Can we have undercloud in HA mode? Undercloud is usually a single node installation. If undercloud goes down Overcloud can work normally unless nothing happens to it. But what if undercloud is not recoverable soon enough. Could someone elaborate me on how can I put undercloud in HA mode ? What are the things necessary to do this?

I might be wrong but based on what you asked I figure out that undercloud is an abbreviation where the Cloud OS is deployed in a single machine.

Now if I am right on what I stated above you need to install entire openstack in HA mode in a single machine, which is possible then can you please explain the usecase as to what will happen when the undercloud or one of its service goes to which node would take it place?

Once you tell me this I can tell you what needs to be done and how can we achieve it because as far as setting up of openstack is concerned it can be done on a single node without any major issue.
