# Limitations

Below is a list of parameters that can only be configured during bootstrap time.

Immutable Parameters

These storage-related parameters cannot be changed after initial deployment. Repeat: using parameters to resize disk, change storage class, or switch between persistent/ephemeral storage is not supported.

Changing the above parameters will trigger a not-allowed plan. Which basically skips updating any resources. This is to avoid any update done by mistake or human error.

# Resizing the PVC

Resizing the disk depends on the storage class of your Kubernetes cluster. To resize the disk being used by a broker, users can edit the pvc and expand the disk. You can read more about it in resizing the PVC post.
