Hi All,
I was able to login to the instance. I see that kubelet service is in
activating state. When I checked the journalctl, found the below.
*Oct 19 05:18:34 kubernetes-cluster-6cdrblcpckny-master-0 systemd[1]:
Started Kubelet via Hyperkube (System Container).Oct 19 05:18:34
kubernetes-cluster-6cdrblcpckny-master-0 bash[6521]: Error: statfs

kubernetes-cluster-6cdrblcpckny-master-0 systemd[1]: Stopped Kubelet via
Hyperkube (System Container).*
Executed the below command to fix this issue.
*mkdir -p /sys/fs/cgroup/systemd*
Now I am getiing the below error. Has anybody seen this issue.
*failed to get the kubelet's cgroup: mountpoint for cpu not found. Kubelet
system container metrics may be missing.failed to get the container
runtime's cgroup: failed to get container name for docker process:
mountpoint for cpu not found. failed to run Kubelet: mountpoint for not
