dockerd mount error on cadvisor image

[ggpaue]

Hi, we are currently using cadvisro v0.31.0 and facing the current issue when installing cadvisor on worker node.

OCI runtime create failed: container_linux.go:348: starting container process caused "process_linux.go:402: container init caused "rootfs_linux.go:58: mounting
\"/var/vcap/sys/run/docker/docker.sock\" to rootfs \"/var/vcap/store/docker/docker/overlay2/xxxxxx/merged\"
at \"/var/vcap/store/docker/docker/overlay2/xxxxxx/merged/run/docker.sock\" caused \"not a directory\""": unknown: Are you trying to mount a directory onto a file (or vice-versa)? Check if the specified host path exists and is the expected type

This is only happens on part of the worker nodes and we are not sure if this is a problem from cadvisor image or dockerd, please advise if you have any idea
Thank you very much!

That error looks like it is coming from docker. It looks like your mount has a typo?

Thanks for the reply, can you point out where the typo?
This is wired because we apply the same install logic to all workers but only part of the workers have this error, and only the pod install cadvisor has this error.
We have checked dockerd is running properly, is there any other way to dive deeper?
Also, would upgrade cadvisor from v0.31.0 to a newer version will help?
Thank you David!

Actually, I think i misread the initial error. Can you paste the command you are using to run this?
