I can't still do it...

I had to deactivate the LV, and activate it exclusivly on one node, and 
issue the pvmove, and I still get :

   Error locking on node node206.lan: device-mapper: create ioctl on 
VGa-pvmove0 failed: Device or resource busy
   Failed to suspend logicalvolumename
   ABORTING: Volume group metadata update failed. (first_time: 1)
