[discostur]

Hi,

i'm running cephfs via ceph-csi and on some nodes i get the following errror in the ceph-csi-cephfs-nodeplugin container:

Failed to create bus connection: Host is down
, failed with: exit status 1

I get this error on some nodes - on others not. Not sure what the error is related to or if it has any impact on provisioning volumes.

So my question is if the error is OK or if anything is going wrong here?

Thanks

@discostur this should not be a problem, it's coming from the kubernetes package we use for mount operation. this is just an info log.

@Madhu-1 ok thanks - will close this ;)

kubernetes/kubernetes#111083 has been proposed as a change to the k8s.io/mount-utils package. It will address the scary logging for NodeGetVolumeStats procedure calls.
