Yes, sure. I'm really to have to 2 differents sources of verification, with different path/software, to avoid this kind of bug.
(shit happens, murphy law ;)

as we say in French "ceinture & bretelles" -> "belt and braces"


BTW,
a user have reported new corosync problem here:
https://forum.proxmox.com/threads/proxmox-6-2-corosync-3-rare-and-spontaneous-disruptive-udp-5405-storm-flood.75871
(Sound like the bug that I have 6month ago, with corosync bug flooding a lof of udp packets, but not the same bug I have here)

AFAIK Thomas already has patches to implement active fencing. 

But IMHO this will not solve the corosync problems..
