I’m running a Rancher launched cluster on Centos7.7 with Docker 1.13.1. After updating from Rancher 2.2.5 (Kubernetes 1.11.6) to 2.3.5 (Kubernetes 1.17.2), I’m seeing a lot of the warning in kubelet logs like this…
`W0210 22:55:29.835850 12833 volume_linux.go:45] Setting volume ownership for /var/lib/kubelet/pods/8bfcd32c-bea6-418e-a9cd-a80aae662aab/volumes/kubernetes.io~secret/exporter-kube-state-cluster-monitoring-token-624mh and fsGroup set. If the volume has a lot of files then setting volume ownership could be slow, see https://github.com/kubernetes/kubernetes/issues/69699`
These log entries are spammed at roughly 70 second intervals indefinitely. They’re logged for every configmap or secret volume mounted in pods where
fsGroup is set.
Has anyone else experienced this? Any help would be appreciated.
