I have a puppet master server that will be down for hardware maintenance.
I would like to know if puppet agents are still going to run successfully while the puppet master is down.

I am using open source puppet.

Puppet uses a pull model.

The interval that puppet executes is defined in the /etc/puppet/puppet.conf file. The default is 30 minutes.

You can simulate what will happen when puppet attempts to execute the puppet run, and no master is available.

puppet agent --verbose --noop --test --no-daemonize --server=foo.bar

Hint: You will see the following output

...
Error: Could not retrieve catalog from remote server: Connection refused - connect(2)
Warning: Not using cache on failed catalog
Error: Could not retrieve catalog; skipping run
Error: Could not send report: Connection refused - connect(2)

The puppet master won't show any failures during the time that it is down, instead it will just have a gap in the history.

To clarify (or perhaps a follow up question): will the compiled catalog that each node already has continue to run every 30 minutes, or will it simply fail because the puppet master is no longer reachable?
