That sound about right, although I'm not entirely familiar
with LVM to tell you a good answer.
Can you use the 'dd.raw' to DD into and out of the device,
so that you know your raw I/O is working?
If so, then it's an LVM issue ... otherwise, it could still
be a raw I/O configuration issue. Hope this helps ...
