What is "fencing failed"? What happens if fencing failed?
So if pcmk_reboot_timeout is 60 seconds, and dump did not finish in
60 seoncds, what happens? Crashed node will be power cycled and kdump
will fail?
It means that cluster will try next attempt to reboot/power off the
machine. Usually there is an additional layer (e.g. ipmi, power
switches) which just reboot machine, so it can not disturb running
cluster (corrupt shared data).
This situation is not fence_kdump specific, it can also happens on
hardware fence devices e.g. when you can not login.
