cinder.volume.drivers.lvm
Module¶Driver for Linux servers running LVM.
LVMVolumeDriver
(vg_obj=None, *args, **kwargs)¶Bases: cinder.volume.driver.VolumeDriver
Executes commands relating to Volumes.
CI_WIKI_NAME
= 'Cinder_Jenkins'¶VERSION
= '3.0.0'¶check_for_setup_error
()¶Verify that requirements are in place to use LVM driver.
clone_image
(context, volume, image_location, image_meta, image_service)¶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_cloned_volume
(volume, src_vref)¶Creates a clone of the specified volume.
create_export
(context, volume, connector, vg=None)¶create_snapshot
(snapshot)¶Creates a snapshot.
create_volume
(volume)¶Creates a logical volume.
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.
ensure_export
(context, volume)¶extend_volume
(volume, new_size)¶Extend an existing volume’s size.
get_manageable_snapshots
(cinder_snapshots, marker, limit, offset, sort_keys, sort_dirs)¶get_manageable_volumes
(cinder_volumes, marker, limit, offset, sort_keys, sort_dirs)¶get_pool
(volume)¶get_volume_stats
(refresh=False)¶Get volume status.
If ‘refresh’ is True, run update the stats first.
initialize_connection
(volume, connector)¶local_path
(volume, vg=None)¶manage_existing
(volume, existing_ref)¶Manages an existing LV.
Renames the LV to match the expected name for the volume. Error checking done by manage_existing_get_size is not repeated.
manage_existing_get_size
(volume, existing_ref)¶manage_existing_object_get_size
(existing_object, existing_ref, object_type)¶Return size of an existing LV for manage existing volume/snapshot.
existing_ref is a dictionary of the form: {‘source-name’: <name of LV>}
manage_existing_snapshot
(snapshot, existing_ref)¶manage_existing_snapshot_get_size
(snapshot, existing_ref)¶migrate_volume
(ctxt, volume, host, thin=False, mirror_count=0)¶Optimize the migration if the destination is on the same server.
If the specified host is another back-end on the same server, and the volume is not attached, we can do the migration locally without going through iSCSI.
remove_export
(context, volume)¶retype
(context, volume, new_type, diff, host)¶Retypes a volume, allow QoS and extra_specs change.
revert_to_snapshot
(context, volume, snapshot)¶Revert a volume to a snapshot
terminate_connection
(volume, connector, **kwargs)¶update_migrated_volume
(ctxt, volume, new_volume, original_volume_status)¶Return model update from LVM for migrated volume.
This method should rename the back-end volume name(id) on the destination host back to its original name(id) on the source host.

Returns: | model_update to update DB with any needed changes |
