AJ,

does this mean I can initially build a striped LV from two smaller
disks, let me say sda and sdb and later move the LE from sda to sdc
and from sdb to sdd (where sdc and sdb a bigger than sda/sdb)? 
It is to be said that the performance of md RAID0 is somewhat better
than from striped LV's but I would prefer LVM if I could extend
a striped LV without rebuilding RAID/restoring data.

cu,
Jan
