Yes, you can simply hot plug in the failed node back by starting sheep
daemon. Nothing else you need to do. Data will be automatically
re-balanced and recovered.
You can easily scale out the cluster by hot plug in more nodes by
starting sheep daemon on the new nodes. You can hot unplug the nodes
safely by collie if you want to shrink the storage.
