To replicate a running system, you will have to decide whether you want internal-meta-data or external. For internal you need to shrink the to-be- replicated filesystem in its partition to make room for the meta-data. Then you create the configuration and maybe also start drbd on the second node already. On the first node you have to unmount the filesystem for a short time, create the meta-data, start drbd and while it synces the slave, you can already mount the filesystem again by its new device (you have to mount the drbd-device!) Best test this procedure one or two times before doing it live. And get enough sleep before doing this kind of change in the middle of the night (if thats the best time to shut down the fs)...
