The cinder.volume.drivers.scality Module

Scality SOFS Volume Driver.

class ScalityDriver(execute=<function execute at 0x2a496e0>, *args, **kwargs)

Bases: cinder.volume.driver.VolumeDriver

Scality SOFS cinder driver.

Creates sparse files on SOFS for hypervisors to use as block devices.

attach_volume(context, volume_id, instance_uuid, mountpoint)

Callback for volume attached to instance.

check_for_setup_error()

Returns an error if prerequisites aren’t met.

clone_image(volume, image_location)

Create a volume efficiently from an existing image.

image_location is a string whose format depends on the image service backend in use. The driver should use it to determine whether cloning is possible.

Returns a boolean indicating whether cloning occurred

copy_image_to_volume(context, volume, image_service, image_id)

Fetch the image from image_service and write it to the volume.

copy_volume_to_image(context, volume, image_service, image_meta)

Copy the volume to the specified image.

create_export(context, volume)

Exports the volume.

Can optionally return a Dictionary of changes to the volume object to be persisted.

create_snapshot(snapshot)

Creates a snapshot.

create_volume(volume)

Creates a logical volume.

Can optionally return a Dictionary of changes to the volume object to be persisted.

create_volume_from_snapshot(volume, snapshot)

Creates a volume from a snapshot.

delete_snapshot(snapshot)

Deletes a snapshot.

delete_volume(volume)

Deletes a logical volume.

detach_volume(context, volume_id)

Callback for volume detached.

do_setup(context)

Any initialization the volume driver does while starting.

ensure_export(context, volume)

Synchronously recreates an export for a logical volume.

get_volume_stats(refresh=False)

Return the current state of the volume service.

If ‘refresh’ is True, run the update first.

initialize_connection(volume, connector)

Allow connection to connector and return connection info.

local_path(volume)

remove_export(context, volume)

Removes an export for a logical volume.

terminate_connection(volume, connector, force=False, **kwargs)

Disallow connection from connector.
