Mihai, I am putting the list here as well...
No I didn't add the [placement] section in nova.conf on the controller
but adding it only on the compute node brought it online.
I don't know yet if I can spawn an instance and if what you are saying
is mandatory in Ocata in order to spawn one since I haven't reached that
part of the installation guide. The verification though of the compute
services went OK as supposed to by the installation guide.
Best,
George
Hi,
Did you also add the [placement] section in nova.conf on the
controller?
Also in Ocata AFAIK you also need to create cell_v2 with nova-manage
or else you wont be able to spawn instances.
But first add the placement section on the controller too in
nova.conf
and the computes shoukd come online.

All,
I am trying to deploy OpenStack Ocata on bare metal servers

Unfortunately I have stuck at deploying the Compute Node due to
the following
error in the logs when I try to start nova-compute service:

Did it actually kill the nova-compute service or just complain in
the
logs? The release notes for nova in Ocata say:
The nova-compute worker now communicates with the new
placement API
service. Nova determines the placement API service by
querying the
OpenStack service catalog for the service with a service
type of
placement. If there is no placement entry in the service
catalog,
nova-compute will log a warning and no longer try to
reconnect to the
placement API until the nova-worker process is restarted.

Hi Chris,
it is constantly printing this output in the log and also prevents
the openstack-nova-compute.service
from being shown as Active (running) when doing a "systemctl status
openstack-nova-compute.service"
There is already a proposed bug fix
https://review.openstack.org/#/c/440140/ [2] which seems to solve
this problem
For reference I ve added the following in the "placement" section
of nova.conf in the compute node
[placement]
# ...
os_region_name = RegionOne
project_domain_name = Default
user_domain_name = Default
project_name = service
auth_type = password
username = nova
password = NOVA_PASS
auth_url = http://controller:35357/v3 [3]
Best regards,
George
