With time, most Linux users find LVM easy to get to grips with. Follow these basic steps to add a new logical volume on LVM:
Add any physical storage devices, like hard drives, you want to be managed by LVM.
Create a new physical volume (PV) from the entire hard drive or just a partition.
You can add the new physical volume to an existing volume group (VG) or you can create a new VG.
New logical volumes (LV) can be created from the new volume group.
You can install a filesystem on the LV you have created using appropriate entries to mount the filesystem.
