Is it possible to change the protocol (from B to C) while the drbd device is open and in use? The way I expect it would work (if it worked at all) is this: . take secondary down . change both primary and secondary configs from B to C . drbdadm adjust the primary resource . bring secondary up again Taking the secondary down while making the change on the primary would avoid the situation where the primary and secondary have different ideas about the current protocol.
