Do not assign a hot spare pool to a submirror in a one-way mirror. Failed slices in a one-way mirror cannot be replaced by a hot spare. In these metadevices, no other copy of data is available to reconstruct on the hot spare. • Why should hot spares be defined on different controllers? To maximize their availability in case of controller errors or failures.
