Thanks, Felix. Actually, I figured nobody answered my questions because
there were dumb. Classic RTFM stuff. If I had perused the DRBD user
guide, I would have seen that all versions of 8.x are protocol
compatible and that rolling upgrades are possible. Also, if I had simply
read my drbd.conf file, I would have seen that internal metadata is
specififed. My bad.
