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

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.
