I think we have a problem:

root@fireball / # pvmove -v /dev/sdb1
     Finding volume group "data"
     Archiving volume group "data" metadata (seqno 4).
     Creating logical volume pvmove0
     Moving 59604 extents of logical volume data/data1
   Insufficient free space: 59604 extents needed, but only 118 available
   Unable to allocate mirror extents for pvmove0.
   Failed to convert pvmove LV to mirrored
