cinder.volume.drivers.drbdmanagedrv
Module¶This driver connects Cinder to an installed DRBDmanage instance, see http://drbd.linbit.com/users-guide-9.0/ch-openstack.html for more details.
DrbdManageBaseDriver
(*args, **kwargs)¶Bases: cinder.volume.driver.VolumeDriver
Cinder driver that uses DRBDmanage for storage.
CI_WIKI_NAME
= 'Cinder_Jenkins'¶VERSION
= '1.1.0'¶call_or_reconnect
(fn, *args)¶Call DBUS function; on a disconnect try once to reconnect.
check_for_setup_error
()¶Verify that requirements are in place to use DRBDmanage driver.
create_cloned_volume
(volume, src_vref)¶Creates a clone of the specified volume.
If volume_type extra specs includes ‘replication: <is> True’ the driver needs to create a volume replica (secondary) and setup replication between the newly created volume and the secondary volume.
create_snapshot
(snapshot)¶Creates a snapshot.
create_volume
(volume)¶Creates a DRBD resource.
We address it later on via the ID that gets stored as a private property.
create_volume_from_snapshot
(volume, snapshot)¶Creates a volume from a snapshot.
dbus_connect
()¶delete_snapshot
(snapshot)¶Deletes a snapshot.
delete_volume
(volume)¶Deletes a resource.
do_setup
(context)¶Any initialization the volume driver does while starting.
drbdmanage_dbus_interface
= '/interface'¶drbdmanage_dbus_name
= 'org.drbd.drbdmanaged'¶extend_volume
(volume, new_size)¶is_clean_volume_name
(name, prefix)¶local_path
(volume)¶snapshot_name_from_cinder_snapshot
(snapshot)¶DrbdManageDrbdDriver
(*args, **kwargs)¶Bases: cinder.volume.drivers.drbdmanagedrv.DrbdManageBaseDriver
Cinder driver that uses the DRBD protocol.
create_export
(context, volume, connector)¶Exports the volume.
Can optionally return a Dictionary of changes to the volume object to be persisted.
ensure_export
(context, volume)¶Synchronously recreates an export for a volume.
get_volume_stats
(refresh=False)¶Get volume status.
initialize_connection
(volume, connector)¶Allow connection to connector and return connection info.
Parameters: |
|
---|---|
Returns conn_info: | |
A dictionary of connection information. |
remove_export
(context, volume)¶Removes an export for a volume.
terminate_connection
(volume, connector, force=False, **kwargs)¶Disallow connection from connector
Parameters: |
|
---|
DrbdManageDriver
¶alias of cinder.volume.drivers.drbdmanagedrv.DrbdManageIscsiDriver
DrbdManageIscsiDriver
(*args, **kwargs)¶Bases: cinder.volume.drivers.drbdmanagedrv.DrbdManageBaseDriver
Cinder driver that uses the iSCSI protocol.
create_export
(context, volume, connector)¶Exports the volume.
Can optionally return a Dictionary of changes to the volume object to be persisted.
ensure_export
(context, volume)¶Synchronously recreates an export for a volume.
get_volume_stats
(refresh=False)¶Get volume status.
initialize_connection
(volume, connector)¶Allow connection to connector and return connection info.
Parameters: |
|
---|---|
Returns conn_info: | |
A dictionary of connection information. |
remove_export
(context, volume)¶Removes an export for a volume.
terminate_connection
(volume, connector, **kwargs)¶Disallow connection from connector
Parameters: |
|
---|
validate_connector
(connector)¶Fail if connector doesn’t contain all the data needed by driver.
