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.

You should be able to 'lvextend -L+1G /dev/nasvg/naslv -i1' if you
have and additional 1G of free space in the VG. However, based on the
vgdisplay output below, it looks like you only have 3.72G free (or
95388 extents), so you'd want do do: 'lvextend -l+95388
/dev/nasvg/naslv -i2' if you want to stripe it across the 2 new disks,
or 'lvextend -l+95388 /dev/nasvg/naslv -i1' if you want it to be a
linear segment.

Hi,
Thanks for your reply.
95388 PE of 4mb each is ~370 Gbyte, right? I may be missing something... I've tried to lvextend and get the same error, even when trying to extend just 1Gbyte.
Thanks for your help,
Olmo.

You had 4 disks originally, and you striped across all of them,
presumably with -i4. Now you added 2 disks, and you're trying to
stripe 4 ways across them (because lvm2 defaults to the stripe size of
the previous segment). This will fail because you don't have 4 disks
to stripe across. To do this, you will need to specify '-i2' to your
lvextend command. If the free space is split evenly across the 2 new
disks, you should be able to fill the entire vg with 'lvextend -l95388
-i2 /dev/nasvg/naslv'
