kubernetes: GracefulNodeShutdown not work

What happened?

For 1.21, by checking https://kubernetes.io/blog/2021/04/21/graceful-node-shutdown-beta/, I added below args to kubelet-config.json:

  "shutdownGracePeriod": "1m30s",
  "shutdownGracePeriodCriticalPods": "30s"

I can see 99-kubelet.conf:

ubuntu@ip-10-120-80-6:~$ uname -a
Linux ip-10-120-80-6 5.11.0-1022-aws #23~20.04.1-Ubuntu SMP Mon Nov 15 14:03:19 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux

ubuntu@ip-10-120-80-6:~$ cat /etc/systemd/logind.conf.d/99-kubelet.conf
# Kubelet logind override
[Login]
InhibitDelayMaxSec=90

But I can’t see inhibitor from kubelet:

ubuntu@ip-10-120-80-6:~$ sudo systemd-inhibit --list
WHO                          UID USER PID COMM            WHAT     WHY                                                       MODE
Unattended Upgrades Shutdown 0   root 588 unattended-upgr shutdown Stop ongoing upgrades or perform upgrades before shutdown delay

1 inhibitors listed.

What did you expect to happen?

I should be able to see inhibitors from kubelet like this?

kubelet-node ~ # systemd-inhibit --list
    Who: kubelet (UID 0/root, PID 1515/kubelet)
    What: shutdown
    Why: Kubelet needs time to handle node shutdown
    Mode: delay

1 inhibitors listed.

How can we reproduce it (as minimally and precisely as possible)?

start a new k8s node running 1.21 and run sudo systemd-inhibit --list

Anything else we need to know?
