intentional behavior.
drbadm primary all should says something like
"Local replica is inconsistent (--do-what-I-say ?)"

so it already gives you that hint: it needs to be forced,
and you need to give it that additional option.

now, since it is not a drbdadm option, but a drbdsetup option,
you'd need to use drbsetup...
but drbdadm is able to pass options to drbdsetup:

USAGE: drbdadm [OPTION...] [-- DRBDSETUP-OPTION...] COMMAND {all|RESOURCE...}

so, what you actually want to do is
 drbdadm -- --do-what-I-say primary all
but you should be sure that you really mean what you say!

sounds reasonable...
