Method Details [hide private]

BuildHooksEnv(self)

source code 

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: LogicalUnit.BuildHooksEnv

BuildHooksNodes(self)

source code 

Build hooks nodes.

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

CheckPrereq(self)

source code 

Check prerequisites.

This checks whether the cluster is empty.

Any errors are signaled by raising errors.OpPrereqError.

Overrides: LogicalUnit.CheckPrereq

Exec(self, feedback_fn)

source code 

Destroys the cluster.

Overrides: LogicalUnit.Exec
