Considerations for Using Node Volume Mounts

You can provision a TKG Service cluster with one or more node volume mounts. Before you do, keep in mind important considerations.

Node Volume Mount Considerations

The table summarizes node volume mount points for TKG Service clusters. Refer to the following KB article for complete details on node volume mount limitations: https://kb.vmware.com/s/article/92153.

See also the following topic for information on changing a volume mount after a cluster has been provisioned: Manually Scale a Cluster Using Kubectl.

Volume Mount	Node	Support	Desc
/var/lib/containerd	Worker	Full	Increases the size available for container image caching.
/var/lib/kubelet	Worker	Full	Increases the size available for ephemeral container storage.
/var/lib/etcd	Control plane	None	Does not increase the size of etcd because etcd has a 2GB hard limit. Can also prevent cluster creation due to PVC timeouts.
/ (root) /var /var/lib /etc	Control Plane Worker	None	Any directory that is being used by core system processes are not supported, including those listed and any others (list is not exhaustive).
