Example -- Hot Spare Pool

Figure 3-1 illustrates a hot spare pool, hsp000, that is associated with submirrors d11 and d12 in mirror d1. If a slice in either submirror were to become errored, a hot spare slice would automatically be substituted for the errored slice. The hot spare pool itself is associated with each submirror metadevice, not the mirror. The hot spare pool could also be associated with other submirrors or RAID5 metadevices if desired.
