Thank you for the clarification. So in order to deploy glance on multiple nodes, I need to first set up an NFS storage then specify the shared path either by overriding the content of ansible/group_vars/all.yml or by adding glance_file_datadir_volume:NFS_PATH in globals.yml ? Which NFS tool do you think I should use? Thank you again. Regards On Thu, 21 Jul 2022 at 10:42, Pierre Riteau <pierre@stackhpc.com> wrote:
With the default backend (file), Glance is deployed on a single controller, because it uses a local Docker volume to store Glance images. This is explained in the documentation [1]: "By default when using file backend only one glance-api container can be running". See also the definition of glance_api_hosts in ansible/group_vars/all.yml.
If you set glance_file_datadir_volume to a non-default path, it is assumed to be on shared storage and kolla-ansible will automatically use all glance-api group members.
You can also switch to another backend such as Ceph or Swift.

I've deployed openstack xena using kolla ansible on a centos 8 stream cluster, using two controller nodes, however I found out after the deployment that glance api is not available in one node, I tried redeploying but I got the same behavior, although the deployment finished without displaying any error.
Thank you. Regards
