Extending a stripped Logical Volume

Hi,

I am new to this list, seeking for some help.

I have setup LVM2 under debian sarge (2.6.8-k7 kernel).

I originally created a volumen group (nasvg) on 4 x ST3200822A ATA DISK drives. I created a stripped logical volume spanning these 4 disks and using up al PE's available. I then attached two aditional ST3200822A ATA DISK drives and I would now want to resive my logical volumen to use al the PE's provided by the two new disks. The problem is I can't extend the logical volume, getting the following error:

gollum:~# lvextend -L+1G /dev/nasvg/naslv
 Using stripesize of last segment 64KB
 Extending logical volume naslv to 746.23 GB
 Insufficient allocatable extents suitable for parallel use for logical 
volume naslv: 191036 required

I have been googl'ing and it seems that this has to do with restrictions on resizing sttriped LV's. However, the information I have found says the restrictions no longer apply to LVM2.

Any help would be appreciated. I'm thinking of creating a linear lv spanning al 6 disks but this would mean backing up ~600gb of data which could be a pain...

Here is my output for both vgdisplay and lvdisplay.
