I expect you've already gotten to this, but FWIW: I simply divided the
underlying device into multiple partitions that were less than 16TB
(actually about 12TB each), set them each of those smaller partitions up as
a drbd device, and then made each of those drbd devices an LVM physical
volume within a single volume group.  That worked just fine.

It does make the heartbeat/pacemaker setup a little more complicated, but
only a little.

 As for a timeline for >16TB support, I don't have any idea.

Thank you for your response.  That is indeed the plan for now.  If support for 16TB is around the corner (The roadmap says 8.3), it would be nice to have the slightly less complicated heartbeat setup just to keep things simple.

Thanks again,
