The sequence of creating a LVM is usually the following: 1) fdisking the disk in question and creating partitions. In your case you may opt to create one hdb1 which will occupy the entire disk
2) Creating a physical volume using the pvcreate against hdb1 3) Running a vgscan so that the LVM subsystem knows what physical volumes are around 4) Create a volume group. Give it a name (such as kvvolgroup) with /dev/hdb1 vgcreate kvvolgroup /dev/hdb1 5) You then have to create a logical volume over kvvolgroup using lvcreate. If you leave thing defaulted, you'll end up with a device called /dev/kvvolgroup/lvol00 6) It's this lvol00 which you have to mkfs against and add to your fstab. For example: /dev/kvvolgroup/lvol00 /home ext3 defaults 1 2 The key commands that you have to look into are fdisk pvcreate vgscan vgcreate lvcreate mkfs Hope that's enough to get you started.
