AL2023 AMI: "invalid capacity 0 on image filesystem" kubelet warning

[markusmiliats]

I'm not sure if this is a bug so I'm filing this as a general question.
During node startup I can see the event "invalid capacity 0 on image filesystem" as a warning from kubelet.
Using journalctl -u kubelet I can see additional information for this warning:
kubelet.go:1440] "Image garbage collection failed once. Stats initialization may not have completed yet" err="invalid capacity 0 on image filesystem"
Afterwards, the node starts normally, pods are assigned to the node and I cannot observe any abnormal behaviour.
I'm wondering if anyone else encountered this and if I can safely ignore this warning? (because Stats initialization may not have completed yet as the message already suggests 😄)

You can ignore it.
