The cinder.volume.drivers.storpool Module¶

StorPool block device driver

class StorPoolDriver(*args, **kwargs)¶

Bases: cinder.volume.driver.VolumeDriver

The StorPool block device driver.

Version history:

0.1.0   - Initial driver
0.2.0   - Bring the driver up to date with Kilo and Liberty:
          - implement volume retyping and migrations
          - use the driver.*VD ABC metaclasses
          - bugfix: fall back to the configured StorPool template
1.0.0   - Imported into OpenStack Liberty with minor fixes
1.1.0   - Bring the driver up to date with Liberty and Mitaka:
          - drop the CloneableVD and RetypeVD base classes
          - enable faster volume copying by specifying
            sparse_volume_copy=true in the stats report
1.1.1   - Fix the internal _storpool_client_id() method to
          not break on an unknown host name or UUID; thus,
          remove the StorPoolConfigurationMissing exception.
1.1.2   - Bring the driver up to date with Pike: do not
          translate the error messages
1.2.0   - Inherit from VolumeDriver, implement get_pool()
1.2.1   - Implement interface.volumedriver, add CI_WIKI_NAME,
          fix the docstring formatting
1.2.2   - Reintroduce the driver into OpenStack Queens,
          add ignore_errors to the internal _detach_volume() method
