Example -- Hot Spare Pool

Consider 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 RAID 1 volume. The hot spare pool could also be associated with other submirrors or RAID 5 volumes if desired.
