def BuildHooksEnv(self):
overrides ganeti.cmdlib.base.LogicalUnit.BuildHooksEnv

Build hooks env.

def BuildHooksNodes(self):
overrides ganeti.cmdlib.base.LogicalUnit.BuildHooksNodes

Build hooks nodes.

This doesn't run on the target node in the pre phase as a failed node would then be impossible to remove.

def CheckPrereq(self):
overrides ganeti.cmdlib.base.LogicalUnit.CheckPrereq

Check prerequisites.

This checks:

  • the node exists in the configuration
  • it does not have primary or secondary instances
  • it's not the master

Any errors are signaled by raising errors.OpPrereqError.

def Exec(self, feedback_fn):
overrides ganeti.cmdlib.base.LogicalUnit.Exec

Removes the node from the cluster.
