"Corruption". What, exactly? What do the salvage logs say after the
fact, and what did the fileserver or volserver logs say was wrong about
the volume that required salvaging?

The fileserver and volserver just do normal userspace i/o. If you can
just perform some i/o on a similarly-configured device and filesystem
and get a similar thing to happen, that's probably an easier test case
for RedHat or whomever to look at. Maybe just fiddle around with 'dd' or
run a filesystem benchmark or something.
