A revised procedure would be the following: - Add disk to system - Partition it via fdisk. Set partition type to 8e (Linux LVM) - run pvcreate initialize the partition for LVM - run vgextend to expand your existing volume group with the new device. - run lvextend to grow your logical volume. - finally, run resize2fs (assuming you are using ext3/4) to grow the file system.
