In this example of direct attached storage (DAS), a SCSI drive with two partitions, /dev/sda1 and /dev/sda2, is attached to a Linux host. The /dev/sda1 partition is bootable and supports the system software. The /dev/sda2 partition contains a logical volume configured as a storage pool and mounted to the Linux root file system by Logical Volume Management (LVM). The storage pool uses only 1.5GB of the partition, leaving 13GB of storage available for additional logical volumes.Figure 1.
