[rdo-list] [TripleO] Newton large baremetal deployment issues

[Charles Short]

Hi Graeme,

Thanks for the reply.

I used these images -

http://buildlogs.centos.org/centos/7/cloud/x86_64/tripleo_images/newton/delorean/

I installed the stable repo following the documentation here -

http://docs.openstack.org/developer/tripleo-docs/installation/installation.html

for example -

sudo curl -L -o /etc/yum.repos.d/delorean-newton.repo https://trunk.rdoproject.org/centos7-newton/current/delorean.repo

sudo curl -L -o /etc/yum.repos.d/delorean-deps-newton.repo http://trunk.rdoproject.org/centos7-newton/delorean-deps.repo


The difficulty I am having is that when I test with a small deployment
all works fine. So you would assume just adding more compute nodes would
not be an issue.
Testing this is painful due to the time it takes for a large deployment
to fail. It seems to be only scale that is the issue.

I will try and get you some logs

Regards

Charles
