BuildHooksEnv(self)

source code

Build hooks env.

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

Overrides: LogicalUnit.BuildHooksEnv

CheckPrereq(self)

source code

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.

Overrides: LogicalUnit.CheckPrereq

Exec(self, feedback_fn)

source code

Removes the node from the cluster.

Overrides: LogicalUnit.Exec
