to get out of this,
first, you should trigger a full sync.
on the "bad" node, say "drbdadm invalidate all".

also, you should upgrade drbd to 0.7.22.
there have been a number of bugs fixed since 0.7.14, some of which may
-- in certain error scenarios -- even lead to diverging data on both
nodes.  however, none of them would lead to data being inconsistent on
the _bit_ level, as Luciano already pointed out.
