ironic.drivers.modules.storage.external module

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)
