This makes it seem like the nodes are failing to get the correct hostnames/nodenames. So moving to rhcos tema to triage.
It looks like the problem occurs when either 1 - the dns server gets overloaded with queries, or 2 - reverse dns issues or 3 - IPV6 address resolution issues. I've moved my config to just using DNSMasq and tuned the config. Currently I can reliably deploy 4.3.19 Based on comment #4, it looks like this was related to DNS resolution problems. I don't think there is much that can be done on the RHCOS side for DNS resolution issues; closing as NOTABUG. If you think there is more that should be done here, please reopen. |
