Multus-CNI error on CP4I OpenShift cluster

  • 1.  Multus-CNI error on CP4I OpenShift cluster

    Posted Fri September 09, 2022 09:23 PM
    Hi,
    We have CP4I v2022 installed on Openshift v4.10, it was working fine till friday (09/09) and suddenly started getting error as below:

     

    "on oshiftqa-bbqx2-worker-eastus22-tqcbf112 times in the last 2 hours(combined from similar events): Failed to create pod sandbox: rpc error: code = Unknown desc = failed to create pod network sandbox k8s_ac12d01-dash-6fd769ddf6-fzf7t_dev_d1eadbc9-a03b-46b4-b326-2a4bb9d1d0cb_0(be6e8e5d79e24e46a22386ac756910edd847911193df804f925938f9bd086c48): error adding pod dev_ac12d01-dash-6fd769ddf6-fzf7t to CNI network "multus-cni-network": plugin type="multus" name="multus-cni-network" failed (add): Multus: [dev/ac12d01-dash-6fd769ddf6-fzf7t/d1eadbc9-a03b-46b4-b326-2a4bb9d1d0cb]: error getting pod: Get https://[api-int.oshiftqa.cloudpak-qa.borgwarner.net]:6443/api/v1/namespaces/dev/pods/ac12d01-dash-6fd769ddf6-fzf7t?timeout=1m0s: dial tcp: i/o timeout"

     Due to this error none of the pods are getting created (always in container creating state) or deleted (always in Terminating state). How to troubleshoot this issue and what is the solution to resolve it?
