I've tried to lvextend and get the same error, even when trying to extend just 1Gbyte. 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' > -----Mensaje original----- > De: AJ Lewis [mailto:alewis@redhat.com] > Enviado el: martes, 04 de enero de 2005 20:40 > Para: LVM general discussion and development > Asunto: Re: Extending a stripped Logical Volume > > Olmo González <olmo@olmo.org> writes: > > > 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.
