I never did this, but there is a subcommand for drbdadm: resize.
>From the man page:
resize Causes DRBD to re-examine all sizing constraints, and resize
the resource's device accordingly. For example in case you
increased the size of your backing storage devices (on both
nodes of course), then DRBD will adopt to the new size after you
called this command on one of your nodes. Since new storage
space must be synchronised this command only works if there is
at least one primary node present.
