The issue was introduced with https://github.com/openshift/machine-config-operator/pull/2823/. The local nameserver is only prepended if the /var/run/NetworkManager/resolv.conf has a default search domain. https://github.com/openshift/machine-config-operator/blob/e1fbf07d69ca1176a523d0568260c76a6add9f9c/templates/common/on-prem/files/NetworkManager-resolv-prepender.yaml#L72 On PSI, the default resolv.conf looks like this: [core@mandre-psi-8x4w9-master-0 ~]$ cat /var/run/NetworkManager/resolv.conf # Generated by NetworkManager nameserver x.x.x.x And thus, the resulting resolv.conf generated by the NetworkManager-resolv-prepender script is: [core@mandre-psi-8x4w9-master-0 ~]$ cat /etc/resolv.conf # Generated by KNI resolv prepender NM dispatcher script nameserver x.x.x.x Removing the Triaged keyword because: * the QE automation assessment (flag qe_test_coverage) is missing Verified on: 4.10.0-0.nightly-2022-01-08-215919 CI run for profile 23_IPI on OSP16 & FIPS on & OVN & csidriver passed Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA.

Staring at 15th of Nov we see our OCP-4.10 deployments failing. We use nightly channel (registry.ci.openshift.org/ocp/release:4.10) to deploy 4.10 clusters. We use IPI deployment on top of OpenStack (RHOS-D & RHOS-C01 failing on both). The masters nodes are not joining the clusters. When observing console of the masters nodes, I see only four containers there, and I see errors in coredns-monitor container. I don't see any suspicions error on bootstrap, it is waiting for the masters to join, so it can schedule some workload on it. $ crictl ps CONTAINER IMAGE CREATED STATE NAME ATTEMPT POD ID 59f033eb5dd4c 232fb20b94dcad8030a95eef9c09c9f9f4e89f1685ac405ada44d0203d8d07c5 25 minutes ago Running coredns-monitor 0 8346d59db7493 2b1dfbd079c2c quay.io/openshift-release-dev/ocp-v4.0-art-dev@sha256:f0c1b89092c1966baa30586089f8698f2768b346717194f925cd80dfd84ed040 25 minutes ago Running coredns 0 8346d59db7493 ca7d0d4a174b7 232fb20b94dcad8030a95eef9c09c9f9f4e89f1685ac405ada44d0203d8d07c5 25 minutes ago Running keepalived-monitor 0 b0a7e4c78fef6 60594257d94dc quay.io/openshift-release-dev/ocp-v4.0-art-dev@sha256:3e96c1755163ecb2827bf4b4d1dfdabf2a125e6aeef620a0b8ba52d0c450432c 25 minutes ago Running keepalived 0 b0a7e4c78fef6 $ crictl logs 59f033eb5dd4c time="2021-11-18T16:56:56Z" level=error msg="Failed to build client config: invalid configuration: [unable to read client-cert /var/lib/kubelet/pki/kubelet-client-current.pem for default-auth due to open /var/lib/kubelet/pki/kubelet-client-current.pem: no such file or directory, unable to read client-key /var/lib/kubelet/pki/kubelet-client-current.pem for default-auth due to open /var/lib/kubelet/pki/kubelet-client-current.pem: no such file or directory]" What did you expect to happen? The cluster comes up as usually, with three master and three worker nodes. How to reproduce it (as minimally and precisely as possible)? $ openshift-install create cluster --dir cnv-qe.rhcloud.com/c01-lbednar --log-level debug Anything else we need to know? I attached, logs from bootstrap vm, from master-0, install log & install config.
