For the benefit of other readers, I wish to add that the same problem occurs when creating lvm mirrors (e.g. "lvconvert -m1 vg/lvol"), which is not surprising since pvmove works itself by creating a mirror. Consequently, mirror creation should also be avoided until the root cause of the problem is eliminated.
