Hello Suresh,

In one of the case, I got the same error while restoring the ETCD backup.

~~~
tar: *restore-etcd-pod/pod.yaml: Not found in archive
tar: Exiting with failure status due to previous errors
~~~

After that the ETCD is completely down and due to that we can't even follow the below workaround.

~~~
$ oc debug node/master-0.example.com
sh-4.2# chroot /host
sh-4.4# touch $(crictl inspect $(crictl ps --name etcd$ -q) | jq -r '.status.mounts | .[] | select (.containerPath=="/etc/kubernetes/static-pod-resources") | .hostPath')
~~~

Is there any method or steps to fix this now? Will it work if we manually untar the backup and create the missing file with proper contents?

Regards,
Ayush Garg
