(*args, **kwargs)¶Bases: cinder.volume.driver.ISCSIDriver
OpenStack Cinder drivers for Synology storage.
CI_WIKI_NAME

= '1.0.0'¶check_for_setup_error
()¶create_cloned_volume
(volume, src_vref)¶Creates a clone of the specified volume.
create_export
(context, volume, connector)¶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.
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.
do_setup
(context)¶Any initialization the volume driver does while starting.
ensure_export
(context, volume)¶Synchronously recreates an export for a volume.
extend_volume
(volume, new_size)¶Extend an existing volume’s size.
get_volume_stats
(refresh=False)¶Get volume status.
If ‘refresh’ is True, run update the stats first.
initialize_connection
(volume, connector)¶Initializes the connection and returns connection info.
The iscsi driver returns a driver_volume_type of ‘iscsi’. The format of the driver data is defined in _get_iscsi_properties. Example return value:
{
'driver_volume_type': 'iscsi',
'data': {
'target_discovered': True,
'target_iqn': 'iqn.2010-10.org.openstack:volume-00000001',
'target_portal': '127.0.0.0.1:3260',
'volume_id': 1,
'discard': False,
}
}
If the backend driver supports multiple connections for multipath and for single path with failover, “target_portals”, “target_iqns”, “target_luns” are also populated:
{
'driver_volume_type': 'iscsi',
'data': {
'target_discovered': False,
'target_iqn': 'iqn.2010-10.org.openstack:volume1',
'target_iqns': ['iqn.2010-10.org.openstack:volume1',
'iqn.2010-10.org.openstack:volume1-2'],
'target_portal': '10.0.0.1:3260',
'target_portals': ['10.0.0.1:3260', '10.0.1.1:3260'],
'target_lun': 1,
'target_luns': [1, 1],
'volume_id': 1,
'discard': False,
}
}
remove_export
(context, volume)¶Removes an export for a volume.
terminate_connection
(volume, connector, **kwargs)¶Disallow connection from connector

update_migrated_volume
(ctxt, volume, new_volume, status)¶Return model update for migrated volume.
