i)  It's is possible to deadlock pvmove under lvm1

ii) lvm1 does not have a transactional metadata format, so if you loose
    power during a metadata update you can have problems.

iii) I suspect you will have to restart the complete pvmove under lvm1
     if it's interrupted (Heinz ?)

Use LVM2.
