This example procedure creates an LVM logical volume called new_logical_volume that consists of the disks at /dev/sda1, /dev/sdb1, and /dev/sdc1 . To use disks in a volume group, label them as LVM physical volumes with the pvcreate command. Warning. This command destroys any data on /dev/sda1, /dev/sdb1, and /dev/sdc1 .
