= About FlexVolume drivers

[role="_abstract"]
When working with FlexVolume drivers, it is helpful to understand how {product-title} interact with the drivers.

A FlexVolume driver is an executable file that resides in a well-defined directory on all nodes in the cluster. {product-title} calls the FlexVolume driver whenever it needs to mount or unmount a volume represented by a `PersistentVolume` object with `flexVolume` as the source.

[IMPORTANT]
====
Attach and detach operations are not supported in {product-title} for FlexVolume.
