the plug.
Maybe upload /var/log/syslog here, we need as much information as possible so we can reproduce and fix this.

Yes, in seconds after pulled plug.
I disable ipv6 so there are many messages about iptables6 . I clean sysslog from iptables6-restore messages like under.
Dec 16 15:40:10 proxmox1test pve-firewall[2397]: status update error: iptables_restore_cmdlist: Try `ip6tables-restore -h' or 'ip6tables-restore --help' for more information.
What else do you need from: logs/journals ?
Syslog is under:
clean syslog
