Same thing that needs to happen anytime you hot-add LUNs and want to detect
their partitions: run 'partprobe'  It's an order of operations thing, the
initscripts get all the partition, then use those partitions to setup DRBD
devices, which in turn have more partitions you need to detect but the
initscripts assume all the partitions are discovered by the time DRBD starts
so it never checks again.  Invoking 'partprobe' manually invokes partition
discovery.  This is rather distribution specific initialization detail, but
that's the deal.
