[linux-lvm] lvm unstriping

["Edgar Costa" <dane netcabo pt>]

at first i striped my partitions by 3 disks but
then there was a need to remove one so i make pvmove, now what happens
is that now i lose performance because the disk his always jumping from
where it reads/writes 
for example onde de / (not in lvm) with hdparm i get 232 / 50 mb/s and  in a lvm partition 193 / 5.8

so i need to unstrip the logical volumes

but the question is: how?

there is any reshaper? or something like that? 
i already found out that pvmove can move only a PE at a time but this will be very lame, I would have to make a script to make my efficient again, and it's a easy way to get it worse...(if i get something wrong)
