I am using .0.7.2

It says: 

This example already uses /dev/drbdX instead of /dev/nbX, what you might
have expected. For historical reasons DRBD used to hijack NBDs device
major (43), and device nodes. We now have an officially assigned DRBD
major (147), therefore starting with 0.7.1 we default to use our own
major numbers and device nodes. (Unfortunately the assignment was a few
days late for 0.7.0; so your distribution may have decided to stay with
the deprecated /dev/nbX # major 43) 

If your system does not know about /dev/drbdX yet, you should create
these device nodes like for i in $(seq 0 15) ; do mknod /dev/drbd$i b
147 $i ; done. See also the upgrade*.txt files, mentioned earlier.
