drbd 8.4.x contains compatibility executables drbdsetup-83 and
drbdadm-83, which are exec()'d if the userland detects that the
kernel is running drbd 8.3.<br>
<br>
However there is a case where this doesn't seem to be compatible.<br>
<br>
"ganeti" issues the following drbdsetup command:<br>

This is accepted (silently, exitcode 0) by drbdsetup from 8.3.10.
It's also accepted if you pass it explicitly to
/lib/drbd/drbdsetup-83.<br>
<br>
However if you pass this to drbdsetup in 8.4 it is rejected with a
"USAGE: drbdsetup command device arguments options" error. So the
frontend drbdsetup is rejecting this command *before* giving it to
drbdsetup-83.<br>
