Unfortunately the problem isn't solved when I disable clustering (-o
noclusterr,noclusterw), files are still getting corrupted.
Btw, it isn't possible to disable clustering in RELENG_7 unless this
patch is applied:
http://www.freebsd.org/cgi/cvsweb.cg...1.176;r2=1.177

Let me know if I can do further testing, so far all I can say is that
md5 checksums don't match before/after the copy process.
