Red Hat Bugzilla – Bug 1521087
'oc get nodes -o wide' returns Unknown in the OS-IMAGE field
Last modified: 2018-10-11 03:19:41 EDT
Description of problem: Post installation, 'oc get nodes -o wide' returns the following: [root@master1.x.y ~]# oc get nodes -o wide NAME STATUS AGE VERSION EXTERNAL-IP OS-IMAGE KERNEL-VERSION ..8< 3.10.0-693.5.2.el7.x86_64 master1.x.y Ready,SchedulingDisabled 9d v1.6.1+5115d708d7 <none> OpenShift Enterprise 3.10.0-693.5.2.el7.x86_64 node1.x.y Ready 9d v1.6.1+5115d708d7 <none> Unknown 3.10.0-693.5.2.el7.x86_64 ..8< So the 'good' host is returning OS-IMAGE as 'Openshift Enterprise' and the 'bad' node is returning Unknown. Looking at /etc/os-release, this is what is shown on the bad node: [root@node1.x.y ~]$ cat /etc/os-release NAME="Red Hat Enterprise Linux Server" VERSION="7.4 (Maipo)" ID="rhel" ID_LIKE="fedora" VARIANT="Server" VARIANT_ID="server" VERSION_ID="7.4" PRETTY_NAME=OpenShift ANSI_COLOR="0;31" CPE_NAME="cpe:/o:redhat:enterprise_linux:7.4:GA:server" HOME_URL="https://www.redhat.com/" BUG_REPORT_URL="https://bugzilla.redhat.com/" REDHAT_BUGZILLA_PRODUCT="Red Hat Enterprise Linux 7" REDHAT_BUGZILLA_PRODUCT_VERSION=7.4 REDHAT_SUPPORT_PRODUCT="Red Hat Enterprise Linux" REDHAT_SUPPORT_PRODUCT_VERSION="7.4" We notice on the 'good' node, the PRETTY_NAME='OpenShift Enterprise'. We have confirmed that openshift_deployment_type=openshift-enterprise is in the hosts file from the installation and the /etc/ansible/facts.d/openshift.fact on the nodes are all accurate/correct. As a test, we modified the PRETTY_NAME= on the 'bad' node to show PRETTY_NAME='OpenShift Enterprise'. This led 'oc get nodes -o wide' to report the correct OS-IMAGE. When the node is rebooted however, the os-release and OS-IMAGE reverts back to the previous configuration. Version-Release number of selected component (if applicable): atomic-openshift-3.6.173.0.21-1.git.0.f95b0e7.el7.x86_64 How reproducible: Have attemtped to reproduce this in-house, however we have not been able to reproduce this issue. Steps to Reproduce: 1.n/a 2. 3. Actual results: oc get nodes -o wide returns Unknown in the OS-IMAGE field Expected results: oc get nodes -o wide returns OpenShift Enterprise in the OS-IMAGE field Additional info:
@Michal wondering if you had seen this before / if it could be a node issue?
Honestly this looks like an installer problem. Moving to them, it's not related to CLI in any way.

Now the "bad" node shows exactly what in PRETTY_NAME [root@ip-172-18-6-174 ~]# cat /etc/os-release|grep PRETTY PRETTY_NAME="OpenShift" [root@ip-172-18-14-31 ~]# oc get nodes -o wide NAME STATUS ROLES AGE VERSION INTERNAL-IP EXTERNAL-IP OS-IMAGE KERNEL-VERSION CONTAINER-RUNTIME ip-172-18-10-88.ec2.internal Ready compute 1h v1.11.0+d4cacc0 172.18.10.88 34.207.213.202 Red Hat Enterprise Linux Server 7.5 (Maipo) 3.10.0-862.11.6.el7.x86_64 docker://1.13.1 ip-172-18-14-31.ec2.internal Ready master 2h v1.11.0+d4cacc0 172.18.14.31 54.89.133.133 Red Hat Enterprise Linux Server 7.5 (Maipo) 3.10.0-862.11.6.el7.x86_64 docker://1.13.1 ip-172-18-6-174.ec2.internal Ready <none> 1h v1.11.0+d4cacc0 172.18.6.174 34.207.103.156 OpenShift 3.10.0-862.11.6.el7.x86_64 docker://1.13.1 [root@ip-172-18-6-174 ~]# oc version oc v3.11.0-0.22.0 kubernetes v1.11.0+d4cacc0 features: Basic-Auth GSSAPI Kerberos SPNEGO [root@ip-172-18-14-31 ~]# cat /etc/redhat-release Red Hat Enterprise Linux Server release 7.5 (Maipo)
