Sadly the log node does not have enough ram to run a full ansible run.
Ansible 2.x requires more ram than one would expect, especially when the
inventory gets large. this change moves the deploy node to infra1 as it
will already have the ram needed to run the playbooks. Additionally the
container storage for infra nodes was too small which forces builds into
error. The default storage for VMs has been set to 90GiB each and the
preseed will create a logical volume for VMs mounted at /var/lib/lxc.
While the limited ram works well for the VMs and within a running
deployment of OSA, ansible-playbook is subject to crash like so:
An exception occurred during task execution. To see the full traceback,
use -vvv. The error was: OSError: [Errno 12] Cannot allocate memory
fatal: [infra1_cinder_api_container-b38b47ea]: FAILED! =>
{"failed": true, "msg": "Unexpected failure during module execution.", "stdout": ""}
So infra nodes have had the memory constraint raised to 8GiB
