This looks a lot like the issues I saw when the host firewall (iptables) was blocking another OKD all-in-one-host install script [1].
Disabling iptables allowed the installation to continue for my proof of concept "cluster".

[1]https://github.com/gshipley/installcentos

The other error I had with [1] was it was trying to install a couple of packages (zile and python2-pip) from EPEL with the repo disabled.

Shirly,

Oh and I should mention that I did verify that NetworkManager was installed on the master0 VM and enabled/started the second go around.  So that service is there and running. 

# systemctl list-unit-files | grep Network
dbus-org.freedesktop.NetworkManager.service                             enabled
NetworkManager-dispatcher.service                                       enabled
NetworkManager-wait-online.service                                      enabled
NetworkManager.service                                                  enabled

Shirly,

I appreciate the help with this.  Unfortunately I am still running in to the same problem.  So far I've tried to install/enable/start NetworkManager on the existing "master0" server and re-ran the plans from the installer VM.  I ran in to the same problem waiting for control plane pods and same errors in syslog.

So I wiped everything out, killed the template along with the installer and master VMs.  On oVirt engine (I am running 4.3.3.7-1 stable) I did have ovirt-engine-metrics-1.3.0x rpm installed, no yum updates available on an update check.  So I installed http://resources.ovirt.org/pub/yum-repo/ovirt-release43-pre.rpm then proceeded to install the latest version of ovirt-engine-metrics which gave me: ovirt-engine-metrics-1.3.1-1.el7.noarch on hosted engine. 

After that package was installed I proceeded to follow steps from beginning outlined at: https://ovirt.org/documentation/metrics-install-guide/Installing_Metrics_Store.html -- I ran in to the docker check issue again (same as my initial email) so I disabled that and again got as far as starting control plane pods before failure. 

Not sure where to go from here at this point.  The only thing I can think of that I did differently vs the instructions outlined above is that I have not crated the wildcard DNS record, however I did set configs to create /etc/hosts entries and they /etc/hosts on the machines have the proper IPs assigned for all hostnames (automatically added by the ansible plays).

Any ideas how I can get past the plane pods issue?

Thanks!

Hi,

The latest release of 4.3.z should already include a fix for this issue, ovirt-engine-metrics-1.3.1 rpm.

The issue is that it requires the NetworkManagar to be installed, running and enabled for it to work.

You can install it manually on the master0 vm , start and enable it or you can also install the updated rpm from the nightly builds if your environment is oVirt 4.2.z:

I managed to get past that but am running in to another problem later in the process on the control plane pods to appear task.   I thought perhaps a glitch in the process from the failed docker step previously so after a few more runs I tried killing everything and restarting the metrics process again from the very beginning and end up hitting the same issue with control plane pods even though all other steps/tasks seem to be working.

I'm just getting this:

Hi Jayme,

Thank you for reaching out.
Please try rerunning the ansible playbook.
If this doesn't work, try adding to the integ.ini in the metrics vm 
openshift_disable_check=docker_storage
and rerun the ansible playbook again.

Please update how it goes.

The execution of "install_okd.yaml" includes checks designed to fail early if the requirements of the playbook are not met. One or more of these checks failed. To disregard these results,explicitly disable checks by setting an Ansible variable:
   openshift_disable_check=docker_storage
Failing check names are shown in the failure details above. Some checks may be configurable by variables if your requirements are different from the defaults; consult check documentation.
Variables can be set in the inventory or passed on the command line using the -e flag to ansible-playbook.
