Cluster disk resource '%1' contains a BitLocker-protected volume, '%2', but for this volume, the Active Directory cluster name account (also called the cluster name object or CNO) is not a BitLocker protector for the volume. This is required for BitLocker-protected volumes. To correct this, first remove the disk from the cluster. Next, use the Manage-bde.exe command-line tool to add the cluster name as an ADAccountOrGroup protector, using the format domain\ClusterName$ for the cluster name. Then add the disk back to the cluster. For more information, see the documentation for Manage-bde.exe;
