CheckArguments(self)

source code

Check arguments.

Overrides: base.LogicalUnit.CheckArguments

ExpandNames(self)

source code

ExpandNames for CreateInstance.

Figure out the right locks for instance creation.

Overrides: base.LogicalUnit.ExpandNames

DeclareLocks(self, level)

source code

Declare LU locking needs for a level

While most LUs can just declare their locking needs at ExpandNames time, sometimes there's the need to calculate some locks after having acquired the ones before. This function is called just before acquiring locks at a particular level, but after acquiring the ones at lower levels, and permits such calculations. It can be used to modify self.needed_locks, and by default it does nothing.

This function is only called if you have something already set in self.needed_locks for the level.

Parameters:

level - Locking level which is going to be locked

Overrides: base.LogicalUnit.DeclareLocks

(inherited documentation)

BuildHooksEnv(self)

source code

Build hooks env.

This runs on master, primary and secondary nodes of the instance.

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): 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: base.LogicalUnit.BuildHooksNodes

_ReadExportInfo(self)

source code

Reads the export information from disk.

It will override the opcode source node and path with the actual information, if these two were not specified before.

Returns:: the export information

_ReadExportParams(self, einfo)

source code

Use export parameters as defaults.

In case the opcode doesn't specify (as in override) some instance parameters, then try to use them from the export information, if that declares them.

CheckPrereq(self)

source code

Check prerequisites.

Overrides: base.LogicalUnit.CheckPrereq

Exec(self, feedback_fn)

source code

Create and add the instance to the cluster.

Overrides: base.LogicalUnit.Exec
