Take the lowest number of physical extents in the set of PVs in your VG and multiply it by 4, then use that number when doing your striping. LVM requires each stripe to be on a separate PV currently. > livecd root # vgdisplay > --- Volume group --- > VG Name group > System ID > Format lvm2 > Metadata Areas 4 > Metadata Sequence No 1 > VG Access read/write > VG Status resizable > MAX LV 255 > Cur LV 0 > Open LV 0 > Max PV 255 > Cur PV 4 > Act PV 4 > VG Size 13.91 GB > PE Size 4.00 MB > Total PE 3560 > Alloc PE / Size 0 / 0 > Free PE / Size 3560 / 13.91 GB > VG UUID DjxWid-oxqx-zol9-Lu8a-CO94-AsBn-c7k3le > > livecd root # lvcreate -i4 -I16 -l3560 -nstorage group > Insufficient allocatable extents suitable for striping for logical volume > storage: 3560 required > livecd root # lvcreate -i4 -I16 -l3000 -nstorage group > Insufficient allocatable extents suitable for striping for logical volume > storage: 3000 required > > Even if I try to use less space then it says I have, it still wont let me. > > I've had this error before, but never found a solution.
