@classmethod
def _ComputeDiskBarrierArgs(cls, disabled_barriers, disable_meta_flush):

Compute the DRBD command line parameters for disk barriers

@staticmethod
def _GetResource(minor):

Return the resource name for a given minor.

Currently we don't support DRBD volumes which share a resource, so we generate the resource name based on the minor the resulting volumes is assigned to.
