Read repair is the only way to restore the missing replicas on the restored
node:
http://wiki.basho.com/display/RIAK/Replication#Replication-ForcingReadRepair

<http://wiki.basho.com/display/RIAK/Replication#Replication-ForcingReadRepair>Read
each key with R=2 to force the object to replicate to the restored node.

Thanks,
Dan
