Method Details

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: base.LogicalUnit.BuildHooksEnv

BuildHooksNodes(self)

source code

Build hooks nodes.

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).
Overrides: base.LogicalUnit.BuildHooksNodes

CheckPrereq(self)

source code

Check prerequisites.

This checks whether the cluster is empty.

Any errors are signaled by raising errors.OpPrereqError.

Overrides: base.LogicalUnit.CheckPrereq

Exec(self, feedback_fn)

source code

Destroys the cluster.

Overrides: base.LogicalUnit.Exec
