I think we just trapped into the same trouble with pvmove as described in 
https://bugzilla.redhat.com/show_bug.cgi?id=602516
https://bugzilla.redhat.com/show_bug.cgi?id=706036

Alasdair, could you please point are those patches in vanilla kernel 
(3.0-rc*) or linux-next, or some RH internal tree? 
This is not critical, though I'd like to try out patches.

 
This is a userspace bug not a kernel one.
There is a workaround, which is to perform the pvmove one LV at a time
using the --name option.  (For each LV, run pvmove -n <lvname>.)

The patched code is in the upstream lvm2 repository:
  git://sources.redhat.com/git/lvm2
  http://sourceware.org/cgi-bin/cvsweb.cgi/LVM2/doc/?cvsroot=lvm2
  http://sourceware.org/lvm2/

It was only last night that the code incorporating these changes passed
our public testsuite for the first time, so I think it is still
premature to be using this on production systems.  But this means I hope
to be in a position to make the first development release containing a
fix for the problems quite soon.  (I added assertions to catch other
instances of the related problems - it was more than just pvmove
affected.)

Thanks a lot for your reply.
We don't have a production machines here (just internal servers),
so I guess I could give it a try.


Best,
