Cell needs to be setup before compute service list

[Dale Dude]

During deployI keep failing on:

TASK [nova : Waiting for nova-compute service up] *****************************************************

nova-api would produce this error:

If I run the task "Running nova simple cell setup" first in kolla-ansible/ansible/roles/nova/tasks/simple_cell_setup.yml the "Waiting for nova-compute service up" finishes.

Using ocata branch.

[Eduardo Gonzalez (egonzalez90)]

Dale, Ocata executes simple_cell_setup, first we wait until compute nodes are registered in nova, then run simple_cell_setup. Otherwise cell_setup raises error because no host are available.

In master there was an issue with cells but have a workaround merged. Can you please ensure rabbitmq containers are running, compute nodes too. Also, please ensure the code used is stable/ocata and not master(just in case are facing the master issue).

I am encountering this problem too.

kolla/ubuntu-binary* images does not seem to have stable versions. They have just masters and 3.0.0 or 4.*.* vs.

Eduardo would you please explain which code are you talking about?

Rg.

[Eduardo Gonzalez (egonzalez90)]

Hi Tuna, I'm talking about nova code itself.
Correct nova code without the bug is only installed on 3.0.3 images for source. In binary probably distributions backported the fix (not sure about this)

So, to migrate from newton to ocata, first need to upgrade newton to 3.0.3 and then to ocata 4.0.0.

Was the issue resolved? cell creation is working fine in both ocata and master branch ATM. Gates also work.

[Eduardo Gonzalez (egonzalez90)]

Due lack of information marking this bug as incomplete, feel free to re-open if still suffering the issue
