Chapter 5. Troubleshooting the installation 5.1. Troubleshooting the installation program workflow Before troubleshooting the installation environment, it is critical to understand the overall flow of the installer-provisioned installation on bare metal. The following diagrams illustrate a troubleshooting flow with a step-by-step breakdown for the environment. Workflow 1 of 4 illustrates a troubleshooting workflow when the install-config.yaml file has errors or the Red Hat Enterprise Linux CoreOS (RHCOS) images are inaccessible. See Troubleshooting install-config.yaml for troubleshooting suggestions. Workflow 2 of 4 illustrates a troubleshooting workflow for bootstrap VM issues , bootstrap VMs that cannot boot up the cluster nodes , and inspecting logs . When installing an OpenShift Container Platform cluster without the provisioning network, this workflow does not apply. Workflow 3 of 4 illustrates a troubleshooting workflow for cluster nodes that will not PXE boot . If installing using Redfish virtual media, each node must meet minimum firmware requirements for the installation program to deploy the node. See Firmware requirements for installing with virtual media in the Prerequisites section for additional details. Workflow 4 of 4 illustrates a troubleshooting workflow from a non-accessible API to a validated installation . 5.2. Troubleshooting install-config.yaml The install-config.yaml configuration file represents all of the nodes that are part of the OpenShift Container Platform cluster. The file contains the necessary options consisting of but not limited to apiVersion , baseDomain , imageContentSources and virtual IP addresses. If errors occur early in the deployment of the OpenShift Container Platform cluster, the errors are likely in the install-config.yaml configuration file. Procedure Use the guidelines in YAML-tips . Verify the YAML syntax is correct using syntax-check . Verify the Red Hat Enterprise Linux CoreOS (RHCOS) QEMU images are properly defined and accessible via the URL provided in the install-config.yaml . For example: USD curl -s -o /dev/null -I -w "%{http_code}\n" http://webserver.example.com:8080/rhcos-44.81.202004250133-0-qemu.<architecture>.qcow2.gz?sha256=7d884b46ee54fe87bbc3893bf2aa99af3b2d31f2e19ab5529c60636fbd0f1ce7 If the output is 200 , there is a valid response from the webserver storing the bootstrap VM image. 5.3. Troubleshooting bootstrap VM issues The OpenShift Container Platform installation program spawns a bootstrap node virtual machine, which handles provisioning the OpenShift Container Platform cluster nodes. Procedure About 10 to 15 minutes after triggering the installation program, check to ensure the bootstrap VM is operational using the virsh command: USD sudo virsh list Id Name State -------------------------------------------- 12 openshift-xf6fq-bootstrap running Note The name of the bootstrap VM is always the cluster name followed by a random set of characters and ending in the word "bootstrap." If the bootstrap VM is not running after 10-15 minutes, verify libvirtd is running on the system by executing the following command: USD systemctl status libvirtd ● libvirtd.service - Virtualization daemon Loaded: loaded (/usr/lib/systemd/system/libvirtd.service; enabled; vendor preset: enabled) Active: active (running) since Tue 2020-03-03 21:21:07 UTC; 3 weeks 5 days ago Docs: man:libvirtd(8) https://libvirt.org Main PID: 9850 (libvirtd) Tasks: 20 (limit: 32768) Memory: 74.8M CGroup: /system.slice/libvirtd.service ├─ 9850 /usr/sbin/libvirtd If the bootstrap VM is operational, log in to it. Use the virsh console command to find the IP address of the bootstrap VM: USD sudo virsh console example.com Connected to domain example.com Escape character is ^] Red Hat Enterprise Linux CoreOS 43.81.202001142154.0 (Ootpa) 4.3 SSH host key: SHA256:BRWJktXZgQQRY5zjuAV0IKZ4WM7i4TiUyMVanqu9Pqg (ED25519) SSH host key: SHA256:7+iKGA7VtG5szmk2jB5gl/5EZ+SNcJ3a2g23o0lnIio (ECDSA) SSH host key: SHA256:DH5VWhvhvagOTaLsYiVNse9ca+ZSW/30OOMed8rIGOc (RSA) ens3: fd35:919d:4042:2:c7ed:9a9f:a9ec:7 ens4: 172.22.0.2 fe80::1d05:e52e:be5d:263f localhost login: Important When deploying an OpenShift Container Platform cluster without the provisioning network, you must use a public IP address and not a private IP address like 172.22.0.2 . After you obtain the IP address, log in to the bootstrap VM using the ssh command: Note In the console output of the step, you can use the IPv6 IP address provided by ens3 or the IPv4 IP provided by ens4 . USD ssh core@172.22.0.2 If you are not successful logging in to the bootstrap VM, you have likely encountered one of the following scenarios: You cannot reach the 172.22.0.0/24 network. Verify the network connectivity between the provisioner and the provisioning network bridge. This issue might occur if you are using a provisioning network. You cannot reach the bootstrap VM through the public network. When attempting to SSH via baremetal network, verify connectivity on the provisioner host specifically around the baremetal network bridge. You encountered Permission denied (publickey,password,keyboard-interactive) . When attempting to access the bootstrap VM, a Permission denied error might occur. Verify that the SSH key for the user attempting to log in to the VM is set within the install-config.yaml file. 5.3.1. Bootstrap VM cannot boot up the cluster nodes During the deployment, it is possible for the bootstrap VM to fail to boot the cluster nodes, which prevents the VM from provisioning the nodes with the RHCOS image. This scenario can arise due to: A problem with the install-config.yaml file. Issues with out-of-band network access when using the baremetal network. To verify the issue, there are three containers related to ironic : ironic ironic-inspector Procedure Log in to the bootstrap VM: USD ssh core@172.22.0.2 To check the container logs, execute the following: [core@localhost ~]USD sudo podman logs -f <container_name> Replace <container_name> with one of ironic or ironic-inspector . If you encounter an issue where the control plane nodes are not booting up from PXE, check the ironic pod. The ironic pod contains information about the attempt to boot the cluster nodes, because it attempts to log in to the node over IPMI. Potential reason The cluster nodes might be in the ON state when deployment started. Solution Power off the OpenShift Container Platform cluster nodes before you begin the installation over IPMI: USD ipmitool -I lanplus -U root -P <password> -H <out_of_band_ip> power off 5.3.2. Inspecting logs When experiencing issues downloading or accessing the RHCOS images, first verify that the URL is correct in the install-config.yaml configuration file. Example of internal webserver hosting RHCOS images bootstrapOSImage: http://<ip:port>/rhcos-43.81.202001142154.0-qemu.<architecture>.qcow2.gz?sha256=9d999f55ff1d44f7ed7c106508e5deecd04dc3c06095d34d36bf1cd127837e0c clusterOSImage: http://<ip:port>/rhcos-43.81.202001142154.0-openstack.<architecture>.qcow2.gz?sha256=a1bda656fa0892f7b936fdc6b6a6086bddaed5dafacedcd7a1e811abb78fe3b0 The coreos-downloader container downloads resources from a webserver or from the external quay.io registry, whichever the install-config.yaml configuration file specifies. Verify that the coreos-downloader container is up and running and inspect its logs as needed. Procedure Log in to the bootstrap VM: USD ssh core@172.22.0.2 Check the status of the coreos-downloader container within the bootstrap VM by running the following command: [core@localhost ~]USD sudo podman logs -f coreos-downloader If the bootstrap VM cannot access the URL to the images, use the curl command to verify that the VM can access the images. To inspect the bootkube logs that indicate if all the containers launched during the deployment phase, execute the following: [core@localhost ~]USD journalctl -xe [core@localhost ~]USD journalctl -b -f -u bootkube.service Verify all the pods, including dnsmasq , mariadb , httpd , and ironic , are running: [core@localhost ~]USD sudo podman ps If there are issues with the pods, check the logs of the containers with issues. To check the logs of the ironic service, run the following command: [core@localhost ~]USD sudo podman logs ironic 5.4. Investigating an unavailable Kubernetes API When the Kubernetes API is unavailable, check the control plane nodes to ensure that they are running the correct components. Also, check the hostname resolution. Procedure Ensure that etcd is running on each of the control plane nodes by running the following command: USD sudo crictl logs USD(sudo crictl ps --pod=USD(sudo crictl pods --name=etcd-member --quiet) --quiet) If the command fails, ensure that Kubelet created the etcd pods by running the following command: USD sudo crictl pods --name=etcd-member If there are no pods, investigate etcd . Check the cluster nodes to ensure they have a fully qualified domain name, and not just localhost.localdomain , by using the following command: USD hostname If a hostname is not set, set the correct hostname. For example: USD sudo hostnamectl set-hostname <hostname> Ensure that each node has the correct name resolution in the DNS server using the dig command: USD dig api.<cluster_name>.example.com ; <<>> DiG 9.11.4-P2-RedHat-9.11.4-26.P2.el8 <<>> api.<cluster_name>.example.com ;; global options: +cmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 37551 ;; flags: qr aa rd ra; QUERY: 1, ANSWER: 1, AUTHORITY: 1, ADDITIONAL: 2 ;; OPT PSEUDOSECTION: ; EDNS: version: 0, flags:; udp: 4096 ; COOKIE: 866929d2f8e8563582af23f05ec44203d313e50948d43f60 (good) ;; QUESTION SECTION: ;api.<cluster_name>.example.com.

This IP address should reside on the baremetal network. 5.5. Troubleshooting a failure to initialize the cluster The installation program uses the Cluster Version Operator to create all the components of an OpenShift Container Platform cluster. When the installation program fails to initialize the cluster, you can retrieve the most important information from the ClusterVersion and ClusterOperator objects. Procedure Inspect the ClusterVersion object by running the following command: USD oc --kubeconfig=USD{INSTALL_DIR}/auth/kubeconfig get clusterversion -o yaml Example output apiVersion: config.openshift.io/v1 kind: ClusterVersion metadata: creationTimestamp: 2019-02-27T22:24:21Z generation: 1 name: version resourceVersion: "19927" selfLink: /apis/config.openshift.io/v1/clusterversions/version uid: 6e0f4cf8-3ade-11e9-9034-0a923b47ded4 spec: channel: stable-4.1 clusterID: 5ec312f9-f729-429d-a454-61d4906896ca status: availableUpdates: null conditions: - lastTransitionTime: 2019-02-27T22:50:30Z message: Done applying 4.1.1 status: "True" type: Available - lastTransitionTime: 2019-02-27T22:50:30Z status: "False" type: Failing - lastTransitionTime: 2019-02-27T22:50:30Z message: Cluster version is 4.1.1 status: "False" type: Progressing - lastTransitionTime: 2019-02-27T22:24:31Z message: 'Unable to retrieve available updates: unknown version 4.1.1 reason: RemoteFailed status: "False" type: RetrievedUpdates desired: image: registry.svc.ci.openshift.org/openshift/origin-release@sha256:91e6f754975963e7db1a9958075eb609ad226968623939d262d1cf45e9dbc39a version: 4.1.1 history: - completionTime: 2019-02-27T22:50:30Z image: registry.svc.ci.openshift.org/openshift/origin-release@sha256:91e6f754975963e7db1a9958075eb609ad226968623939d262d1cf45e9dbc39a startedTime: 2019-02-27T22:24:31Z state: Completed version: 4.1.1 observedGeneration: 1 versionHash: Wa7as_ik1qE= View the conditions by running the following command: USD oc --kubeconfig=USD{INSTALL_DIR}/auth/kubeconfig get clusterversion version \ -o=jsonpath='{range .status.conditions[*]}{.type}{" "}{.status}{" "}{.message}{"\n"}{end}' Some of most important conditions include Failing , Available and Progressing .

Troubleshooting a failure to fetch the console URL The installation program retrieves the URL for the OpenShift Container Platform console by using [route][route-object] within the openshift-console namespace. If the installation program fails the retrieve the URL for the console, use the following procedure. Procedure Check if the console router is in the Available or Failing state by running the following command: USD oc --kubeconfig=USD{INSTALL_DIR}/auth/kubeconfig get clusteroperator console -oyaml apiVersion: config.openshift.io/v1 kind: ClusterOperator metadata: creationTimestamp: 2019-02-27T22:46:57Z generation: 1 name: console resourceVersion: "19682" selfLink: /apis/config.openshift.io/v1/clusteroperators/console uid: 960364aa-3ae1-11e9-bad4-0a97b6ba9358 spec: {} status: conditions: - lastTransitionTime: 2019-02-27T22:46:58Z status: "False" type: Failing - lastTransitionTime: 2019-02-27T22:50:12Z status: "False" type: Progressing - lastTransitionTime: 2019-02-27T22:50:12Z status: "True" type: Available - lastTransitionTime: 2019-02-27T22:46:57Z status: "True" type: Upgradeable extension: null relatedObjects: - group: operator.openshift.io name: cluster resource: consoles - group: config.openshift.io name: cluster resource: consoles - group: oauth.openshift.io name: console resource: oauthclients - group: "" name: openshift-console-operator resource: namespaces - group: "" name: openshift-console resource: namespaces versions: null Manually retrieve the console URL by executing the following command: USD oc --kubeconfig=USD{INSTALL_DIR}/auth/kubeconfig get route console -n openshift-console \ -o=jsonpath='{.spec.host}' console-openshift-console.apps.adahiya-1.devcluster.openshift.com 5.7. Troubleshooting a failure to add the ingress certificate to kubeconfig The installation program adds the default ingress certificate to the list of trusted client certificate authorities in USD{INSTALL_DIR}/auth/kubeconfig . If the installation program fails to add the ingress certificate to the kubeconfig file, you can retrieve the certificate from the cluster and add it. Procedure Retrieve the certificate from the cluster using the following command: USD oc --kubeconfig=USD{INSTALL_DIR}/auth/kubeconfig get configmaps default-ingress-cert \ -n openshift-config-managed -o=jsonpath='{.data.ca-bundle\.crt}' -----BEGIN CERTIFICATE----- MIIC/TCCAeWgAwIBAgIBATANBgkqhkiG9w0BAQsFADAuMSwwKgYDVQQDDCNjbHVz dGVyLWluZ3Jlc3Mtb3BlcmF0b3JAMTU1MTMwNzU4OTAeFw0xOTAyMjcyMjQ2Mjha Fw0yMTAyMjYyMjQ2MjlaMC4xLDAqBgNVBAMMI2NsdXN0ZXItaW5ncmVzcy1vcGVy YXRvckAxNTUxMzA3NTg5MIIBIjANBgkqhkiG9w0BAQEFAAOCAQ8AMIIBCgKCAQEA uCA4fQ+2YXoXSUL4h/mcvJfrgpBfKBW5hfB8NcgXeCYiQPnCKblH1sEQnI3VC5Pk 2OfNCF3PUlfm4i8CHC95a7nCkRjmJNg1gVrWCvS/ohLgnO0BvszSiRLxIpuo3C4S EVqqvxValHcbdAXWgZLQoYZXV7RMz8yZjl5CfhDaaItyBFj3GtIJkXgUwp/5sUfI LDXW8MM6AXfuG+kweLdLCMm3g8WLLfLBLvVBKB+4IhIH7ll0buOz04RKhnYN+Ebw tcvFi55vwuUCWMnGhWHGEQ8sWm/wLnNlOwsUz7S1/sW8nj87GFHzgkaVM9EOnoNI gKhMBK9ItNzjrP6dgiKBCQIDAQABoyYwJDAOBgNVHQ8BAf8EBAMCAqQwEgYDVR0T AQH/BAgwBgEB/wIBADANBgkqhkiG9w0BAQsFAAOCAQEAq+vi0sFKudaZ9aUQMMha CeWx9CZvZBblnAWT/61UdpZKpFi4eJ2d33lGcfKwHOi2NP/iSKQBebfG0iNLVVPz vwLbSG1i9R9GLdAbnHpPT9UG6fLaDIoKpnKiBfGENfxeiq5vTln2bAgivxrVlyiq +MdDXFAWb6V4u2xh6RChI7akNsS3oU9PZ9YOs5e8vJp2YAEphht05X0swA+X8V8T C278FFifpo0h3Q0Dbv8Rfn4UpBEtN4KkLeS+JeT+0o2XOsFZp7Uhr9yFIodRsnNo H/Uwmab28ocNrGNiEVaVH6eTTQeeZuOdoQzUbClElpVmkrNGY0M42K0PvOQ/e7+y AQ== -----END CERTIFICATE----- Add the certificate to the client-certificate-authority-data field in the USD{INSTALL_DIR}/auth/kubeconfig file. 5.8. Troubleshooting SSH access to cluster nodes For added security, you cannot SSH into the cluster from outside the cluster by default. However, you can access control plane and worker nodes from the provisioner node. If you cannot SSH into the cluster nodes from the provisioner node, the nodes might be waiting on the bootstrap VM. The control plane nodes retrieve their boot configuration from the bootstrap VM, and they cannot boot successfully if they do not retrieve the boot configuration. Procedure If you have physical access to the nodes, check their console output to determine if they have successfully booted. If the nodes are still retrieving their boot configuration, there might be problems with the bootstrap VM . Ensure you have configured the sshKey: '<ssh_pub_key>' setting in the install-config.yaml file, where <ssh_pub_key> is the public key of the kni user on the provisioner node. 5.9. Cluster nodes will not PXE boot When OpenShift Container Platform cluster nodes will not PXE boot, execute the following checks on the cluster nodes that will not PXE boot. This procedure does not apply when installing an OpenShift Container Platform cluster without the provisioning network. Procedure Check the network connectivity to the provisioning network. Ensure PXE is enabled on the NIC for the provisioning network and PXE is disabled for all other NICs. Verify that the install-config.yaml configuration file includes the rootDeviceHints parameter and boot MAC address for the NIC connected to the provisioning network. For example: control plane node settings Worker node settings 5.10. Installing creates no worker nodes The installation program does not provision worker nodes directly. Instead, the Machine API Operator scales nodes up and down on supported platforms. If worker nodes are not created after 15 to 20 minutes, depending on the speed of the cluster's internet connection, investigate the Machine API Operator. Procedure Check the Machine API Operator by running the following command: USD oc --kubeconfig=USD{INSTALL_DIR}/auth/kubeconfig \ --namespace=openshift-machine-api get deployments If USD{INSTALL_DIR} is not set in your environment, replace the value with the name of the installation directory. Example output NAME READY UP-TO-DATE AVAILABLE AGE cluster-autoscaler-operator 1/1 1 1 86m cluster-baremetal-operator 1/1 1 1 86m machine-api-controllers 1/1 1 1 85m machine-api-operator 1/1 1 1 86m Check the machine controller logs by running the following command: USD oc --kubeconfig=USD{INSTALL_DIR}/auth/kubeconfig \ --namespace=openshift-machine-api logs deployments/machine-api-controllers \ --container=machine-controller 5.11. Troubleshooting the Cluster Network Operator The Cluster Network Operator is responsible for deploying the networking components. It runs early in the installation process, after the control plane nodes have come up but before the installation program removes the bootstrap control plane. Issues with this Operator might indicate installation program issues. Procedure Ensure the network configuration exists by running the following command: USD oc get network -o yaml cluster If it does not exist, the installation program did not create it. To find out why, run the following command: USD openshift-install create manifests Review the manifests to determine why the installation program did not create the network configuration. Ensure the network is running by entering the following command: USD oc get po -n openshift-network-operator 5.12. Unable to discover new bare metal hosts using the BMC In some cases, the installation program will not be able to discover the new bare metal hosts and issue an error, because it cannot mount the remote virtual media share. For example: ProvisioningError 51s metal3-baremetal-controller Image provisioning failed: Deploy step deploy.deploy failed with BadRequestError: HTTP POST https://<bmc_address>/redfish/v1/Managers/iDRAC.Embedded.1/VirtualMedia/CD/Actions/VirtualMedia.InsertMedia returned code 400. Base.1.8.GeneralError: A general error has occurred. See ExtendedInfo for more information Extended information: [ { "Message": "Unable to mount remote share https://<ironic_address>/redfish/boot-<uuid>.iso.", "MessageArgs": [ "https://<ironic_address>/redfish/boot-<uuid>.iso" ], "MessageArgs@odata.count": 1, "MessageId": "IDRAC.2.5.RAC0720", "RelatedProperties": [ "#/Image" ], "RelatedProperties@odata.count": 1, "Resolution": "Retry the operation.", "Severity": "Informational" } ]. In this situation, if you are using virtual media with an unknown certificate authority, you can configure your baseboard management controller (BMC) remote file share settings to trust an unknown certificate authority to avoid this error. Note This resolution was tested on OpenShift Container Platform 4.11 with Dell iDRAC 9 and firmware version 5.10.50. 5.13. Troubleshooting worker nodes that cannot join the cluster Installer-provisioned clusters deploy with a DNS server that includes a DNS entry for the api-int.<cluster_name>.<base_domain> URL. If the nodes within the cluster use an external or upstream DNS server to resolve the api-int.<cluster_name>.<base_domain> URL and there is no such entry, worker nodes might fail to join the cluster. Ensure that all nodes in the cluster can resolve the domain name. Procedure Add a DNS A/AAAA or CNAME record to internally identify the API load balancer. For example, when using dnsmasq, modify the dnsmasq.conf configuration file: USD sudo nano /etc/dnsmasq.conf address=/api-int.<cluster_name>.<base_domain>/<IP_address> address=/api-int.mycluster.example.com/192.168.1.10 address=/api-int.mycluster.example.com/2001:0db8:85a3:0000:0000:8a2e:0370:7334 Add a DNS PTR record to internally identify the API load balancer. For example, when using dnsmasq, modify the dnsmasq.conf configuration file: USD sudo nano /etc/dnsmasq.conf ptr-record=<IP_address>.in-addr.arpa,api-int.<cluster_name>.<base_domain> ptr-record=10.1.168.192.in-addr.arpa,api-int.mycluster.example.com Restart the DNS server. For example, when using dnsmasq, execute the following command: USD sudo systemctl restart dnsmasq These records must be resolvable from all the nodes within the cluster. 5.14. Cleaning up installations In case of an earlier failed deployment, remove the artifacts from the failed attempt before trying to deploy OpenShift Container Platform again. Procedure Power off all bare-metal nodes before installing the OpenShift Container Platform cluster by using the following command: USD ipmitool -I lanplus -U <user> -P <password> -H <management_server_ip> power off Remove all old bootstrap resources if any remain from an earlier deployment attempt by using the following script: for i in USD(sudo virsh list | tail -n +3 | grep bootstrap | awk {'print USD2'}); do sudo virsh destroy USDi; sudo virsh undefine USDi; sudo virsh vol-delete USDi --pool USDi; sudo virsh vol-delete USDi.ign --pool USDi; sudo virsh pool-destroy USDi; sudo virsh pool-undefine USDi; done Delete the artifacts that the earlier installation generated by using the following command: USD cd ; /bin/rm -rf auth/ bootstrap.ign master.ign worker.ign metadata.json \ .openshift_install.log .openshift_install_state.json Re-create the OpenShift Container Platform manifests by using the following command: USD ./openshift-baremetal-install --dir ~/clusterconfigs create manifests 5.15. Issues with creating the registry When creating a disconnected registry, you might encounter a "User Not Authorized" error when attempting to mirror the registry. This error might occur if you fail to append the new authentication to the existing pull-secret.txt file. Procedure Check to ensure authentication is successful: USD /usr/local/bin/oc adm release mirror \ -a pull-secret-update.json --from=USDUPSTREAM_REPO \ --to-release-image=USDLOCAL_REG/USDLOCAL_REPO:USD{VERSION} \ --to=USDLOCAL_REG/USDLOCAL_REPO Note Example output of the variables used to mirror the install images: UPSTREAM_REPO=USD{RELEASE_IMAGE} LOCAL_REG=<registry_FQDN>:<registry_port> LOCAL_REPO='ocp4/openshift4' The values of RELEASE_IMAGE and VERSION were set during the Retrieving OpenShift Installer step of the Setting up the environment for an OpenShift installation section. After mirroring the registry, confirm that you can access it in your disconnected environment: USD curl -k -u <user>:<password> https://registry.example.com:<registry_port>/v2/_catalog {"repositories":["<Repo_Name>"]} 5.16. Miscellaneous issues 5.16.1. Addressing the runtime network not ready error After the deployment of a cluster you might receive the following error: The Cluster Network Operator is responsible for deploying the networking components in response to a special object created by the installation program. It runs very early in the installation process, after the control plane (master) nodes have come up, but before the bootstrap control plane has been torn down. It can be indicative of more subtle installation program issues, such as long delays in bringing up control plane (master) nodes or issues with apiserver communication. Procedure Inspect the pods in the openshift-network-operator namespace: USD oc get all -n openshift-network-operator NAME READY STATUS RESTARTS AGE pod/network-operator-69dfd7b577-bg89v 0/1 ContainerCreating 0 149m On the provisioner node, determine that the network configuration exists: USD kubectl get network.config.openshift.io cluster -oyaml apiVersion: config.openshift.io/v1 kind: Network metadata: name: cluster spec: serviceNetwork: - 172.30.0.0/16 clusterNetwork: - cidr: 10.128.0.0/14 hostPrefix: 23 networkType: OVNKubernetes If it does not exist, the installation program did not create it. To determine why the installation program did not create it, execute the following: USD openshift-install create manifests Check that the network-operator is running: USD kubectl -n openshift-network-operator get pods Retrieve the logs: USD kubectl -n openshift-network-operator logs -l "name=network-operator" On high availability clusters with three or more control plane nodes, the Operator will perform leader election and all other Operators will sleep. For additional details, see Troubleshooting . 5.16.2. Addressing the "No disk found with matching rootDeviceHints" error message After you deploy a cluster, you might receive the following error message: No disk found with matching rootDeviceHints To address the No disk found with matching rootDeviceHints error message, a temporary workaround is to change the rootDeviceHints to minSizeGigabytes: 300 . After you change the rootDeviceHints settings, boot the CoreOS and then verify the disk information by using the following command: USD udevadm info /dev/sda If you are using DL360 Gen 10 servers, be aware that they have an SD-card slot that might be assigned the /dev/sda device name. If no SD card is present in the server, it can cause conflicts. Ensure that the SD card slot is disabled in the server's BIOS settings. If the minSizeGigabytes workaround is not fulfilling the requirements, you might need to revert rootDeviceHints back to /dev/sda . This change allows ironic images to boot successfully. An alternative approach to fixing this problem is by using the serial ID of the disk. However, be aware that finding the serial ID can be challenging and might make the configuration file less readable. If you choose this path, ensure that you gather the serial ID using the previously documented command and incorporate it into your configuration. 5.16.3. Cluster nodes not getting the correct IPv6 address over DHCP If the cluster nodes are not getting the correct IPv6 address over DHCP, check the following: Ensure the reserved IPv6 addresses reside outside the DHCP range. In the IP address reservation on the DHCP server, ensure the reservation specifies the correct DHCP Unique Identifier (DUID). For example: # This is a dnsmasq dhcp reservation, 'id:00:03:00:01' is the client id and '18:db:f2:8c:d5:9f' is the MAC Address for the NIC id:00:03:00:01:18:db:f2:8c:d5:9f,openshift-master-1,[2620:52:0:1302::6] Ensure that route announcements are working. Ensure that the DHCP server is listening on the required interfaces serving the IP address ranges. 5.16.4. Cluster nodes not getting the correct hostname over DHCP During IPv6 deployment, cluster nodes must get their hostname over DHCP. Sometimes the NetworkManager does not assign the hostname immediately. A control plane (master) node might report an error such as: This error indicates that the cluster node likely booted without first receiving a hostname from the DHCP server, which causes kubelet to boot with a localhost.localdomain hostname. To address the error, force the node to renew the hostname. Procedure Retrieve the hostname : [core@master-X ~]USD hostname If the hostname is localhost , proceed with the following steps. Note Where X is the control plane node number. Force the cluster node to renew the DHCP lease: [core@master-X ~]USD sudo nmcli con up "<bare_metal_nic>" Replace <bare_metal_nic> with the wired connection corresponding to the baremetal network. Check hostname again: [core@master-X ~]USD hostname If the hostname is still localhost.localdomain , restart NetworkManager : [core@master-X ~]USD sudo systemctl restart NetworkManager If the hostname is still localhost.localdomain , wait a few minutes and check again. If the hostname remains localhost.localdomain , repeat the steps. Restart the nodeip-configuration service: [core@master-X ~]USD sudo systemctl restart nodeip-configuration.service This service will reconfigure the kubelet service with the correct hostname references. Reload the unit files definition since the kubelet changed in the step: [core@master-X ~]USD sudo systemctl daemon-reload Restart the kubelet service: [core@master-X ~]USD sudo systemctl restart kubelet.service Ensure kubelet booted with the correct hostname: [core@master-X ~]USD sudo journalctl -fu kubelet.service If the cluster node is not getting the correct hostname over DHCP after the cluster is up and running, such as during a reboot, the cluster will have a pending csr . Do not approve a csr , or other issues might arise. Addressing a csr Get CSRs on the cluster: USD oc get csr Verify if a pending csr contains Subject Name: localhost.localdomain : USD oc get csr <pending_csr> -o jsonpath='{.spec.request}' | base64 --decode | openssl req -noout -text Remove any csr that contains Subject Name: localhost.localdomain : USD oc delete csr <wrong_csr> 5.16.5. Routes do not reach endpoints During the installation process, it is possible to encounter a Virtual Router Redundancy Protocol (VRRP) conflict. This conflict might occur if a previously used OpenShift Container Platform node that was once part of a cluster deployment using a specific cluster name is still running but not part of the current OpenShift Container Platform cluster deployment using that same cluster name. For example, a cluster was deployed using the cluster name openshift , deploying three control plane (master) nodes and three worker nodes. Later, a separate install uses the same cluster name openshift , but this redeployment only installed three control plane (master) nodes, leaving the three worker nodes from a deployment in an ON state. This might cause a Virtual Router Identifier (VRID) conflict and a VRRP conflict. Get the route: USD oc get route oauth-openshift Check the service endpoint: USD oc get svc oauth-openshift NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE oauth-openshift ClusterIP 172.30.19.162 <none> 443/TCP 59m Attempt to reach the service from a control plane (master) node: [core@master0 ~]USD curl -k https://172.30.19.162 { "kind": "Status", "apiVersion": "v1", "metadata": { }, "status": "Failure", "message": "forbidden: User \"system:anonymous\" cannot get path \"/\"", "reason": "Forbidden", "details": { }, "code": 403 Identify the authentication-operator errors from the provisioner node: USD oc logs deployment/authentication-operator -n openshift-authentication-operator Event(v1.ObjectReference{Kind:"Deployment", Namespace:"openshift-authentication-operator", Name:"authentication-operator", UID:"225c5bd5-b368-439b-9155-5fd3c0459d98", APIVersion:"apps/v1", ResourceVersion:"", FieldPath:""}): type: 'Normal' reason: 'OperatorStatusChanged' Status for clusteroperator/authentication changed: Degraded message changed from "IngressStateEndpointsDegraded: All 2 endpoints for oauth-server are reporting" Solution Ensure that the cluster name for every deployment is unique, ensuring no conflict. Turn off all the rogue nodes which are not part of the cluster deployment that are using the same cluster name. Otherwise, the authentication pod of the OpenShift Container Platform cluster might never start successfully. 5.16.6. Failed Ignition during Firstboot During the Firstboot, the Ignition configuration may fail. Procedure Connect to the node where the Ignition configuration failed: Failed Units: 1 machine-config-daemon-firstboot.service Restart the machine-config-daemon-firstboot service: [core@worker-X ~]USD sudo systemctl restart machine-config-daemon-firstboot.service 5.16.7. NTP out of sync The deployment of OpenShift Container Platform clusters depends on NTP synchronized clocks among the cluster nodes. Without synchronized clocks, the deployment may fail due to clock drift if the time difference is greater than two seconds. Procedure Check for differences in the AGE of the cluster nodes. For example: USD oc get nodes NAME STATUS ROLES AGE VERSION master-0.cloud.example.com Ready master 145m v1.29.4 master-1.cloud.example.com Ready master 135m v1.29.4 master-2.cloud.example.com Ready master 145m v1.29.4 worker-2.cloud.example.com Ready worker 100m v1.29.4 Check for inconsistent timing delays due to clock drift. For example: USD oc get bmh -n openshift-machine-api master-1 error registering master-1 ipmi://<out_of_band_ip> USD sudo timedatectl Local time: Tue 2020-03-10 18:20:02 UTC Universal time: Tue 2020-03-10 18:20:02 UTC RTC time: Tue 2020-03-10 18:36:53 Time zone: UTC (UTC, +0000) System clock synchronized: no NTP service: active RTC in local TZ: no Addressing clock drift in existing clusters Create a Butane config file including the contents of the chrony.conf file to be delivered to the nodes. In the following example, create 99-master-chrony.bu to add the file to the control plane nodes. You can modify the file for worker nodes or repeat this procedure for the worker role. Note See "Creating machine configs with Butane" for information about Butane. variant: openshift version: 4.16.0 metadata: name: 99-master-chrony labels: machineconfiguration.openshift.io/role: master storage: files: - path: /etc/chrony.conf mode: 0644 overwrite: true contents: inline: | server <NTP_server> iburst 1 stratumweight 0 driftfile /var/lib/chrony/drift rtcsync makestep 10 3 bindcmdaddress 127.0.0.1 bindcmdaddress ::1 keyfile /etc/chrony.keys commandkey 1 generatecommandkey noclientlog logchange 0.5 logdir /var/log/chrony 1 Replace <NTP_server> with the IP address of the NTP server. Use Butane to generate a MachineConfig object file, 99-master-chrony.yaml , containing the configuration to be delivered to the nodes: USD butane 99-master-chrony.bu -o 99-master-chrony.yaml Apply the MachineConfig object file: USD oc apply -f 99-master-chrony.yaml Ensure the System clock synchronized value is yes : USD sudo timedatectl Local time: Tue 2020-03-10 19:10:02 UTC Universal time: Tue 2020-03-10 19:10:02 UTC RTC time: Tue 2020-03-10 19:36:53 Time zone: UTC (UTC, +0000) System clock synchronized: yes NTP service: active RTC in local TZ: no To setup clock synchronization prior to deployment, generate the manifest files and add this file to the openshift directory. For example: USD cp chrony-masters.yaml ~/clusterconfigs/openshift/99_masters-chrony-configuration.yaml Then, continue to create the cluster. 5.17. Reviewing the installation After installation, ensure the installation program deployed the nodes and pods successfully. Procedure When the OpenShift Container Platform cluster nodes are installed appropriately, the following Ready state is seen within the STATUS column: USD oc get nodes NAME STATUS ROLES AGE VERSION master-0.example.com Ready master,worker 4h v1.29.4 master-1.example.com Ready master,worker 4h v1.29.4 master-2.example.com Ready master,worker 4h v1.29.4 Confirm the installation program deployed all pods successfully. The following command removes any pods that are still running or have completed as part of the output. USD oc get pods --all-namespaces | grep -iv running | grep -iv complete
