you should compare kernel logs during DRBD configuration
of the working and non-working setup.
you could also try to add "no-md-flushes"
(and probably also no-disk-flushes) to your drbd configuration.
it is possible that those "disks" do not support barriers,
but do not return "-EOPNOTSUPP", as they are supposed to, but rather
error out generically ("-EIO"), or in any other way,
making it look like an IO error.
in more recent DRBD versions we do no longer care
for the exact error value of failed barrier requests,
but retry without the barrier flag set, anyways.
because of such misbehaviour.
