A typical command sequence is:
drbdadm create-md resource
drbdadm adjust resource
drbdadm primary --force resource

The text following /dev/drbd must be parsable as a valid minor number,
e.g., /dev/drbd1. An alternative is to use "device minor 1;", which will
also create /dev/drbd1 when the resource is started.

Valid minor numbers are in the range from 0 to 1048575 (inclusive).

In other words, /dev/drbd205 works, but /dev/drbd205a, /dev/drbda205,
/dev/drbd20a5, etc. do not, because the part following /dev/drbd is not
parsable as a number.
