[gpfsug-discuss] Node ‘crash and restart’ event using GPFS callback?

[Marc A Kaplan]

We have (pre)shutdown and pre(startup) ...
Trap  and record both... If you see a startup without a matching shutdown 
you know the shutdown never happened, because GPFS crashed.

Anyone crafted a good way to detect a node ‘crash and restart’ event using 
GPFS callbacks? I’m thinking “preShutdown” but I’m not sure if that’s the 
best. What I’m really looking for is did the node shutdown (abort) and 
create a dump in /tmp/mmfs
