Openshift nodes are NotReady

Posted on

Hi,

We are running with OCP v4.6 and IBM CPD version 3.5.

ETCD certificates got expired, so we have manually re-generated the certificates and applied on environments.

But after this our Master and Worker nodes are not coming as Ready status and also oc commands are not working.

[root@master0 ~]# oc get nodes
NAME STATUS ROLES AGE VERSION
master0.cpd-test.*** NotReady master,worker 3y47d v1.19.0+3b01205
master1.cpd-test.*** NotReady master,worker 3y47d v1.19.0+3b01205
master2.cpd-test.*** NotReady master,worker 3y47d v1.19.0+3b01205
worker0.cpd-test.*** NotReady worker 3y47d v1.19.0+3b01205
worker1.cpd-test.*** NotReady worker 3y47d v1.19.0+3b01205
worker2.cpd-test.*** NotReady worker 3y47d v1.19.0+3b01205
[root@master0 ~]#

Any suggestions to recover these nodes. Thanks in advance.
