ccs_sync is not alled automatically from anywhere at the moment. it's on 
the list of things to implement but it hasn't happened yet. There is 
also a bug in some version of corosync (sorry, I can't be more specific 
here) that causes it to loop like that if you issue a cman_tool version 
command and the local cluster.conf does not match the version expected.

The correct update procedure for cluster3 is to manually use ccs_sync to 
copy cluster.conf around the cluster, then to issue cman_tool version 
-r0 to tell cman that the new version is available.
