# Unable To Add Node Due To "Device or resource busy"

## Problem

Unable to add a new worker node with partition `/var/lib/kubelet` . Log shows "rm: cannot remove '/var/lib/kubelet': Device or resource busy"

Environment

* Platform9 Managed Kubernetes - All Versions

## Answer

* Adding a worker node with the partition `/var/lib/kubelet` already mounted on it and see the "Device or resource busy" log. This is expected as the kubelet data directory i.e `/var/lib/kubelet` is cleaned up to ensure no pod state are stored outside the etcd database, for consistency. This operation fails if the directory is already mounted.
* To resolve this issue, unmount the`/var/lib/kubelet` filesystem from the nodes and let pf9 installer take care of creating this path during the node onboarding.
