Class LUClusterPostInit

Check syntactic validity for the opcode arguments.

This method is for doing a simple syntactic check and ensure validity of opcode parameters, without any cluster-related checks. While the same can be accomplished in ExpandNames and/or CheckPrereq, doing these separate is better because:

• ExpandNames is left as as purely a lock-related function
• CheckPrereq is run after we have acquired locks (and possible waited for them)

The function is allowed to change the self.op attribute so that later methods can no longer worry about missing parameters.

Build hooks env.

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: base.LogicalUnit.BuildHooksEnv

Build hooks nodes.

Returns: tuple; (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. No nodes should be returned as an empty list (and not None).
