If you browse the archive for the last month you will find a couple of
threads on the subject.

I've posted a cruel patch to make pvmove ignore read-errors, and update
the meta-data even if the sector is bad. (The extent will be moved to
the other disk, but contain garbage). With this patch the behaviour is
undefined when moving more than one PE. Other than that, I think it
should work.

Others posted suggestions and possible some patches too - allthough
there was no complete perfect solution, I think you should be able to
make it work from the different tips submitted in the thread.
