From AI Now I see the issue clearly. The auto-disk detection in /opt/ovf/ovfstartup.sh (lines 66-92) only works with LVM: bash pvs | grep -q $disk # checks if disk is in LVM pvcreate /dev/$disk # adds to LVM vgextend $VGS /dev/$disk # extends volume group lvextend -l +100%FREE ... # extends root LV resize2fs $ROOTLV # resizes filesystem Since your root /dev/sda2 is a plain ext4 partition (not LVM), this entire block silently skips the disk. The script finds /dev/sdb, runs pvs | grep -q sdb which fails (sdb isn't an LVM PV), then falls into the if [ $? != 0 ] branch — but then pvcreate, vgs, vgextend, lvextend all fail because there's no VG to extend.
