Spare disk list.
The advanced disk settings use a "spare disk list".
If a disk has more than the disk error boundary errors, or if a shadow member is no longer mounted in a shadow set, a disk from the spare disk list is added to the shadow set.
As a result, the shadow set is always configured with properly functioning shadow members.
Filling the spare disk list can be done by choosing Rebuild spare set. All unmounted disks are then possibly added to the spare disk list. A disk must be the same size as at least one shadow set to enter the spare disk list.
If the spare disk list no longer contains any disks, a notification will be made.
