5.5 Set global spare and dedicated spare disks
Spare disks are used to provide an added layer of protection in case a member
disk of a VG fails. The system will automatically switch a spare disk in place of a
failed disk and start a rebuild. Global spares will be reserved to serve all VGs,
while Dedicated spares will serve only the VG it is assigned to.
Figure 5.7.1
