Select which components you want to put the state database replicas on.

After a physical disk failure, a majority (1/2 of the total replicas, plus 1) of the state database replicas must be available, so distribute the replicas across different physical media and controllers in such a way that any single component failure leaves more than half the replicas undamaged.

You can place the state database replicas on dedicated slices, or you can place the state database replicas on slices that will later be used for other volumes. The system recognizes when a slice contains a state database replica and automatically skips over the portion of the slice reserved for the replica if the slice is used in a volume. The part of a slice reserved for the state database replica should not be used for any other purpose.

You can keep more than one copy of a state database on one slice, although you may make the system more vulnerable to a single point-of-failure (single disk or single controller) by doing so.
