+Stop And Restart
+================
+
+Stop The Cluster
+****************
+
+It's very important to stop the cluster in the right way to avoid corruption
+of vdi.
+
+First of all, shut down all virtual machines on every node.
+Once done, run
+
+::
+
+    # dog cluster shutdown
+  
+This will kill all sheep daemon on all nodes, without start/interrupt any
+rebuilding.
+Now it's safe to shut down the hosts.
+
+**Remember:
+DO NOT shut down any of node before deactivating the cluster!
+DO NOT shut down / kill a node after the other.**
+
+Restart The Cluster
+*******************
+
+Run sheep daemon on every node, on the same directory as before.
+Don't wary, no rebuild will start after the second or third node goes on.
+If sheepdog has been stopped with 4 nodes alive, the cluster will not start
+till all 4 nodes will be on line.
+
+E.g. start sheep on the first node and run
+
+::
+
+    dog cluster info
+    
+    Cluster status: Waiting for other nodes to join cluster
