WaitForResourcesStop waits for CRM resources to stop

It returns a flag indicating whether resources are stopped (true) or not (false), and an error.

type ClusterProperty

type ClusterProperty string

const (
	StonithEnabled ClusterProperty = "cib-bootstrap-options-stonith-enabled"

LrmRunState represents the state of a CRM resource.

const (
	// Unknown means that the resource's state could not be retrieved
	Unknown LrmRunState = iota
	// Running means that the resource is verified as running
	Running
	// Stopped means that the resource is verfied as stopped
	Stopped
)
