Hi Winicius

I checked the globals.yml and my configuration for cinder and nova keyring are below

ceph_cinder_keyring: "client.{{ ceph_cinder_user }}.keyring"

ceph_nova_keyring: "{{ ceph_cinder_keyring }}"

The filepath is rightly in /etc/kolla/config/nova/ceph.client.cinder.keyring 

But nova_compute container don’t goes up with the error below

ERROR MissingRequiredSource: /var/lib/kolla/config_files/ceph.client.cinder.keyring file is not found

Any idea ?

Kind Regards

Luca

Subject: Re: Kolla-ansible Openstack deployment failed in nova-compute task

Hi Luca,

Check `ceph_nova_keyring` and `ceph_cinder_keyring` variables in your globals.yml.

Kolla adds "ceph" at the start of the variable name to find the file in node_config_directory. So, if you have

ceph_nova_keyring: client.cinder.keyring

The filepath must be "/etc/kolla/config/nova/ceph.client.cinder.keyring", for example.

Regards,

Winicius.

Hi guys,

In my first openstack deploy I facing an error in deployment phase. The bootstrap-servers phase and the prechecks phase working fine but the deploy phase stop to work in nova-compute task deployment with the following error

[ERROR]: Task failed: Action failed.
Origin: /root/kolla-venv/share/kolla-ansible/ansible/roles/nova-cell/tasks/wait_discover_computes.yml:24:7

22     expected_compute_service_hosts: "{{ virt_compute_service_hosts + ironic_compute_service_hosts }}"
23   block:
24     - name: Waiting for nova-compute services to register themselves

looking for the nova-compute docker logs I found this event

ERROR MissingRequiredSource: /var/lib/kolla/config_files/ceph.client.cinder.keyring file is not found

I would you like to point out that the ceph keyring are created and copied to /etc/koll/config/nova in deployment host and /etc/ceph in all openstack host.
Some one could help me for fix the issue ?

Regards
Luca
