In spite of having 'fence_tool leave' and 'cman_tool leave remove' in the 
'cman' init script, when stopping the five-member cluster, it looses 
quorum when only two machines run the cluster components:

'/etc/init.d/cman stop' was issued and executed successfully on the tree 
other nodes.

What can be the problem here?
