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

[Oesterlin, Robert]

Actually, I think “preShutdown” will do it since it passes the type of shutdown “abnormal” for a crash to the call back - I can use that to send a Slack message.

mmaddcallback node-abort --event preShutdown --command /usr/local/sbin/callback-test.sh --parms "%eventName %reason"

and you get either:

preShutdown normal
preShutdown abnormal

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.
