What I'd like to do, which I haven't put time into figuring out, is how to setup a persistent trigger that can run when ANY node goes into drain state. Let me know if you figure that out. As you can see above, the trigger has to be setup by the slurm user.

strigger takes a "--flags=perm" option, which makes the trigger
permanent and doesn't purge it after the event happened. So it doesn't
need tb re-armed in the trigger script for the next event.

Also, not specifying any job id nor node name in the strigger command
will make the trigger apply to all nodes. That's how we set our
default "down" trigger for all nodes on our cluster:
# su -s /bin/bash -c "strigger --set --down
--program=/share/admin/scripts/slurm/triggers/down.sh --flags=perm"

Also note that the script given to "--program" needs to be executable
by user Slurm on the controller node(s).
