Hello.
I am testing a case when I lost all my openstack cluster. I just have a full db backup and volumes(my storage node still alive).
I deploy a new cluster with same node's name after that I recover db from backup and the cluster is up but I cannot see my instances.
When I click on instance tab or volume tab, I see errors:

I hope you will share experiences.

I think this problem relates to keystone fernet and placement uuid. I will update later. Nguyen Huu Khoi

Hello.
I wrote these steps for people who met my scenario.
1. Deploy a new cluster with the same node name. 2. Restore DB as *https://docs.openstack.org/kolla-ansible/latest/admin/mariadb-backup-and-res... https://docs.openstack.org/kolla-ansible/latest/admin/mariadb-backup-and-restore.html* 3. Remove keystone, keystone_fernet, keystone_ssh and remove keystone volume. 4. Reconfigure keystone 4. Restart containers in compute, storage node and network node(if we have)
