Volume mode is the PersistentVolumeClaim spec field that requests storage as either a filesystem or a raw block device. Filesystem is the default. section 10.2.1
Choose the mode according to how the application consumes storage:
- Filesystem mounts the PersistentVolume at a directory in the container’s file tree. section 10.2.1
- Block exposes the volume as a raw block device without a filesystem, allowing applications to handle data directly. section 10.2.1
- Block mode is typically used by specialized applications such as database systems. section 10.2.1
Default filesystem request
A quiz-data PersistentVolumeClaim that omits volumeMode requests a filesystem volume automatically. Add volumeMode: Block when the application requires an unformatted raw device. section 10.2.1
