Simply replacing a failed disk requires a very long time if the ring is not changed, because all data will be replicated to a single new disk. This extends the time to recover from missing replicas, and becomes even more important with bigger disks. This patch updates the doc to include a faster alternative by setting the weight of a failed disk to 0. In this case the partitions from the failed disk are distributed and replicated to the remaining disks in the cluster, and because each disk gets only a fraction of the partitions it's also much faster.
