Description of problem: If one chooses to configure NTP servers, packstack will fail if ntpd is already running. The reason behind this is that both are sharing the same socket. Therefore ntpdate will print an error and return exit code 1, but packstack / puppet are expecting exit code 0. Version-Release number of selected component (if applicable): openstack-packstack-2012.2.2-0.7.dev346.el6.noarch How reproducible: Always Steps to Reproduce: 1. Have ntpd already running (with default server configuration or whatever) 2. Tell packstack to configure NTP servers 3.

Good point, patch is working, but it could be done easier [1] as puppet provides such function. [1] http://www.puppetcookbook.com/posts/ensure-service-is-stopped.html
(In reply to comment #3) > Good point, patch is working, but it could be done easier [1] as puppet > provides such function. > > [1] http://www.puppetcookbook.com/posts/ensure-service-is-stopped.html Sure, but ntpd is already defined (with the opposite value for "ensure") and puppet won't allow to define it a second time.

This is also a problem if the controller is also the NTP server. Puppet stops ntpd then runs ntpdate and it fails. A work around is to leave ntpd running and run ntpdate -bu <server>. This allows ntpdate to sync against a running ntpd on the same system. In small POC environments where a time server may not be reachable, this becomes a problem as a dedicated NTP server is needed. Instead, the controller can be used to setup ntpd on it's own pseudo clock to at least keep all the OpenStack systems in sync, regardless if it can reach an external ntpd server. Example configuration to accomplish this: server 127.127.1.0 fudge 127.127.1.0 stratum 10 See Bug 1134613
