--- Distribution of logical volume on 2 physical volumes  ---
PV Name                                PE on PV     reads      writes
/dev/ide/host2/bus0/target0/lun0/part1 320          7182730    8829885
/dev/ide/host2/bus1/target1/lun0/part1 320          7182371    8826433

The reads/writes are evenly distributed between the two disks.
