[ClusterLabs] Correctly stop pacemaker on 2-node cluster with SBD and failed devices?

[Strahil Nikolov]

Maybe you can try:
while true ; do echo '0' > /proc/sys/kernel/nmi_watchdog ; sleep 1 ; done
and in another shell stop pacemaker and sbd.
I guess the only way to easily reproduce is with sbd over iscsi.

No it won't. It will still stop pacemaker.

What makes you think I am not aware of it?

can you suggest the steps to avoid it?
