Permission denied on hugetlb due to wrong filename #77169
Description
What happened:
When running kubeadm init --pod-network-cidr=10.244.0.0/16 on OpenSUSE Kubic for aarch64 (board with amlogic s905w) kubelet spits out the following error and exits.
kubelet.go:1359] Failed to start ContainerManager failed to initialize top level QOS containers: failed to update top level Burstable QOS cgroup : failed to set supported cgroup subsystems for cgroup [kubepods burstable]: Failed to set config for supported subsystems : failed to write 4611686018427387904 to hugetlb.64kB.limit_in_bytes: open /sys/fs/cgroup/hugetlb/kubepods/burstable/hugetlb.64kB.limit_in_bytes: permission denied
What you expected to happen:
For kubelet to not error and exit.
How to reproduce it (as minimally and precisely as possible):
I don't know if this is the same for all ARM boards or just amlogic.
Anything else we need to know?:
/sys/fs/cgroup/hugetlb/kubepods/burstable/hugetlb.64KB.limit_in_bytes exists but not /sys/fs/cgroup/hugetlb/kubepods/burstable/hugetlb.64kB.limit_in_bytes (notice capitalization of KB).
Environment:
- Kubernetes version (use
kubectl version):v1.14.1 - Cloud provider or hardware configuration: Amlogic s905w board with 2GiB RAM.

cat /etc/os-release):
