Description Greg Blomquist 2011-12-16 16:05:07 UTC 
From a aeolus-configserver-setup log:

err: /Stage[main]/Apache::Base/Exec[graceful-apache]: Failed to call refresh: /sbin/service httpd graceful returned 1 instead of one of [0] at /usr/share/aeolus-configserver/configure/puppet/modules/apache/manifests/init.pp:41


Version-Release number of selected component (if applicable):
aeolus-configserver-0.4.3-2.fc15.noarch


How reproducible:
Intermittent.  Puppet is a non-deterministic finite state machine.  So, sometimes this error occurs, and sometimes it doesn't.


Steps to Reproduce:
1. run aeolus-configserver-setup from the command line of a config server


Actual results:
err: /Stage[main]/Apache::Base/Exec[graceful-apache]: Failed to call refresh: /sbin/service httpd graceful returned 1 instead of one of [0] at /usr/share/aeolus-configserver/configure/puppet/modules/apache/manifests/init.pp:41


Expected results:
Apache starts up after the setup script runs.


The fix is to force some aspects of the puppet code to be more deterministic by adding in "notify => Exec['graceful-apache']" to several of the puppet commands.  This will force several things to complete before attempting to notify the restart of apache.
