We call them "primary" and "secondary". That is perfectly expected behavior. Imagine a resync from the primary that, for some time, makes the secondary inconsistent (see what Lars already told you). Would not make sense to mount that one... Error codes are limited, "Wrong medium type" is the one that makes most sense. For DRBD9 it is possible to mount a secondary RO when there is no primary.
