The cinder.volume.drivers.nfs Module

class NfsDriver(*args, **kwargs)

Bases: cinder.volume.drivers.nfs.RemoteFsDriver

NFS based cinder driver. Creates file on NFS share for using it as block device on hypervisor.

create_cloned_volume(volume, src_vref)

create_export(ctx, volume)

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

create_volume(volume)

Creates a volume

delete_volume(volume)

Deletes a logical volume.

do_setup(context)

Any initialization the volume driver does while starting

ensure_export(ctx, volume)

Synchronously recreates an export for a logical volume.

get_volume_stats(refresh=False)

Get volume status.

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

initialize_connection(volume, connector)

Allow connection to connector and return connection info.

remove_export(ctx, volume)

Removes an export for a logical volume.

terminate_connection(volume, connector, **kwargs)

Disallow connection from connector

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

Bases: cinder.volume.driver.VolumeDriver

Common base for drivers that work like NFS.

check_for_setup_error()

Just to override parent behavior.

create_volume(volume)

delete_snapshot(snapshot)

Do nothing for this driver, but allow manager to handle deletion of snapshot in error state.

delete_volume(volume)

ensure_export(ctx, volume)

local_path(volume)

Get volume path (mounted locally fs path) for given volume :param volume: volume reference
