Quobyte driver

The Quobyte volume driver enables storing Block Storage service volumes on a Quobyte storage back end. Block Storage service back ends are mapped to Quobyte volumes and individual Block Storage service volumes are stored as files on a Quobyte volume. Selection of the appropriate Quobyte volume is done by the aforementioned back end configuration that specifies the Quobyte volume explicitly.

Note

Note the dual use of the term volume in the context of Block Storage service volumes and in the context of Quobyte volumes.

For more information see the Quobyte support webpage.

Supported operations

The Quobyte volume driver supports the following volume operations:

  • Create, delete, attach, and detach volumes
  • Secure NAS operation (Starting with Mitaka release secure NAS operation is optional but still default)
  • Create and delete a snapshot
  • Create a volume from a snapshot
  • Extend a volume
  • Clone a volume
  • Copy a volume to image
  • Generic volume migration (no back end optimization)

Note

When running VM instances off Quobyte volumes, ensure that the Quobyte Compute service driver has been configured in your OpenStack cloud.

Configuration

To activate the Quobyte volume driver, configure the corresponding volume_driver parameter:

volume_driver = cinder.volume.drivers.quobyte.QuobyteDriver

The following table contains the configuration options supported by the Quobyte driver:
