direct links of old sources may well be a few messages off.

Awesome - now, here's the million dollar question.  Not counting the resync, how difficult is this to do without taking it offline?

* Resource s0 on Node A and Node B
* Set up a new device the same size as s0 on Node C
* Take Node B offline (leaving A as Primary/Unknown)
* Modify the config on Node A so that Node C is now the secondary - running drbdadm adjust s0
* Bring Node C online and letting it resync to Node C

Is THIS possible without taking down DRBD?

Thanks a bunch,
Mike Sweetser
