Large memory system might need hours to finish the vmcore capturing
so 60 seconds is not enough, could you help to increase the default
value? I think there's no side effect to set it as INT_MAX?
I'm a lot confused with the option "pcmk_reboot_timeout".
In kdump environment, fence_kdump_send is running background and send
an acknowledge message out every 10 seconds (by default) indefinately
(by default).
So how does the timeout works?
1. Will it be reset and count down again when it receives a valid
message from the crashed node?
2. Will fence kdump agent wait for time out after the very first
message is received?
