Restarting the head node

Prior to restarting the head node, it makes sense to terminate all the running instances because of the possible problems with the network. To do that make sure that have the admin environment for the ec2 tools and issue:

 ec2-describe-instances |grep i\-
 ec2-terminate-instances <instance-id1> <instance-id2> ... <instance-idN> 

After that one can restart the head node (CC and CLC) in the following order:

 $EUCALYPTUS/etc/init.d/eucalyptus-cloud stop
 $EUCALYPTUS/etc/init.d/eucalyptus-cc restart
 $EUCALYPTUS/etc/init.d/eucalyptus-cloud start
