Cluster Shutdown

Because of the quorum requirement of the cluster infrastructure, more than half of the cluster nodes need to be avaiable. This requirement has to be temporarily removed for a complete cluster shutdown. This can be done by setting the number of expected votes to N+1 .:

     On one node 
     # cman_tool votes -v (N+1)

with expected votes set to N+1, the other cluster members can be shut down.:

     On all other nodes
     # shutdown -h now

after all other nodes have been shut down, the remaining one can also be shut down.:

     On the remaining node
     # shutdown -h now
