Andreas, this is a matter of units used. fdisk shows 292555849728 Bytes / 1000^3 rounded to 292.5GB whereas LVM uses 1024(2^10) per order of magnitude -> 292555849728 Bytes / 1024^3 = 272.45GB (which it shows below in the vgdisplay output). # lvcreate -c 8k -l 34873 -n lvo1 vg_daten allocates all free physical extents in your VG to your new logical volume.
