If the automatically provisioned node pools that OneFS creates are not appropriate for an environment, they can be manually reconfigured. This reconfiguration is done by creating a manual node pool and moving nodes from an existing node pool to the newly created one.
Note: The recommendation is to use the default, automatically provisioned node pools. Manually assigned pools may not provide the same performance and storage efficiency levels as automatically assigned pools. In particular, if your changes result in fewer than 20 nodes in the manual node pool.
