Puppet users - Sep 2013 - Puppet Master fails when dashboard is unreachable

I would like to know if anyone has seen this before or has any suggestions.

After a power cut recently we were bringing our farm back on line, and our 
dashboard server (separate to our puppet master) was not online yet as 
reporting at this point was not considered critical. 
However, we noticed that none of our critical machines completed their 
puppet runs. It appears to us that puppet freezes when its unable to get a 
response back from the dashboard, and never times out.

As soon as we brought the dashboard back online everything started working 
again.

Cheers
Chris

Hi,
I guess the puppetdb is running on the dashboard server aswell? I think the
storeconfigs/exported ressources will fail with the database unavailable.

Hi Marcus

We aren''t running PuppetDB, so hoping that shouldn''t effect
anything?

Hi Chris,

We''ve encountered this issue before.

For us it''s due to using dashboard as an ENC. When the master compiles
the catalog it goes off to the ENC and gets node details.  When the dashboard is
down obviously the master can''t retrieve what it needs so the catalog
compilation fails.

To test it comment out the lines to do with node_terminus in puppet.conf. I
think there are two. Restart the master then switch off the dashboard. See if
the puppet agent -t works.

We weren''t actually dashboard for the ENC capabilities so we removed
the two lines and all was ok.


AFAIK just using the reporting functionality will not stop the puppet run when
the dashboard is down.

Cheers,  Josh
