It depends. For e.g a) Nova Compute: then you can configure the triggering of evacauation and migration procedure of the VMs to an healthy compute node. You can read more about it here: https://docs.openstack.org/nova/rocky...

b) Controllers: They run in a quorum and by deafult there are 3 running instances. So failure of any one of the server causes no issues.

c) Storage ( for e.g. volume storage in CEPH): Here the data is duplicated to additional server nodes in a cluster by replication or erasure coding. In ceph by default there are three server nodes in a cluster. So even if any one of the nodes fails, VM can still find its data from the remaining two health nodes of the cluster

Considering the following use case below, what would be default behaviour: Step-1) All three controller up and running Step-2) Shutdown 1st controller Step-3) Shutdown 2nd Controller: Cluster Quorum destroyed Step-4) Bring up 2nd controller:

Question: In step-4 , will pacemaker create the cluster automatically in step-4

I am exploring ways to deploy a multi-site OpenStack deployment with controllers at one site and with multiple geographically located compute and storage nodes. For e.g: Site-1: 3 Controllers, some computes and storage Site-2: Compute, Storage Site-3: Compute, Storage ..and so on.
Considering this as a theoretical viable solution, what are some of the areas one should focus to have this up and running?

I investigated further by comparing the logs with a working installation.

it seems that the following folders/files are not generated in my case: /opt/stack/tacker-horizon/tacker_horizon/locale /opt/stack/tacker-horizon/tacker_horizon/__init__.pyc /opt/stack/tacker-horizon/tacker_horizon/openstack_dashboard/dashboards/nfv/__init__.pyc /opt/stack/tacker-horizon/tacker_horizon/openstack_dashboard/dashboards/nfv/locale

Please let me know if there is anything wrong.

After installing devstack ( stable/newton) i ovserve that horizon is not displaying the a) images b) instances Going through the horizon logs i observe the following:

Any idea what could be the reson?
