In your situation, I'd be tempted to not run the puppet agent in daemon mode at all so that you can retain full control of when the agents will check in. I can't see how the splay option will help avoid concurrent checkins:
Imagine HA node 1 is rebooted for whatever reason and comes back up at 12:00 at which point the puppet agent checks in due to its boot script running. Its splay parameter is set to true, its runinterval is the default 30m and its psuedo-random splay time is 5 mins. It will therefore next check in at 12:35. Now, HA node 2 just so happens to have checked in last at 11:55 and its pseudo-random splay time is 10 mins, so it's going to next check in at 12:35. As you, by definition, cannot control the pseudo-random delay time you cannot guarantee the availability of services managed by Puppet. So, instead of running puppet in daemon mode, I'd look to use something like mcollective to control when the agents check in with the master. Kind Regards, Matt.
