Warning: Not using cache on failed catalog. Why?

I want to use Puppet on an unreliable network, and I have been testing what would happen if the Master is down/uncontactable. The Agent does this:

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)

How do I get puppet to automatically use the cached catalog when it is unable to contact the master, or the master is unable to generate a new catalog? I don't want to have to manually log on to the server and run agent --usecachedcatalog every time.

The default of use_cached_catalog is false as you've already noticed yourself (see docs) but you can add use_cached_catalog = true in your agent configuration (default: /etc/puppet/puppet.conf) to overwrite this default.

The agent will then use the cached catalog by default. Note that you can still overwrite this setting when running puppet from the commandline ( with--use_cached_catalog and --no-use_cached_catalog)


Thanks for pointing out I made a mistake. It looks you are right and --use_cached_catalog will always use the cached version even if a new catalog would compile. So setting this option is not what you want.

The only reason I currently see - but I may be wrong here, too - is that usecacheonfailure is false (while true is the default), probably set indirectly with --ignorecache or --test? Can you please verify (with puppet agent --configprint usecacheonfailure)

> The agent will then use the cached catalog by default. Where did I say I wanted to use the cached catalogue by default? Did you even read the question?

have you read the update yet? I have not tried to reproduce the issue so far, so I'd be interested if it really ignores the cached catalog even tough `usecacheonfailure` is set.
