-
class
ironic.drivers.modules.storage.external.
ExternalStorage
(*args, **kwargs)[source]¶ Bases:
ironic.drivers.base.StorageInterface
Externally driven Storage Interface.
-
attach_volumes
(task)[source]¶ Informs the storage subsystem to attach all volumes for the node.
- Parameters
task – A TaskManager instance.
- Raises
UnsupportedDriverExtension
-
detach_volumes
(task)[source]¶ Informs the storage subsystem to detach all volumes for the node.
- Parameters
task – A TaskManager instance.
- Raises
UnsupportedDriverExtension
-
get_properties
()[source]¶ Return the properties of the interface.
- Returns
dictionary of <property name>:<property description> entries.
-
should_write_image
(task)[source]¶ Determines if deploy should perform the image write-out.
This enables the user to define a volume and Ironic understand that the image may already exist and we may be booting to that volume.
- Parameters
task – The task object.
- Returns
True if the deployment write-out process should be executed.
-
validate
(task)[source]¶ Validate the driver-specific Node deployment info.
This method validates whether the ‘driver_info’ and/or ‘instance_info’ properties of the task’s node contains the required information for this interface to function.
This method is often executed synchronously in API requests, so it should not conduct long-running checks.
- Parameters
task – A TaskManager instance containing the node to act on.
- Raises
InvalidParameterValue on malformed parameter(s)
- Raises
MissingParameterValue on missing parameter(s)
