is it possible that you set up drbd with internal meta data on top of an
existing filesystem, and you happen to have overlooked the line in the
documentation where it says DO SHRINK THE FS FIRST ?

if not, do you happen to use drbd with internal meta data, but you
mkfs'ed on the lower level device? Don't do that, then.
