FailedQA: Returning to ASSIGNED Although the documentation in the latest spin of the documentation is correct, Please add a note about the interaction between worker nodes and infrastructure nodes (i.e. that infrastructure nodes can be used as worker nodes to provide HA with "no single point of failure" if only 1 worker node is deployed as alluded to in the OCP docs). I'm not sure I understand this. Can you please clarify for me? * Do you have to configure the infrastructure nodes in any special way for them to be used as worker nodes? * Doesn't that contradict the description of infrastructure nodes in the OCP HA table, which says "Only the default configuration is supported"? Or is that referring to something else? * Wouldn't it be better to recommend at least two worker nodes for HA? Your suggestions seem reasonable to me, Routing to dgao for a authoritative response. The infrastructure node can actually be used as worker nodes as well. There are no special configuration that's needed to enable them as worker nodes. So technically with the default configuration, there will be 3 worker nodes available. One dedicated node + 2 infrastructure nodes that double down as worker nodes. Additional information is in latest doc spin, Works for me, moving to VERIFIED Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA.
