Lets assume the /music directory has the following permissions:

The physical partitions map to Physical Volumes (PV’s). So in Figure 1 the physical volumes are /dev/sdb1, /dev/sdb2, /dev/sdc1, and /dev/sdc2. From the Physical Volumes (PV’s), a Volume Group (VG) is created. A VG can use all or just one of the PV’s. In the example in Figure 1, the four PV’s are used in a single VG, primary_vg (note: the VG name actually ends in “_vg” to make it more noticeable). After creating one or more VG’s (Volume Groups), a Logical Volume (LV) is created. You have to have at least one Logical Volume (LV) per Volume Group (VG). These LV’s are used for creating file systems. In Figure 1, the VG is broken into two LV’s: /dev/primary_vg/home_lv and /dev/primary_vg/data_lv (again note the use of the “_lv” at the end of the name to better indicate a LV). Then on top of these these two PV’s are the file systems. For /dev/primary_vg/home_lv an ext3 file system is created and mounted as /home. For /dev/primary_vg/data_lv an xfs file system is created and mounted as /data.
