In this example, /dev/sdc and /dev/sdd are the disks where the volume group testvg_1 is created.
Disks = { "/dev/sdc", "/dev/sdd" }
In this example, the DiskReservation resource is used to verify that disks are available only to one system. All LVM2 logical volumes on the LVM2 volume groups that are imported are started if the reservation is confirmed. You can then mount the logical volumes at a mount point.
Disks = { "/dev/sdc", "/dev/sdd", "/dev/sde" }
