ganeti.cmdlib.base.NoHooksLU

Class NoHooksLU

Simple LU which runs no hooks.

This LU is intended as a parent for other LogicalUnits which will run no hooks, in order to reduce duplicate code.

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) or (list, list, list): Tuple containing a list of node UUIDs on which the hook should run before the execution and a list of node UUIDs on which the hook should run after the execution. As it might be possible that the node UUID is not known at the time this method is invoked, an optional third list can be added which contains node names on which the hook should run after the execution (in case of node add, for instance). No nodes should be returned as an empty list (and not None).
