AFAIK, You can have these cluster combinations: 1 supervisor (control plane) 3 supervisors (control plane) 3 supervisors (control plane)+ >2 workers I think we’ll also have in the future: 1 supervisor (control plane)+ n workers The message should address all use-cases, maybe something like: "The cluster must contain either 1 supervisor (for Single Node OpenShift), 3 supervisors alone (so supervisors will run workloads), or 3 supervisors with an additional 2 workers at a minimum" I'm sure we can edit the wording to make it better though. With 2 nodes, cluster validation does not pass. The message is: "Clusters must have exactly 3 dedicated masters. Please either add hosts, or disable the worker host" With 3 nodes, cluster validation passes ok. With 4 nodes, and Role set to automatic cluster validation does not pass. The message is: "Clusters must have exactly 3 dedicated masters. Please either add hosts, or disable the worker host" With 5 nodes, cluster validation passes ok ( 3 nodes as Masters, 2 nodes Automatic ) With 5 nodes, ( 4 masters, 1 Automatic ): "Clusters must have exactly 3 dedicated masters. Please either add hosts, or disable the worker host" Marking this as Validated with versions : "release_tag":"v1.0.19.3" Assisted-ui-lib: 1.5.19 Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA.

message: "Clusters with less than 3 dedicated masters or a single worker are not supported" suggests that we support more than 3 If you attempt to set less (or more) than 3 masters - then the following warning is shown: Warning alert:Cluster is not ready to be installed yet The following requirements must be met: Clusters with less than 3 dedicated masters or a single worker are not supported. Please either add hosts, or disable the worker host The message should better indicate that we only support 3 masters, i.e. not less and not more.
