normally, there should be some more information as just this.
have a look at your syslog or kernel log files,
or try that command by itself.

what is the difference between a physical and a logical partition?
all partitions are "logical", no?

no. it does not care.

	to set up drbd,
	it is not enough
	to create a config file
	and say /etc/init.d/drbd start.

you need to explicitly create the drbd meta data as well,
and initiate the initial sync.

you probably did neither of the latter yet.

may I suggest that you have a look at the users guide

read it.
read it again.
complain on this list about anything that still may seem unclear.

then follow chapter 5. "configuring drbd", and experiment with
the things in chapter 6. "common administrative tasks".
