BuildHooksEnv(self)

source code

Empty BuildHooksEnv for NoHooksLu.

This just raises an error.

Returns: dict: Dictionary containing the environment that will be used for running the hooks for this LU. The keys of the dict must not be prefixed with "GANETI_"--that'll be added by the hooks runner. The hooks runner will extend the environment with additional variables. If no environment should be defined, an empty dictionary should be returned (not None).
Overrides: LogicalUnit.BuildHooksEnv

BuildHooksNodes(self)

source code

Empty BuildHooksNodes for NoHooksLU.

Returns: tuple; (list, list): Tuple containing a list of node names on which the hook should run before the execution and a list of node names on which the hook should run after the execution. No nodes should be returned as an empty list (and not None).
Overrides: LogicalUnit.BuildHooksNodes
