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, you use the DiskReservation resource to verify that disks are available only to one system. The LVM2 logical volumes on the LVM2 volume groups that are imported are started if the reservation is confirmed. The logical volumes can then be mounted at a mount point.
Disks = { "/dev/sdc", "/dev/sdd", "/dev/sde" }
BlockDevice = "/dev/mapper/lvmvg01-lvmvol01"
mnt_lvmvol01 requires lvmvol01
